Nagi (凪, Nagi), now known as Chrome Dokuro (クローム 髑髏, Kurōmu Dokurō), is a 13-year-old Japanese girl who was first introduced as Tsuna's mysterious Mist Guardian and one of Mukuro's subordinates who acted as his vessel and connection to the world outside Vendicare Prison.
Chrome is a small girl with short purple hair syled in a 'pineapple' style similiar to Mukuro's. She has one violet eye, the other covered by a black eye patch with a chrome-colored skull. She is usually seen wearing the green Kokuyo Middle-school uniform like the rest of the Kokuyo Gang; however, her clothes are accessorized with her eypatch, a black belt, and black boots, all embelished with a chrome-colored skull, reflecting her name, Chrome Dokuro (Dokuro means "skull" in Japanese). She's usually seen with her bag, in which she stores her trident.
When in an illusionay world, she has longer hair with bangs covering her lost right eye, and is always seen wearing a plain white gown (anime only). Her appearance before her fatal car accident as Nagi was not seen.
The Future her was never shown in the manga plot, but Akira Amano drew her wearing a white top studded with amber as well as a necklace. Her bangs grew out and her hair is longer.
Due to her once anti-social life as Nagi, she never opens up to anyone except Mukuro, the first person who accept her as she is, and always gets confused and shy when someone is kind to her since she had never imagined that her existence could be accepted by people. Because of her nature, some people can't be honest with her or think of her as pitiful. She used to tend on Mukuro for help, but as the story progress, she becomes determined to get stronger to help the people who are dear to her and slowly starts to interact with the others.
HistoryFrom what her parents talked about in a flashback, her original name was Nagi, and she lived an isolated and antisocial life. After trying to rescue a cat, she was badly injured in a car accident, which led to the loss of her right eye and some of her internal organs. The only way to save her life would be to have someone with the same blood type transfer their organs to her. She did not care whether she lived or not, and her mother refused to sacrifice her own organs anyway. However, Mukuro Rokudo heard her words and allowed her to live by creating illusionary organs. However, if hers or Mukuro's Trident breaks, her stomach will sink in due to not having genuine organs. Chrome has been shown using two of Mukuro's Six Paths of Reincarnation. She is also trying hard to learn Italian, since her goal is to someday be able to converse with Mukuro in Italian.
Chrome was chosen to be the holder of the Half Vongola Mist Ring in Mukuro's place. She fought on level footing with Viper during the early stages of her match, but was overwhelmed once Viper got a bit serious. Viper, soon realizing that her trident was the key to her power, began targeting that, and, shortly after, was able to destroy it. This led to an unusual phenomenon where Chrome lost some of her organs, and seemingly lost the match.
However, soon a mist covered her body. Viper guessed that Chrome did what normal female illusionist do by using the last of her powers to cover her body. Viper couldn't be more wrong, because out of the mist came a sinister laugh, and, once the mist cleared, Mukuro had taken over.
Mukuro soon defeated Viper, winning the match, but having used too much of his power, his grip on his real illusion faded, returning the body back to Chrome.
Later, in the Sky Ring Battle, she was captured by Bel and Mammon and held hostage to convince Gokudera and Yamamoto to give up their Rings. Gokudera and Yamamoto attempted to save her but were caught in an illusion; however, Ryohei came to the rescue and broke the illusion.
After being transferred into the Future with a frozen Vongola Ring, Chrome was confronted by Glo Xinia in the Kokuyo Gang's Hideout. With the help of Future Mukuro, she was able to thaw out her Ring and defeat Glo Xinia. Ryohei later brought Chrome to the Vongola Base. As she lay in bed sick, her illusionary internal organs begin to fail and disappear due to Mukuro's defeat by Byakuran. However, she was able to use the Vongola Mist Ring to sustain her organs via her own Illusions. During the Invasion of the Merone Base, she appeared using Illusions to disguise herself with Hibari and Kusakabe. Along with the other Vongola Guardians, Chrome was given a Vongola Box Weapon.
Upon returning to the Future, the other members of the Famiglia were at first worried that Chrome wasn't eating. However, once she established a friendship with I-Pin, she began joining them for dinner. She later began training to master her Illusions with the virtual training challenge created by Mammon and her combat abilities with Bianchi and I-Pin. Chrome was not one of the participants in Choice and therefore watched the battle from the Vongola viewing area.Yuni, Kyoko, Haru and I-Pin, she stated that she no longer wished to fight, leading the other Guardians to think she would be better off staying in the past. It was later revealed that Daemon Spade (the Vongola First's and Second's Mist Guardian) had taken control of Chrome in order to draw the girls out and hold them as hostages. The group was then trapped in an illusion with limited oxygen, and while the other Guardians attempted a rescue Chrome attempted to break the illusion which, with Viper acting as a guide she was able to accomplish. Later Daemon gave Chrome her inheritance after expressing an interest in Mukuro, who had appeared briefly to save Chrome.
After returning from the past, the Six Funeral Wreaths tried to capture Yuni. Chrome used her Vongola Mist Owl Cambio Forma to see through the enhanced illusions created by Torikabuto, aiding Tsuna in his fight. During the day of the final battle, Chrome delivered the Vongola Mist Box to Mukuro but fainted shortly after seeing him for the first time. After Byakuran was defeated, M.M. warned Chrome that Mukuro was only using her to escape from prison.
Back in the past Chrome was stalked by Julie Katou (a transfer from Simon Middle School), who also started delivering food to her. He later asked her to go on a date and run away with him. However, she rejected him and just left him standing there. Later, after Yamamoto was attacked, Chrome created an illusion of him for Tsuna's Inheritance Ceremony so that the other Mafia members would remain unaware of his absence. Later, she, along with the other guardians (excluding Lambo), was defeated by Enma. When the Simon Famiglia took their leave after Enma defeated Tsuna, she was taken along by Julie, dropping her Vongola Ring on the ground in the process.
After awakening to find herself trapped at Simon Island, Chrome attempted to escape but was stopped by Julie who demonstrated that he was creating her illusionary organs for her as the Island had a barrier that prevents Mukuro's illusions from passing through. When Chrome refused his offer to become his, Julie then explained that he was responsible for the entire battle between the Simon and Vongola for two goals, first for complete annihilation of Vongola and second was her. As he said this, he revealed his true identity as Daemon Spade in disguise. When he requested for Chrome to submit her body by her own will, she refused and Daemon then punished her by proceeding to take control of Chrome's mind in order to draw out Mukuro so he can take his body. She's seen again alongside Daemon, after he finally revealed his true identity and plans to Tsuna and the others. She creates a mist barrier that traps Tsuna and the others with her technique, Cortina Nebbia, to prevent them fighting Daemon all together at once. When Hibari threatened Daemon by breaking the barrier, he replied to Tsuna and the group that if the barrier is broken; Chrome, the creator, will be killed. When Yamamoto managed to injure Daemon with his new technique, Chrome interfered and refused to step back until Daemon ordered her too. Before she left the battlefield with Daemon, Yamamoto gave her the Ore of Mist Version X and told her that they will always wait for her.The next day, when the Simon Ring finally fully awakened, she was tied up as Daemon undid the mind control on her and told her that he will let her meet Mukuro. Chrome asked why now, which he replied that it's a perfect time because he can fight Mukuro with the fully awakened Desert Simon Ring. Chrome realized that he was using her to lure out Mukuro and shouted that she won't let it happen. Daemon replied that no one is here to listen to her opinion, the one who will decide is Mukuro and he opened the barrier of the island. Chrome urgently asked him to stop, but it's already too late and Daemon removed her illusionary organs to lure out Mukuro; as Chrome spit out blood, she silently pleaded Mukuro to not come but soon blacked out. After this, mist surrounded Chrome and Mukuro appeared, replacing her. After the fight of Mukuro and Daemon, Mukuro leaves Chrome to Tsuna and changed back into Chrome. When she woke up she asks where is Mukuro and Tsuna replied that Mukuro had already defeated Daemon, making her glad. However, Chrome and the others were shortly surprised when they heard Mukurou, the box animal, speaking and knew that there was trouble regarding Mukuro's body in Vindice. Julie suddenly woke up and asked about the situation. Tsuna and Gokudera said that Daemon is still alive and is inside Julie which Chrome and Mukuro immediately replied that he is no longer Daemon. Mukuro concluded that Daemon had taken over his body, surprising them. At the confrontation with Daemon, she was saved by Yamamoto from being sent to Daemon's illusionary world. She intended to assist Tsuna and Enma to see through Daemon's illusions but Daemon threatened that he will kill her with Mukuro and Reborn if she were to assist them and told them to watch. However, she finally interferes when Tsuna hesitates to shoot Enma along with Daemon by protecting Enma with her Barrier Mist Flames in full power that were also supported by Mukuro.
Tsuna and the others are surprised to see that Chrome has been transferred to Nami Middle. She stood at the front of the classroom to introduce herself, but breaks down crying in Kyoko's arms. When discussing this between classes, Ryohei told them that according to what Kyoko has heard from Chrome, she was kicked out of Kokuyo Gang by Mukuro. Gokudera then commented that since Mukuro was free from jail, he doesn't need Chrome anymore. Tsuna seemed to have doubts about that representation of events. Reborn arrived and told them that he was convened by Mukuro to talk about Chrome. He was given her living expenses by Mukuro as well. Since Chrome has already arrived in Namimori, Reborn said that settling her in to either Kyoko or Haru's house would be for the best. Reborn then suggests a welcoming party for Chrome at Tsuna's house, with the theme of a mimicry contest. At the party, Chrome thanks everyone for throwing it for her with the moral support of Haru and Kyoko and holding a mimicry contest where the loser must become Chrome's errand boy for a year.Later on the first day of the Representative Battle of the Rainbow, she was shown to be having a cold. After school, on her way home, she was approached by illusion that Mukuro created to check on whether she was getting better or not; seeing her, he states that her condition has worsened. Mukuro tells Chrome to tell him everything about her condition; otherwise, she was going to die, much to Chrome's shock. The next day, Tsuna noticed that Chrome was not present at school and wondered did something happened to her.
After the second Representative Battle of the Rainbow, when Tsuna, Gokudera, and Yamamoto visited the hospital to check on Team Skull's condition after defeated by Team Bermuda, they bumped into Kyoko, who told them that Chrome's internal organs are gone. Tsuna rushed into Chrome's room and saw that she was really worn out. Tsuna apologized for not acting upon her absence even though he noticed it, but Chrome ignored his apology and instead requested Tsuna so she could be placed on Team Reborn. Tsuna refused as Reborn is the one who decides on the team and worried about her condition, but Chrome pleads to him; despite that, Tsuna still refuses. Later, however, during the battle between Team Reborn and Team Verde against Team Bermuda, Chrome appeared at the battlefield as Reborn's sixth representative and offered to support Mukuro's illusion, joining the fight. At this moment, the cause behind Chrome's illness is revealed; Chrome was torned between wanting to be seen as a single person as she is no longer sharing a body with Mukuro and rejects his illusion, but some part of her wants Mukuro to keep providing her with illusionary organs, making both her feelings and body grown worse. However, after finally found her resolve, Chrome able to recreate illusionary organs with her own power by using Verde's equipment and assisted Mukuro's illusion. By combining both of their illusions, they able to create a much more powerful version of Genju Gagaia, Genju Mugaia.
Chrome is extremely loyal and devoted to Mukuro, and cares deeply for him since he gave her a chance to live and was the first person who claimed that he needed her and accepted her, something that nobody, not even her own parents, ever did. She is very respectful of him, always adressing him as "Mukuro-sama." He was the first person she willingly opened up to, and still is the one she places her utmost trust in. Chrome is willing to do anything for his sake and safety, regardless of her fate's outcome, as shown when she firmly told Daemon Spade that she wouldn't help him and pleaded for Mukuro not to come, despite the fact that Daemon had removed her illusionary organs.
Mukuro, for his part, is kind towards her, although whether it is honest behavior or just an act is unknown. However, it seems he might genuinely care for her; during his battle with Glo Xinia, he reacts with surprise when Glo Xinia commented on how precious Chrome was to him. After the battle, Mukuro told Tsuna not to drag her out of his reach and even requested that he protect her. However, at the end of the Future Arc, M.M. warns her that Mukuro is a "fearful person" and that he was just using her to get out of Vendicare Prison. Future Mukuro referred to Chrome as an "ignorant little girl" who took his words and actions at face value. His feelings and motives become much more complex and confusing after he is freed out of the Vendice Prison; he kicked Chrome out of the Kokuyo Gang and told Tsuna that he detested the current her. However, despite these statements, Mukuro still visited her to check on her condition. He eventually revealed that he left her because he wanted her to become an independent warrior with the ability to stand up for herself, acknowledging her high potential. Despite his mysterious intentions, Chrome continues to love Mukuro, vowing to grow stronger and protect him and all those that are dear to him. Her feelings toward Mukuro are what motivated her to become stronger so she can always protect him.
Chrome sees them as important people she wants to protect. Even though Ken always mocks and berates her, she doesn't seem to mind it. And unlike Mukuro, where it's still unknown how he feels for her, Ken and Chikusa, actually, really care for her well-being but refuse to show it, especially Ken. Evidence of this can be seen when they saved her during the Cloud Ring Battle from a bomb explosion and the Sky Match where Ken constantly complained that they couldn't see Chrome's condition. In the Arcobaleno Trial Arc, Ken gave her many sweets and when asked by Chikusa, he said he only bought it because they haven't used any money since her disappearance. Chikusa, aware of Ken's real intention, accepts this story, much to Ken's anger. In Inheritance Succession Arc, both Ken and Chikusa were worried when Chrome came back crying after missing for few days and Ken tried to cheer her up by bought her many sweets, which he hotly denied when Chikusa realized his attention. Ken shows a fondness of her by buying her treats and blushing when she's mentioned at certain situations if she's not around.
M.M. is seen to have a huge dislike towards Chrome and this could be because of her possible feelings towards Mukuro. She seems somewhat jealous of her and has been seen slapping her and calling her names on some occasions. But after the final battle with Byakuran, she told Chrome to stay away from Mukuro since he was a fearsome person, and she was concerned about it. This may mean she has some level of concern for Chrome. Chrome doesn't seem to show anger towards her, nor does she seem to hate her.
Regardless of her connection with Mukuro, he sees Chrome as an important friend and always treats her nicely, just like he does to the other Famiglia members. During the Arcobaleno Trials Arc, he even brought her some onigiri since he knew she didn't eat much at the base, which Chrome accepted. Chrome also sees Tsuna as her boss and likes him since he is the only one who believed and accepted her as his guardian at the Mist Ring Battle and granted him a kiss, much to his embarrassment and Gokudera's anger.I-Pin offers her a bun to eat, however, Chrome starts warming up to the generosity of others. She then begins to help Kyoko and Haru prepare dishes for the boys. She then ate dinner with them regularly. I-Pin is often encouraging her gently to be more sociable and accept other people's kindness. Now when she is usually seen, she is with either I-Pin, Kyoko, or Haru.
When Daemon, disguised as Julie Katou, first saw her, he had been taking a walk at Kokuyo Street and since then he had begun to stalk her, which Chrome never noticed. He had also secretly sent her a package of food after knowing that she had only been eating chocolate snacks. When he finally introduced himself to Chrome, he immediately confessed his love to her and asked her to go on a date with him after the Inheritance Ceremony was over and run away together with him. This was immediately refused by Chrome. After she was defeated along with Tsuna and the remaining guardians at the Inheritance Ceremony, he took her along with him, without her Vongola Ring. When she had woke up in his room, he flirtatiously offered her some dress and even offered her to help her change so they can "get to know each other well" and claimed that they are compatible to each other more than her and Mukuro. However, when he revealed his true identity, Daemon claimed that he intends to use Chrome as his tool to take over Mukuro's body. He is shown to be careless of her well being and sees her as a mere bait to lure out Mukuro as shown when he removed her illusionary organs and taunted her in order for Mukuro to come save her so he could fight him. Chrome herself also seems to dislike him much like the others, but after hearing his past and he dies, Chrome feels sorry and even cries for him as she comments that Daemon has finally found peace.
Appearance in other Media
She appear in the second volume of the Reborn! novel "Hidden Bullet: 2X-Fiamma," which explained how she first met Ken and Chikusa: Chrome, who was still known as Nagi at that time, just discharged from hospital and on her way to Kokuyo Land as instructed by Mukuro, met Ken at Namimori Park. Ken, who fell asleep after arguing with Chikusa and separated from him met Chrome when he realized that he had slept on her lap and then Chrome fed him an apple when he's hungry, which Ken tearfully ate. She also appeared in the fourth volume of the "Hidden Bullet" novel. She also appears as a main character in the Drama CD 'Chrome Saw it! Happy Day at Kokuyo Land' is where she meets Lambo, who sees her learning Italian and tries to teach her. Then, she meets Tsuna and after some events, Lambo spills the bucket of water that Chrome had brought from the bathhouse for Ken onto her. Tsuna offers to let her go to her house to dry her wet Kokuyo uniform and change into dry clothes. While she is changing, Ken and Chikusa suddenly arrive at Tsuna's house and much to Tsuna's protests, Ken keeps banging on the door of the room Chrome is in and tells her to come out. When Ken actually says 'the pineapple head inside', Chrome switches with Mukuro and the latter uses his First Realm on Ken. At the end of the day, Chrome heads back with Ken and Chikusa but not before Tsuna asks why Chrome is with those two. She states that it is because Mukuro told her to and because they were her first comrades and she trusted them.
