Bianchi is Hayato's half-sister; they share the same father. Bianchi, known as "Poison Scorpion Bianchi" in the Mafia underground, specializes in Poison Cooking, a technique that turns any food she makes into poison, regardless of whether or not it's intentional. Bianchi herself is immune to Poison Cooking and believes that she is quite an excellent cook. She is in love with Reborn, who was a former associate of hers, and wants to kill Tsuna to free up Reborn's schedule, though she refuses to kill him for the benefit of others.
Daily Life Arc
Bianchi is first introduced with her goal being to kill Tsuna to free Reborn of his responsibility to train him. She attempts to accomplish her goal by feeding Tsuna her special Poison Cooking. Over the course of the Arc, she lightens up on her attempts to kill and settles into a role where she causes comedic conflict. She perfects two new killing techniques in addition to her original one. She mistakes Adult Lambo as Romeo , almost killing Adult Lambo with her poison cooking. Romeo was her ex-boyfriend, who died due to an accident. Before Bianchi broke up with him, they had a horrible relationship and everytime when Bianchi thinks of him, she gets upset. Romeo's ghost tries to get revenge on Bianchi, but end up being defeated with her Poison Cooking (Anime only).
Kokuyo Land Invasion
Bianchi takes on her so-far most important role. She accompanies Tsuna, Takeshi, Hayato, and Reborn to Kokuyo Land to face off against Mukuro's group, after being worried over what may happen to Gokudera. She has her first and insofar only major battle against M.M. after Takeshi defeated Ken. Using her Poison Cooking to shield her from M.M's Burning Vibrato, Bianchi was able to get close enough to use Garden of Poison Varieties on her Clarinet, rendering it useless and causing M.M. to pass out from ingestion of the poison.
During their stand-off with Birds, she placates him by punching Tsuna, and thus filling his first condition, when Takeshi and Hayato refused, and stated that she is used to being hated. However, it is all a show for Birds, as she put hardly any force behind the punch.
Her final role during the Arc is being possessed by Mukuro along with Ken, Chikusa, and Hayato. Even after Tsuna gained the X-gloves and defeated Mukuro-Ken and Mukuro-Chikusa, he tried to use her and Hayato's body, anticipating that he would not use the same level of force against them. However, Tsuna ends up absorbing their attacks to expend the energy and knocks both unconscious.
In the Future, Bianchi had traveled with Fuuta in order to gather information, but later returns, revealing crucial information about the Millefiore. She trains Hayato to control the rings and boxes, but he later trains on his own. She has a Storm flame, and when she combines her box and ring, she is able to summon scorpions which emanate the Dying Will Flame, called Scorpione De Tempesta (Storm Scorpions).
During the Future Arc, Bianchi takes on the role of tutor to train Gokudera for the Melone Base Invasion. She is the one who gives him the Sistema C.A.I., at first to train with in the "Storm Room" Hayato's future self created. She taunts him about his illegitemacy through the initial Storm Room training, only later to reveal that she knew it would bring out the best in him. She tells her brother to try and destroy her Box Weapon Scorpions within the alloted time in a very low visibility setting. After the first session, Hayato does not return.
Bianchi again comes to the foreground as a tutor right before Choice, but this time to Chrome. They train in hand-to-hand combat, with I-Pin to help out. During the girls's strike, she supports Haru and Kyoko's decision to stop doing housework until the boys tell them what's going on. However, she also tells them what the boys are most likely thinking, and convinces them to call the strike off.
During Choice, she watches Tsuna, Gokudera, and Yamamoto battle Byakuran's underlings, along with everyone.
After Choice, she goes back to the base and retrieves something, revealed later to be the love letters sent by their father to Gokudera's mother. She is also the one who protects Haru and Kyoko from harm, and comforts them when Uni and Gamma sacrifice themselves.
After the final battle with Byakuran, she says goodbye to Haru and Kyoko, with the promise of giving a letter to Hana from Kyoko. She also finds Gokudera and reveals to him the truth about his mother and their father, using their father's love letters to his mother as proof, but Gokudera is resistant to her words.
