Character outline[]


As the older brother of Kyoko, Ryohei looks noticeably different compared to his sister. He is a teenager with tanned skin, gray eyes, and white hair. As a child, he received a scar on his left temple after an accident in primary school.

The most recurring outfit of Ryohei is his Namimori Junior High uniform. He wears a black sweater, with a white formal shirt underneath, and gray pants.

Ryohei's most defining traits are his adhesive bandage on his nose, and the sports tape around his arms.


His motto is to live "to the extreme!", which he applies to everything he does. As such, he prefers to fight his opponents head on, seeing any disadvantage as a chance to improve his fighting skills. He even barged into a zoo, expecting to fight a bear, but ended up fighting a lion instead. Every time he sees Tsunayoshi Sawada and his friends doing something strange, he gets riled up and wants to be a part of it. Due to Ryohei's enthusiasm, he often rushes into things without fully evaluating the situation, which often results in his injury. He also has a short memory and forgets many important details, something his future-self overcame by writing memos.

Ryohei is a very loyal person, especially to his friends. Without thinking twice, he will protect his friends in need and never hesitate to go full-out in order to protect them.

He has a soft spot for girls and children. He stated that girls and children shouldn't allowed to participate in battle, as he never agree to bring his sister Kyoko, Haru Miura, and I-Pin to battlefield during the Choice Game. During the Future Final Battle Arc, he volunteered to watch over Lambo so he could protect him whenever the situation becomes tough. His future self seems understand how to make children happy, as he gave I-Pin a doll that resembles her master, Fon and a lollipop for Lambo.

After becoming a mafia for ten years, Ryohei noticeably become maturer than her younger self. Unlike his younger self, the older Ryohei is much less reckless and could discuss a serious matter with cool head.

Weapons and Abilities[]

Ryohei is an excellent boxer who possesses great strength, always training nonstop and wanting to improve his skills as a boxer, and fight against opponents that has an extreme spirit, like Tsuna does in Dying Will Mode. His boxing training resulted in his proficiency in hand-to-hand combat, and ability to take and give a huge amount of physical punishment. Even the Dying Will Bullet, which increases a person's strength by removing the body's limiters, has no effect on him since he always lives "to the extreme".

Despite his nonstop training, Ryohei is considered to be one of Tsuna's weaker Guardians. During the Daily Life Arc, Ryohei was easily bested by Dying Will Mode Tsuna, despite using the same form as the latter. During the Kokuyo Arc, Ryohei was severely injured after an encounter with Ken Joshima. At the beginning of the Varia Arc, both Reborn and Colonnello state that Ryohei is weakest member of Tsuna's family. However, Colonnello was somewhat impressed by Ryohei and believed that if he trained him, the boxer could defeat the Guardians. Since he already has enough power to begin with, Colonnello forces Ryohei to rest for two days in order to replenish the cells in his body, since he frequently abuses them in his training. Colonnello explains that Ryohei's cells have a unique elasticity and tenderness that only one in a million people possess. During Ryohei's training, Colonnello shot him with a spiritually condensed bullet that risked death. By surviving, Ryohei's potential was unlocked, enabling him to create the Maximum Cannon attack; using his right foot as the trigger and compressing the energy of his cells into his fist, Ryohei becomes capable superhuman feats of strength, such as destroying a large boulder in a single punch.

Unfortunately, even though he's strong physically and mentally, Ryohei's tendency to act first before thinking sometimes gets him into trouble as enemies usually takes advantage of it. This one weakness is overcame by Future Ryohei, having more matured, is looking at the situation first before jumping into action.


Maximum Cannon

  • Boxing: Ryohei uses boxing techniques to perform his other techniques.

  • Maximum Combination: A high speed range of punches using both arms. While it is not as strong as other attacks, it is almost impossible to dodge.

Once released, it takes the form of a burning sun, with solar flares coming out of it, and then it shoots in a direct blast that destroys anything it touches.
  • Sunshine Straight: Ryohei lands a straight on the target powered up by 20% of the Sun Flames of his Cambio Forma Version X.
  • Sunshine Uppercut: A powerful uppercut that can be powered up when more damage is taken prior to usage. Similar to Sunshine Counter, it creates the sun like figure and releases the blast, this time, raising instead


  • Vongola Sun Ring: Won during the Sun Ring Battle. As part of the Tri-Ni-Set it is classed as S-rank. Ryohei is capable of releasing Sun Dying Will Flames from his Ring and use its Activation ability to speed up the natural healing process. Even though the Sun Flame is traditionally used for healing Ryohei has been shown to release them in massive amounts that overpower enemies. The Vongola Rings were later granted their true forms by the Vongola Primo; however, they were later broken by the Simon Famiglia.
