Character Outline

Ryohei Sasagawa is Kyoko's older brother who is obsessed with boxing. 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 Tsuna and his friends doing something strange, he gets fired up and always wants to be a part of it. Due to Ryohei's enthusiasm, he often rushes into things without fully evaluating the situation, which often ends in his injury. He also has a short memory and forgets many important details, something his adult self solved by writing memo's. Ryohei is always hiding the truth of what he is doing from Kyoko due to an incident that happened when they were still in primary school. Some high school students who did not like Ryohei used Kyoko to lure him into a trap. In his attempt to rescue her, he suffered severe injuries, which resulted in the scar on his left temple. Kyoko still feels responsible for this incident though she accepts that he needs to fight. He is visibly concerned for Kyoko's safety, so he covers up his actual life-or-death battles with the cover story of "Sumo matches".

Abilities and Weapons

Ryohei is an excellent boxer who possesses great strength. 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. 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 unleash Maximum Cannon, a blow strong enough to destroy buildings. The attack works by concentrating all the energy in his arms cells into one punch. Thus Ryohei keeps his right fist in perfect condition, for times of great disadvantage.

Future Ryohei's fighting skills have greatly improved. He can now use Lussuria's footwork and with it multiply the number of blows dealt with a regular Maximum Cannon, an attack called Maximum Ingram. His Dying Will Flame is powerful enough to self-destruct active Box Weapons and also heal himself in a short time using the Sun activation.
