Profile

Ryohei Sasagawa (笹川 了平, Sasagawa Ryōhei) 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 memos. 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."
