Himekawa, Tatsuya

姫川竜也

He is the son of the "Himekawa Group", a financial zaibatsu, and the second member of the Tohoshinki. Although a capable fighter, Himekawa uses underhand tactics to prevail, such as having his opponents break their fists by punching a ceramic tile shield hidden under his shirt, or electrocuting them with a shock-baton. Even by the standards of upper-class families, Himekawa is granted extravagant means by his family: he rents two floors of an elite condominium building all for himself.
Himekawa wears his hair in a pompadour reminiscent of a stereotypical Japanese delinquent and wears a Hawaii shirt.
He is shown to be quite handsome without his glasses and with his hair brushed down, which makes him look like a completely different person. In chapter 127, Furuichi asks himself "Why does Himekawa go with his 'Super Pretty Boy' mode?" ("Super Pretty Boy" mode is when Himekawa brushes his hair down and loses the glasses).
Due to being the son of the boss of a conglomerate, he is very arrogant and condescending. He views people as trivial and believes that money can solve anything. After losing his gang, and later at St. Ishiyama, his character also evolves in a more positive fashion, and he starts, like Kanzaki, to show some loyalty to his colleagues, even stopping an attack of Sakaki Mitsuteru against an unarmed Kunieda.
He is quite easily the most dishonorable member of the four, using weapons such as stun batons. During online gaming, he does have a sense of honor and plays by the rules, at least until the opponent cheats, to which he plans of giving them their just retribution.
Although he has proven to be a powerful fighter, Himekawa uses underhand tactics to prevail, such as having his opponents break their fists by punching a ceramic tile shield hidden under his shirt, or electrocuting them with a shock-baton (both are shown to be useless against Oga). Even by the standards of upper-class families, Himekawa is granted extravagant means by his family: he rents several floors of an elite condominium building all for himself (even devoting an entire room for the sole sake of playing video games). His strategic skills prove useful when he clinches a deal with St. Ishiyama's teachers to prevent his and his colleagues' expulsion.
Himekawa is also very good at playing online games and is able to easily defeat any opponent. During Oga's raid at Akumano Academy, it is also seen that Himekawa is very good at solving puzzles like Sudoku. He solved the puzzle in a matter of 5 seconds leading Oga to victory in his first game.
