Birthday: November 23
Class: 2nd year student of Todo Academy
Known relatives: Takayanagi Dougen (father), Takayanagi Mitsuomi (brother)
He is the younger brother of Mitsuomi Takayanagi, but the two aren't on good terms. Masataka is your average high school student at first glance, but he is a surprisingly powerful martial artist. He is always a formidable fighter, but he becomes much more dangerous when he is serious or angered. He actually is easygoing and somewhat shy; however, his inner nature is perverted, even though he dislikes this part of himself. Masataka falls in love with Aya Natsume at first sight, but is disheartened when she falls in love with Souichiro Nagi instead. He has maintained a crush on her, yet is oblivious to the other girls who have a crush on him. After the incident at the bowling alley, he is greeted by some blushing girls from Todo Academy, he is seemly ignorant of their intentions.
Aya describes him as the calm surface that gently envelops the rapids.
Masataka is set up early as a great fighter, but is later ignored. At one point in the OVAs, Sōichirō refers to him as a supporting character. Despite being a great fighter, and one of the more powerful characters, Masataka is one of the most poorly treated characters. Because his elder brother is the president of the executive council, Masataka purposely joins the opposing Juken club.
Soon after he meets Aya for the first time and falls in love with her, Masataka and Maya Natsume come across Bob Makihara and Souichirou. Bob is amazed someone can make Souichirou seem so helpless in a one on one fight, as Masataka beats up on Souichirou. Angered by this, Masataka says for the first time he actually feels like beating up Souichirou, and does another KI attack. Souichirou distracts him by using his "barrier," where he shoves the unwanted bento Aya made for him in Masataka's face. Masataka attacks Souichirou in a berserker rage who gives him a severe beating.
