Makoto is a hardcore otaku who wears fashionable clothes and is very good at fighting and ero games.
In his childhood, he used to have a bald head. He also knew (and lived near) Saki Kasukabe. When he attended Shiiou University, he started dating her. Kousaka joined Genshiken the same year that Kanji Sasahara joined. He found a job as a programmer for an ero game company called Pushuke.
He is very fashionable despite being a hardcore otaku. He can be very blunt with his opinion, especially to Saki. He is very easy-going, smiles a lot, and and likes to try new things; he even crossplayed as a girl from Kujibiki Unbalance. He is a true dedicated otaku; he memorizes good techniques for all the video games he plays.
