Tanaka has an obsession with cosplaying and making garage kits of plastic models.
He is the lone male member of Genshiken who likes to cosplay. Often times, he's in the clubroom building from a garage kit. He eventually dates Kanako Ohno, a fellow cosplayer. After graduating Shiiou University, he attends a fashion school in Ueno.
He is a very relaxed person who doesn't really bother people. He can be considered the normal, neutral person compared to the opposite extremes of the club (Madarame being the most loud to Kugayama being the most shy).
