Tanabe has short, brown hair that spikes up a little, his eyes are also brown.
Tatsumi is depicted as the "typical 15 year old boy", excited about girls and sex. In his first appearance, he mistook the relationship of Jun and Tomo as a romantic one and is constantly asking Jun if they've "played sports that the opposite genders play with one another".
Tatsumi's initial depiction was that of a pervert, liking all girls equally. But his character soon settled over Mizusu as a crush.
Tatsumi isn't brave with his love either but shows it a lot and is frankly quite above-board so much so that Mizusu is well aware of this.
Tatsumi has had no personal character development as he is still a minor character and all his appearances have been about his crush on Mizusu
Tanabe is first seen as a male friend of Jun who is unusually interested in the relationship of Jun and Tomo.
Tanabe, in the dodge ball tournament, dedicated his play to Misuzu.
Mizusu confronted Tanabe whether he liker her or not and Tanabe said, "Yes" to which Mizusu said that Tanabe should grow a spine and do something about it already rather than rejecting him.
Tanabe got the girls a part time job at his family's ramen restaurant so Tomo could buy a gift for Jun's birthday.
Tanabe has succesfully traded contact info. with Misuzu.
