Atsushi Otani (大谷敦士, Ōtani Atsushi)
Drama role by: Teppei Koike, Voiced by: Akira Nagata, Voice actor for game/drama CD: Takahiro Sakurai
Atsushi Ōtani is one of the main characters. He is very short for a boy, standing 156 centimetres (5 ft 1 in). The average height for a male in Japan is 171 cm (5 ft 7 in). Like Koizumi, Ōtani's surname (roughly, "big valley") is a pun on his diminutive stature, and he can be thoughtless and rude; at heart, however, he is kind and a little silly. Ōtani is also the star player of the school basketball team.
His ex-girlfriend is Mayu Kanzaki, the manager of his middle-school basketball team. She broke up with him for a much taller boyfriend, and this is one of the reasons Ōtani is sensitive about his height, but he later finds out that wasn't the reason she broke up with him, it was because she was in love with someone else already who just happened to be tall. He doesn't know quite yet how he feels about Risa, and only responds that he can't see her as a girlfriend (at the moment) when Risa confesses her feelings. But later, he realizes that he does care for her, and he kisses her. Later on in the series, Otani gets the wrong idea when Risa keep doing suspicious things with her co-worker Kohori, and then breaks up with her. However, after seeing how devoted she is to him, Otani reconsiders and they make up on Christmas Eve.
