Імадорі Кьосуке

Imadori is the class's number two pervert (the pervert ringleader being Ganji Nishimoto). He has the special skill of knowing a girl's bra size just by looking at her chest. Interested only in girls with breast sizes of D or larger, the main targets of his flirting are the well-endowed Mikoto Suo and Lala Gonzalez, and he continues to pursue them constantly although they are strong enough to beat him down. Imadori has some physical abilities, such as being strong enough to grapple Hanai to a standstill. He works in a hair salon called "Now Bird", which his family owns. He enjoys the tokusatsu show "Hatenkou Robo Dozibiron" (a Super Sentai/Power Rangers parody).

Despite constantly avoiding any involvement with Ichijou, he sometimes shows some interest in her, such as when he was admiring her singing during the cultural festival party, or cares about her, because he saved her from a night club from Suzuki. He also has a more sensitive side to him, which he shows towards Lala when he tries to get her to smile at her part-time job, even at the cost of getting walloped by her.
