 Imadori is the class's number two pervert (the pervert ringleader being Ganji Nishimoto) earning him the nickname "Hummingbird".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 Mikoto and Lala; he continues to pursue them relentlessly, although they continually beat him up.
