Maeda Hachibei is unlike most guys, who lust after gorgeous girls. This pervert lusts after their discrete parts, instead. When he moves to Tokyo to attend school, he finds himself living in a dormitory with five girls, each of which possesses one of the ideal physical features he desires: cat-like blue eyes, bullet-train breasts, a deep dulcet voice, straight "anime-esque" legs, or a waistline shaped like fine Japanese pottery. How can he manage to keep his wits when surrounded by these women? If you think this sounds like a Love Hina clone, you wouldn't be entirely incorrect but Hachibei is in no way like Keitaro.
