But, ironically, she doesn't want to lust or seduce after males. Therefore, Takehiko declare Shizuka as a Succubus Trap due to her somewhat masculine features, and promises not to let his libido get in the way. However, Shizuka declares a challenge to Takehiko: To not be perverted around her, or any other girls! And he's going to need all the help he can get, when a few other girls are attracted to him!
