Kouhei was just developing feelings for his childhood friend Kurara when she went on vacation to Hawaii. On her return, she brought home a sexy new split personality, “Arisa.” Kouhei swore to stay by Kurara's side and protect her shocking secret – but just when he's growing accustomed to Arisa's antics, Kurara transforms into “Alice,” another personality!
Alice may look like Kurara on the outside, but on the inside she's a fourteen-year-old girl who's convinced that Kouhei is her tutor. Sounds simple enough, but there's a catch: It seems the only subject Alice is interested in is male anatomy. How in the world will Kouhei cope with this development? Plus – the origin of Kurara's split personalities is revealed, along with a fourth, deadly personality.
