Akako Koizumi, a witch attending Kaito's school, is furious to discover that there's only one man in the world who can resist her charms: Kaitou Kid. It's Valentine's Day so all the girls in school are giving chocolates to boys they care about. Kaito notices a bunch of boys surrounding Akako and decides to ask her for a chocolate. Akako tells Kaito she'll give him one...if he throws away all of the others he's received. Kaito declines leading Akako to realize that since he managed to escape her charm, he must be the Kaitou Kid. Akako decides that if she can't have Kaito fall in love with her, then no one shall have him and plots Kid's demise on top of the Tokyo Sky Tree after a heist.
