Baffled by the fact that the girl in the photo is Raku's fiancée, the aforementioned girl transfers in Raku's class as Marika Tachibana, the daughter of the police chief. She also bears a key that may unlock Raku's locket. Marika and Raku then head on a date, with Kosaki, Ruri, Seishiro and Chitoge spying on them. During their date, Marika bribes Raku into ending his relationship with Chitoge in exchange for answering all his questions regarding the girl and the promise he made ten years ago. Raku refuses, furthermore adding that he has no past memories with Marika, inciting within Marika her vulgar persona and bursts into a tantrum, causing Raku to finally recognize Marika.
