Call Me by No Name

Eichi University student Megumi Yotsugi meets Kotoha Furuhashi, a beautiful girl who was abandoned at the garbage dump. After visiting Kotoha's mysterious home, Megumi decides that she wants to be her friend, but she is flat-out rejected. Later, she learns that Kotoha is an alias. Thus, Kotoha replies with another suggestion: be my girlfriend until you guess my name. Then, during their temporary relationship, if she guesses her real name, they'll become friends—a strange bet. Megumi, unable to say no to the bet, deepens her relationship with Kotoha as her girlfriend. However, the past hidden in her name begins to bare its fangs.
