Nazo no Kanojo X (謎の彼女X)
First encounters are always memorable because regardless of the outcome, new experiences are sure to happen. For Akira Tsubaki, a young boy who knows next to nothing about girls, and new transfer student Mikoto Urabe, a mysterious girl who wears a cold facade, their first encounter takes a turn for the romantic. Through a series of strange events, Tsubaki suddenly falls in love with Urabe, and together they develop a curious bond. Thus begins the romance and mystery of Urabe, a girl who seems to have a unique way of expressing her emotions. [Written by MAL Rewrite]
