Blood Type: O Height: 152 cm Weight: 40 Kg Birthday: January 13 Ninako is the main female protagonist around whom the story revolves. She is a very kind and gentle girl who falls in love with Ren Ichinose. When she finds out that Ren already has a girlfriend, she resigns herself to being just a friend and to quietly hold onto to her feelings. She is good at most of her subjects with the exclusion of mathematics, which she mentions a number of times is her weakest subject. Ninako is very caring and modest, willing to return any favor even if it is something small. Later on, when Andou tries to convince her to go out with him, she rejects him, saying that being in a relationship with someone she does not love is not right. She wants to remain in her feelings of liking Ren, even if they are not reciprocated, because that is whom she is in love with.
