One of the main heroines of the story, she is the childhood friend of Takumi, and has been with him ever since they were both in the orphanage. She has a habit of meaning entirely the opposite of what she usually says, a fact only Takumi seems to be aware of. It was revealed that Takumi was the unwitting inspiration for this habit. She works at the Stray Cats as a part-time job. When she's angry, she tends to shout "Die twice already!" to the poor soul who incurred her wrath. In addition, Takumi (and occasionally Ieyasu) is the unfortunate recipient of much of her violent outbursts, ironically it being him who taught her that.
She has a crush on Takumi, and is frequently teased about it by her good friend, Kanae. She confesses to Takumi in a panic, and leaves Takumi somewhat hanging on the credibility of what she had said, stating both love and hate towards him. Fumino's parents died in an accident, leaving her orphaned. She is also shown to be extremely jealous when Takumi gets along well with other girls. She is easily embarrassed, and can get worked up if someone even suggests that she cares for them. To hide this, she normally comes up with unrealistic lies to hide her concern for anyone.
