Fumino is 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 just so she could be with Takumi even after he was adopted by Otome.
When she's angry, she tends to shout "Die twice!" (or occasionally, "Die ten thousand times!") 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 also beats up Takumi when the two of them end up in close proximity with each other by accident, out of embarrassment. As such, her behavior resembles a typical tsundere.
