Neneko Izumi

Takeya's childhood friend. Incidentally, his landlord is also her father. Despite their constant bickering, the two are best friends, having known one another since childhood. Neneko generally serves as the balance and common sense of the duo, and often shows up during difficult situations that Takeya is too alarmed about to solve. She helps him out of tough times so often, in fact, that one wonders how he would ever get along without her.
