尽田 那月

Reiya's neighbor who also works as a nurse. Very friendly and kind even helping a stranger like Reiya when he hurts himself. Even though Natsuki is laid back, friendly and a pervert, shows at time to be mature and wiser than she normally behaves.

 Admits that cheating is wrong but believes its a greater wrong to not take a chance at finding love/happiness an that she would expect the same of her partner if they are not in love. Also claims she doesn't have a relationship with just anyone. Use to have a good relationship with her boyfriend but he has grown distant after becoming addicted to eroge games. She makes Reiya question their relationship whether they are just sex friends or if he desires something more. Either way she seems content but leaves it to Reiya to decide what he wants.
