Nanami Momozono dreams of living an average school life just like any other high school girl does. Instead, she must cope up with the fact that her father, who is a constant gambler, has accumulated a bunch of gambling debts on her. As she can't afford to pay the rent, she gets kicked out of her apartment and is now homeless. Despite this unfortunate turn of events, she still maintains a kind heart. While sitting on a park bench collecting her thoughts, Nanami meets a strange man hanging from a tree because he is being chased by a dog. After saving him from the dog, she learns that the man's name is Mikage. Upon learning about Nanami's current situation, in a perfect example of how good deeds are rewarded, he gives her his home as a token of his gratitude. She accepts the offer because she is homeless. When Nanami arrives at Mikage's home, she is shocked to see that it is not a normal home but a shrine for worship.
