我が家のヒメガミさまっ！

On the night of the summer festival, lightning struck the sacred tree at the shrine and a tiny girl appeared in the root, just like in Kaguya-hime. Takuya ended up taking care of her since she was quite attached to him. Afterwards, his miko classmate Shiori and famous swordswoman senpai Tsubaki declared that they will live with him too, and his osananajimi Kei seemed closer than before. Hime was actually the child of God and when she suddenly became an adult, it posed a ton of problems for him since she still acted like a kid. How is he supposed to treat her? Like his daughter? His classmate? Or the daughter of God?
