Kusanagi Godou just wanted to have the quiet, peaceful life he didn't manage to get in his past world. But who was he kidding? When there was a Dungeon full of monsters, beautiful goddesses, and animal-girls, there was no way that was going to happen. Still, the Gods here were way more friendly than the Gods he'd met in the past. Maybe just a little too friendly.

Kusanagi Godou and his little sister, Shizuka, are orphaned after the death of their grandfather, but as fate should have it, the two end up in the Familia of a most unusual Goddess. But with the magical blessing granted by their new mother, will the children find themselves gathering more attention than they can handle?
