An old man wrongly accused of groping ends up, before he knows it, in a mysterious temple with a suspicious goddess, together with a high school girl, Mizuki.

That's where he meets Fam, a beautiful dog-eared girl. Together with Fam, the old man steadily works as an adventurer, tackling dungeons and quests one step at a time...
