“When I grow up, I’m going to be your bride, Mune-chan.”, with those words, his first love moved overseas. Unable to forget her, Munenori became a university student, and he's miraculously reunited with her at university! But the girl who came back is a hardcore, gambling-obsessed gal!? Even so, Munenori still sees traces of the little girl she used to be, and gets swept along by her free-spirited ways. A slightly unusual college life begins, with Munenori and his friends caught up in it too!

The story of the series follows Hanabi, a pachislot machine granted human form, and her two friends, Versus and Thunder V, as they work at the Shitamachi God Heaven gambling hall in downtown Tokyo.
