Hanabichan ~The girl who popped out of the game world~ - S01

Musashi Shinonome, a recent college graduate, is visiting the Shitamachi God Heaven pachinko hall after inheriting it from his late grandfather. Inside, he finds a girl sleeping in a futon, who wakes up when he arrives. She introduces herself as Hanabi Hana Ariake: a self-proclaimed perfected pachislot machine that has turned into a human. To prove it, she shows him she can transform and shoot fireworks out of her body. Over the next few days, Musashi meets two of Ariake's human pachislot machine sisters: the energetic Versus Ikusa Takanawa and the loving Thunder Rai Nihonbashi. Now Musashi and the trio have to work together to make the grand reopening of Shitamachi God Heaven a success.
