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

Musashi Shinonome, a recent college graduate, inherits the Shitamachi God Heaven pachinko hall from his late grandfather. While visiting the place, he finds a girl asleep in a futon-she wakes up when he arrives. She calls herself Hanabi Hana Ariake, claiming to be a perfected pachislot machine that has taken human form. To convince him, she transforms and shoots fireworks from her body. In the days that follow, Musashi meets Ariake's two sisters, also human pachislot machines: the lively Versus Ikusa Takanawa and the affectionate Thunder Rai Nihonbashi. Together, Musashi and the trio must prepare for the grand reopening of Shitamachi God Heaven.
