Flower Shop Kazami

It being a lonely flower shop that not even youkai patronized is already a thing of the past.

Thanks to the frequent visits of a certain beautiful puppeteer, nowadays it has grown to be an always busy shop that is the talk of the town.

It would seem that the customers today are a pair of cute sisters.
