When a Wizard Has Guardian Characters

(My private settings are as numerous as mountains!!!)

Matsuda Chinatsu always thought that Guardian Character owners were extremely rare, until she returned to Japan.

Various ten-centimeter little figures appeared one after another, making Matsuda Chinatsu question her life — when did Guardian Characters become so widespread in Japan?

So what about those days when she hadn't seen other Guardian Characters, doubted she was hallucinating, and almost became introverted? What was all that for, huh?!

(PS: Primarily focuses on Shugo Chara!, integrating parts of Detective Conan's Police Academy Five and HP content.)
