Chen is a character of Touhou Project’s series. She is Yakumo Ran’s shikigami.
According to wiki, Chen was guarding the village of Mayohiga during the events of Perfect Cherry Blossom. Unfortunately, she could put up little resistance due to being far away from her master.
So Chen actually appear in many Tohou Project’s game and she is actually a bakeneko spesis (demon cat? I think?).
If I recall bakeneko is originally a cat that becomes youkai. They can be bad bakeneko or good bakeneko. But mostly we read in Japanese Manga is good bakeneko right?
