Notes:

"1 Majuu Serval-chan appeared"
Player character is Kaban-chan.
Anyway, this is a parody of Nekomata from the original Shin Megami Tensei on the Snes.
Also, original picture in the link is actually a picture where the eyes shine but I didn't upload it because I'm a noob and don't know how to upload animations from pixiv. XD
