Too soon for x-mas

It's the middle of October and Grim is very excited about the preparations for Halloween, but suddenly he has to go talk to the king of Halloween, King Pum, because Christmas preparations started appearing...

Grim, with his knight cosplay, will defend the honor of Halloween, and with his magic scythe, he will change the Christmas decorations for Halloween ones.

Cheer up, Grim!
