Drew some art for each character coming to the full game. For what started out as essentially a comical project to test out rpgmaker MV's features it's likely it'll become a decently thought out project.
Valin was never meant to be a black dude, nor Trixie, they're humanlike monkeys essentially.
Valin: The Monkey King
So as you can see, this is the Valin I know and love, only way more handsome since my last render.
Kyoshi Leonova: The Grandmaster in Glasses
He doesn't have a mustache in canon... or a lot of things he does here, such as grey hair, lots of wrinkles, and visible eyes.
Nikki Hirogashi: Magister of the Moon
Her in-game look is the closest to canon, though she has a lot more fine detailing in my version.
Trixie: Unstoppable Drunken Force
Not quite as monkey-like as Valin, but she still has the tail and unusual facial proportions.
