Koumakan=Reisen aka Gangsta's Paradise personified.
AI: Difficult / Powerful / Near Impossible
This character is quite literally the entire meme of "For her neutral special: she wields a gun" but multiplied by 30.
I believe she even has helpers from The Scarlet Devil Mansion, as well as being able to perform James Bond signature screen shot that does stun damage.
Be warned: Her 12th Palette is all of her skills, and she will take little to no damage in that form.
She is very stylish to watch fight and play as however. (I believe you can disable her AI in the CNS, but I forgot how to do that)
