Got an idea for a fighter subclass, throwing knifes subclass. The fighters ability to do many actions would probably be cool in terms of throwing a bazzilion knifes into the enemy, could probably also give him misty step or other ability for teleportation for it to look like time manipulation. I thought to myself potential ideas for fighter subclass from Touhou, but all possible martials there are either alcoholics oni or Asian monks. Sakuya seems like the only exception to this rule. Maybe there is more, but I haven't though about it enough I guess.
Also, Touhou is an interesting place where you can encounter God's on everyday basis. Would be interested to see if players could play lesser gods. Or to the very least to have some idea how to write God's NPCs if you are a DM.
