Youkai (EntityClass, 3)
From Compile Worlds
A youkai is, originally, the Japanese term for hideous monsters. But nowadays, very few people even believe in them in real life, so they've started to take refuge in places like Gensokyo and in scrolls and stories and fiction in general. So Touhou makes it nicer - they don't have to be hideous, and are basically anything in Gensokyo that isn't human. Even the ghosts are youkai, and let's not forget the ex-human who became a youkai from levelling up her magic over 9000.
They're really fond of eating humans. Well... the more savage ones, anyway. Some others are fond of eating normal food, fear, cucumbers, etc. Anyway, the more savage youkai in Gensokyo are kept in check because of Reimu Hakurei and her family of holy duty. And other exterminating people, too.

No more eating humans, and you can only use spell cards now.
