/jp/ - Otaku Culture

No.
Here's top 50 from the last thwiki popularity poll. 95% of the fanbase fap to these 50 2hus.

Green - canonically do not eat people. And I mean never eat people, be they from human village or outsiders. These are humans themselves, gods, fairies and all non human eating type of youkai.
Yellow - no info. But still most likely they do not eat people. For example Okuu: why would a human eating youkai live in a place where there is no people at all?
Red - a human eater. And even then Remilia just drinks blood and leaves her prey alive. And Flan just gets her blood from somewhere. It's not necessary to kill a person to get portion of its blood.
In the end there are only 2 touhous (Rumia and Mystia) out of 50 who eat people. Just mere 4%. Gensokyo is more safe than your average american big city.
