@Warui Yuugi Hoshiguma from Subterranean Animism, 3rd boss. There was this minor meme going around a bit earlier about the powerlevel of certain Touhous and Yuugi was said to be much more powerful than she appeared ingame because while fighting you her SAKE NOT EVEN DROP.
@Warui The ability of Yuugi's real meaning is“怪力乱神”, from direct translation, it is not "Power to control supernatural phenomena" . It is 怪=monstrous, 力=strength, 乱=terrify, 神= God. So she is really strong, likes Yuuka .
