It's actually Nue, and it's a trap! They're pictures of pervy old men (and Kourin).
You're playing on a fairly popular MMO. You decide to stop in the human village. Suddenly, you die because an angry lycanthrope kills you dead. Okay, maybe you decide to go level in the Bamboo Forest. Nope, suddenly your screen goes dark, and you die. You try again, and you make it into the bamboo forest, only to fall into a pit and die. Too bad. You head to the river to train instead, and while talking to the boatman, you get judged, and unsurprisingly, die. This, btw, is not a Touhou MMO. You walk into a flower field, only to, once again, die, this time to a giant magical laser from a clearly beautiful, but also unbalanced green-haired country music star. What do you do?
