[Obaka] Funky na Omatsuri no Manga

This manga is dumb, but to answer Go Hum Yai-chan's question, those guys told him that there was an erotic event with a cool, absent minded, pointy eared, silver haired, long lived creature. The ogre was told that there was some brilliant and sexy assassin. They meet each other, and get angry that they were tricked, but then the girl tells them that she's the one who matches all of those descriptions. She offers to make it erotic if they pay her, but they slap her for tricking them and just rape her instead. Kind of funny, because I'm not even sure if she intended to trick anyone. It seems like those guys just got their own ideas in their heads(They really expected Yor or Frieren? XD), and raped her because she didn't meet their crazy expectations.

What the fuck is happening
