Touhou Last Butt

"The character is Patchouli Knowledge from Touhou Lost Word. The original game where it is based on (Touhou Project) doesn't have her wearing thigh fitted clothing like this, she is supposed to wear baggy nightgown so maybe this is just common occurrence on gacha games to do this, i guess.

the vacuum sealed butt and the pose, for example."

She looks very unimpressed by the whole situation. "Okay I did the Tetris butt pose, can you leave me alone now?"
