Daru captures random girl* who he’s convinced is Mayuri. She’s pretty sure she isn’t, and so Daru goes for the “love will conquer all” method of raping her until her memories come back, because she’s obviously been mind-hacked by SERN. Fat dude rape ensues. Consider it fair warning, for those who aren’t into that sort of thing.
*Forgive my lack of Steins Gate knowledge if there’s actually something important about the girl.
