Im talking early 20s at the time and they would cosplay and run around the local park in their outfits and had nothing to talk about besides anime and gaming.
one was like 21 and claimed she had a Japanese demon inside her and when she dies it will be unleashed and will destroy the earth. She would get pissed and yell dont make me let my demon out!
And some obese dude would ramble about how the only reason he hasnt killed anyone is because his two waifus from Naruto hold him back.
