Weaboo friend roleplaying cringy anime character ruining my experience.

When I play DnD I play for the originality and to to get immersed the in world and the rich lore, especially to be racist against other races and classes.

I spent WEEKS fine crafting the most perfect lore accurate character only for my weaboo friend to come up with a an immersion-breakin, cringy ass, copy pasted loli girl from an Anime as his character.

Seriously, I thought playing DnD was free from this cancer until now whereI have to address his character by "MegUmI chaN KawAiI dEsu" or whatever they say in these chinese shows.
