[Crossover] My Best Friends Are Everywhere

Blurb: Even today, whenever anyone so much as mentions Oshikawa Yuri, people can't help wearing the same complicated, knowing expression. It says it all: "Oh no, not again," "All right, what happened this time?" "Wait, why am I worrying myself over her?" "Why won't she just die already?"... It gives you a real stomachache. That girl... she stopped being "human" a long time ago. * No harem, no romance. The female lead is pretty overpowered. * Don't ask about updates, and we'll still be [bleep] friends.
