[Anime Crossover] The Ultimate Su Mei

Twelve years of cringe-worthy history. Looking back now, I actually think it's pretty good... Maybe it's just because I haven't read much fiction in ages. First-person narration. The characters may go wildly out of character, so proceed with caution if that's a dealbreaker. "Thinking that Mary Sues and anti-Mary Sue stories can't coexist is just plain wrong." "Even if I succeed as someone chosen to fight against Mary Sues based on that mistaken belief, I'll probably just become the most powerful Mary Sue of all." "I'm writing this story with myself, someone who doesn't mind becoming a Mary Sue at all, as the protagonist..." "So basically, this is an anti-anti-Mary Sue story!"
