I, Ralts, the Little Southern Belle

[Apocalypse + Pokemon + petite girl + transformation + prankster System + doing his best to resist becoming girly]

Su Ning, an overworked corporate drone, opened his eyes and found himself transformed into a mutant Ralts in an apocalyptic world!

The apocalypse would have been bad enough, but this Ralts also had an exquisitely cute appearance. Soft pink hair fell against his cheeks, his red eyes shone like jewels, and even his paws had pink pads. No matter how you looked at him, he seemed like a little girl who belonged in someone's arms.

But he's a guy! A guy! A man's man!

And the System was even more infuriating!

Other people's Systems either give them legendary gear or teach them martial arts. His [Pokemon (๑·̀ㅂ·́) ✧System (or so it claims)] was something else entirely: every mission had to involve some kind of joke, and it was dead set on turning Su Ning into a girl. It even played “Hachimi Song” on repeat as its notification sound, poisoning his ears. It was a complete prankster.

The humans wandering through the ruins were also starting to look at him in increasingly unsettling ways.

Zombies weren't scary, and human malice could be avoided. But being mistaken for a girl everywhere he went, and feeling so helpless that even his anger came out sounding like a coy pout, was what truly drove him crazy.

Su Ning roared at the air, but what came out was a sweet, girlish voice: “...I really don't want to be a girl, okay!”
