Relentlessly Striving to Become a Cheat Ability [Western Crossover]

Every Overseer's job is to guard their own little world and keep it on its predetermined historical course. They watch coldly as its people cycle through life and death, struggle in the mire, rise through hardship, and fall amid the fires of war. But when a catastrophe capable of destroying the world arrives, even an Overseer cannot remain uninvolved. Newly appointed Overseer (land snake) Kalisa: Give it everything I've got!! Let's go, with the power of the world!!! But after Kalisa forcibly enters a little world and merges her will with it, she discovers that this world seems a little different from the others... ↓↓↓ Kalisa, turned into a six-year-old little runt by a weakened Gotham, stares up at the cat-eared man in front of her, dumbfounded. She swallows nervously, then tremblingly reaches for her brother, who is busy trying to steal the tires off the Batmobile. “Ja... Jason QAQ...” Turned into a sixteen-year-old girl by the vibrant Metropolis, Kalisa frantically steals kryptonite and hides it away, praying every day that Superman lives a little longer :) And yet... “Even so, I'm sorry, but I can't go home with you. My dad won't let me play with Superman.” Superman: “???” Turned into a twenty-three-year-old, youthful but beautiful Miss Peach by innocent yet powerful New York, Kalisa trembles and hugs her own weak, pitiful, and helpless self in the face of the Avengers Demolition Crew. But... “Never mind, it's fine. If all else fails, I can ask my dad, the richest man in Gotham, to fund rebuilding New York!!” New York's richest, Kalisa: “???” ***Reader's Guide*** 1.

The pairing is undecided. 3. I'll add more when I think of it.
