[Western Crossover] Locked into the Villain's Faction

Tester Deloris entered World D-21, a superhero world filled with various superpowers, to check whether corrupted character cards could be restored and used again.

Wait, why have the cards from the good faction turned dark too?

Wait, why do the cards need time to load?

With a dark card in hand, Deloris is forced into an unbreakable bond with the villain faction in a superhero world. She's tired of it. If the world gets destroyed, she can just reset the timeline again.
