DarkerTale (crossover fanfiction #1)

When Chara wakes up one day in a mysterious and completely new world, she has no idea that her fate is already sealed. To return to her own world, she must find seven pure hearts scattered across the entire realm. However, Chara's path is overshadowed by dark shadows, as ruthless individuals are also on the hunt for the pure hearts to destroy the world.

In the midst of these challenges, Chara faces a difficult decision: Should she embark on the quest for the hearts and save the world from impending doom, even if it means she can never return home? Or will she take the tempting path to rediscover her old life, without concern for the fate of this unfamiliar world?

The decision is in her hands, and the future of the entire world depends on her choice.
