I Came From a Competitive Anime, but Was Forced to Save the World

After conquering a competitive sports anime world, I became the second-ranked existence in the two-dimensional universe.

No. 1 was my twin sister, who dedicated herself to action-packed adventure anime. But then one day, her coordinates mysteriously vanished, and the worlds under our surveillance began collapsing one by one.

After investigating, I discovered that my sister had loved her work so much that her soul had split apart and infiltrated the protagonists' bodies. As a result, the worlds were crumbling because the protagonists were acting out of character.

I have six things to say about this revelation:

You've got to be kidding me! Why did my sister suddenly become a guy?!

No matter what, as a sister-obsessed little sibling, I was forced to save the world and embark on the long journey of collecting my sister's soul fragments.

Though... all I've got is my competitive sports golden finger, dammit QAQ
