I'm in a Crossover, and You're Telling Me This Is a Lostbelt?

I once led students in the Academy City uprising and overthrew Aleister's dark rule.

I once moved freely through spacequakes, making Westcott consider me his greatest enemy.

I once won the Holy Grail War and brought nuclear peace to Fuyuki.

As someone who transmigrated, I had reached the pinnacle of life!

Now, in a new Academy City, I planned to live as an ordinary person and enjoy the hard-won peace of everyday life.

Who could have guessed that Chaldea would claim this was a Lostbelt, responsible for bleaching the Earth white!

Faced with Gudako and a host of Chaldean Servants showing up at his door, transmigrator Kato Tetsuya was completely dumbfounded!

"Listen, this has nothing to do with me!"

Everyone from Chaldea: "Do you think we'd believe your nonsense?!"
