Kevin: Let me make a movie? And play Siegfried? Impossible, I'm not that kind of playboy.

Mei: I'm a scientist, I don't have the power of Mei Raiden, so I can't do anything.

Su: I have no objection to playing Walter Yang, but can you not make him go through so many life and death situations?

All in all, this is a story about traveling to the civilization before Honkai Impact 3rd and changing the future by making movies.

"So, traveler from another world, what kind of story will you bring to me♪"
