I am a person who was pulled by a gay friend to cosplay Dai-sensei Akutagawa, but I don't know the character at all. Originally this was not a big deal, but (happy to hear it) the sad thing is that I have traveled through time! A system told me that because I passed through the plane barrier and wanted to go back, I could only wear a vest and travel to other worlds to repair the plane wall, accumulate points and return to my world.
Me: OK! Let go!
Note: The protagonist does not care about the second dimension, so he does not know the plot. The vest used can treat them as people unrelated to the original owner. This is the first time the author has written an article, and the characters are extremely OOC!
Concept: Everyone can be light
