(P.S.: Don't blame me for not warning you, this is poop. If you want to eat it, don't write a review.)
When you accidentally pick up a Rapeseed Flower Blade, you arrive in a Honkai world that hasn't collapsed yet, and your future destinies become intertwined, except that the way you open it is a bit strange.
(PS: There are tokusatsu elements and some character breakdowns. If you're interested, give it a try. If you're not, just leave. Anyway, I'm just doing this out of love and I won't get anything in return. No matter how much you complain, it won't affect me.)
