The plot is basically a reverse isekai where entities known as 'tsugai' can be used by humans to fight other superpowered beings. I know that sounds dumb but believe me when I say it's dope as fuck. I can't really say much else because not much else has been revealed. This series is still young, after all. But this is a hell of a beginning for a series that shows real promise and for any Arakawa fans, it's a can't miss.
