Not that strange! Anime became mainstream recently yes but the community has been here for long. Usogui is a gem find but its not really obscure by those standards.
Appreciated though, I felt like Plato for a moment.
I'll admit I am not much of a fan of this arc. Been really enjoying this insane manga so far but now I feel it's just going through the motions of a final boss to let everyone shine and it's a bit draggy. Personal preference.
