oh fuck off, OH great isn't even the author of this manga he is THE ARTIST and has had zero part in this story,
also if you still don't see that this whole series is an allegory for love and relationships you are dumb as a brick like holy shit, I keep seeing idiots constantly complain with speed reading and not understanding anything
also every single one of these abilities or concepts has already been explored, the power system isn't even as bad as series like freiren which literally makes shit up as they go yet no one complains about this, all of the mechanics of the fusion and physics are explained, even the roles of uranus necro maria etc
the entire point is the allegory of the states of matter and position of the universe is explored as "god" posing as an unaware school girl, which is a deconstruction of "
The Disappearance of Haruhi Suzumiya" but with sci fi battles(actually that series had that too)
this series clearly took reference to that, just like how chainsawman was a tribute or decontruction to dorohedoro, or Aldnoah.Zero for gundam or blue lock for giant killing or other sports series, or Bokurano for getter robo, berserk for devilman, vanguard for yugioh, pokemon for devil survivor, shadow star for stuff like gashbell, madoka magica for stuff like sailor moon or other magical shows. in some sense by taking some of its aesthetics and concepts and spining it a different way.
