The first volume sold me a dream, I ended up having a fever dream. As all the other said this manga is reaaallllyyy confusing and I had to reread some parts several times. BUT if you actually put in 100% of your brain power into reading this you get an amazing story about love. The plot is complemented by some of the greatest (no pun intended ) art I've seen in manga, Oh! great is able to show so much with about characters or a situation just through staging and it looks sooo good. Let's start with what I didn't like: I really wishe the story wasmore school life based and less importance was given to the Black caucasoid and the 21 stars because I didn't care all that much about those two big organisations. Especially ouranos that felt like a pretty basic but interesting character at first but I feel like he's losing his shit so often that he loses that cold manipulator aura and he just becomes a character with unclear motivations and personality.

Now let's see what I liked:

I think volume 1 is probably my favorite out of the bunch (tie with 10 maybe), the style was a blend of comedic dynamism and poetic scenery with some sci fi elements and an original power system. But what I loved the most was definetly the characters and the way their relationships were portrayed. I thought this would be an action shonen centered around love and relationships with down to earth characters and an intimate but absurd story. Then I was remembered that Oh great was working on this (even though he didn't write it) and remembered air gear's ending. Honestly I really wouldn't have minded if the story waes how i had described it above but I'm not dissatisfied with what we got neither.

My other favorite volume(s) would be the first back in the future arc (~volume 9 to 11) , I LOVED the characters dynamics in this arc. Like again this arc could've been a manga on its own. Loved the teenage summer vibes, the weird reversed time travel system, and most importantly: Fumiho. Like DAMN this arc really fleshed this kinda ideal/deus ex machina character into a real human feeling guilt, love and everything in between. A character who doesn't want to see another day but cannot die because she knows her loved one would give his life for her, so she instead decides to always repeat the past without being able to either make her lover not exist because she can't support a world without him or to love him for it would lean he would have to share her burden and therefore suffer as much as her.
Reading this arc after volumes of mecha soldiers fighting monsters nearly brought me to tears.

So to finish an extrimely intricate and original story with some killer art but some slower moments that I didn't like or felt too complex
