I usually don't write reviews but damn this is so bad it deserves one.

Ok let's start. Imagine you are a teenager, a boy mid 15yo. You want to stand out, so you try the only thing you know it'll work: Being cool as heck.
Well, that teenager is the MC.

Here's the thing. This anime doesn't have a main plot. Yes, the MC wants revenge on all humanity but doesn't know how to achieve that and doesn't even think about it either. Well, maybe he does know, but the story is written so bad it relies constantly on the element of surprise.

A summary of the anime: Plot twist, Deux ex Machina, Pure Script power! The first 5 or so episodes ends with an imposible situation that makes you think "wow, how will they win?", but don't get distracted my fellow weeb friends, the answer will always be a secret power that kills everyone! And no, even if it happens in most anime plots, this time is ridiculous.

Again, the first half of this season is kinda good. First episode is amazing and traps you in, second is the same bullshit again, then the third again and the fourth, plot twist after plot twist... After that "cool battle" where the MC makes a bloodbath in a turn based fight, while soldiers brutally murders women, the MC and The Girl™ somewhat escapes from the Kingdom that controls the Whole World. The next episodes have the same structure: New Zone! Aw is deserted :c Haha look how cute is Doroka. Edgy monologue. War is bad. Doroka gets sad :c And repeat.
Some of those has more or less people, but you get the structure.
Then there is an absurd battle against one guy straight out of Cyberpunk but making less sense. Then there is the plot armor and an amazing power up!.... that feels completely useless because we've seen the MC decimating a whole city in episode 2.

So yeah, it doesn't make any sense. But lets talk about the sexism it has. The author seems that he doesn't speak that much to women, because wow: First there is Chloe. A strong woman that, after much adventuring, we don't see her powers. The she gets humiliated by striping her naked. We don't know much about her, just that she is used to give the MC a reason to do things. Another case of "the strongest being(male) gets his powers from the suffering of a woman".
Then we see every other woman get brutally murdered, or beaten after watching their personalities. While men are just Soldier A, B, C... Except Yamato and the king, whose death are cool too tbh.
And again, we have Doroka, a little girl that gets bullied by the MC but because of the Plot Armor™, she still sticks with him for a revenge she doesn't even want, but somehow end up romanticizing it.

So no, don't ask me what the anime is about because I still don't know. Maybe is revenge? Or a civil war? Or something with racism? Holocaust? Genocide? Everything? Idk man... Everyone looks bad, in every sense of the word.
