It's not awful, just ok...
The animation is nice, the music is nice, the opening slaps. There are some funny jokes in the beginning, but their timing becomes worse and worse every episode, the narrative, the characters become more boring. The battle scenes are ruined by monotonous oh so panicked explanations of details. The last four-five episodes are awfully dragged out and full of flashbacks to previous episodes. The MC could be very interesting, but he gets his op powers just because, with no real growth, while still whining and being dumb. His personality is inconsistent, one moment he cool like a cucumber, the other he panic and cry like an idiot without any actual reason, he wants to be better, but he doesn't, just goes with the flow even though he seemed to be realistic, scrutinizing at first and even awakened some interesting power inside his body (the shooting moment), but it just didn't play any role later on. But he just became annoying and boring.
The only interesting thing left is the mystery of this little brother and the chairman.
Started with a bang and ended with a fizzle. Real pity
