I don't mind turn-brain-off kinda works, but this one takes it to another level. There are really no stakes.
1st chapter, the MC, as a baby, basically floats in the air and goes: "Greetings, Mother." -- and nobody bats an eye. The parents just go: "Oh wow :O

"
And then, within a setting in which magic as a science is practically taboo, the MC constantly shows it off to....Everyone. Literally everyone, and nobody in the story tries to pin the MC as a devil or a living spirit, something, anything.
Basically, the MC constantly does stuff that
should warrant very extreme reactions, but instead, everyone just accepts it and go: "Oh wow, neat d:"
It could've been funny, if it was played upon...Like, the MC tries to have people take him seriously, but instead, everyone in the current era are airheaded idiots.
TLDR: mediocre story. MC is a reincarnation of a genius, acts like he's 40 years old know-it-all, and nobody questions anything he does. Worst of all, people mostly just talk about what they want to do, rather than just do it. Even for zombie-reading, it's pretty meh.
P.S: This is one of those manga, where I am
AMAZED it ever got adapted. I feel like even a non-pro version of any AI service could've produced the script for this. I always feel sorry for the artists who adapt this sort of shit.
