Summary
A brief description of the manga I’ve Been Mentally Fighting Against The Strongest Evil Spirit Ever Since Birth (Insane Advantage), So My Magic Power Ended Up Going Over The Measurable Limit ~The Possessed Child’s Modest Path to Supremacy~
A mental battle against the strongest evil spirit just five seconds after being born! …And while he was doing that, his magic power ended up getting maxed out?! Shirakami Kai was reincarnated into an alternate Japan where monsters known as “Spirit Fiends” exist.

“I’ve Been Mentally Fighting Against The Strongest Evil Spirit…..” TBH when I started reading the title I thought it was about marriage
i wouldn’t say its great but its slightly above most of the mediocre junk I’ve been reading so far. title is wack but up to ch 24 is decent enough.
The urge to add “insane advantage” to the title 💔
Jeezus f-cking christ mangaka or translator
, this deserves a 2-star just off of the dam title alone
.
Read upto latest chapter (21), the title is the most problematic so far. Like how do you even recommend this to someone? But nothing too bad its not overly generic reincarnated Op mc, but not to the level where he one shots every thing, still struggle against adults and such (as he should). The arts are an interesting power the art isnt terrible. So its 4 for me right now.
Pretty good read for something currently standing at a 3.7 rating.

Not worth reading.
Axed in chap 25, after having like 10 chapters about an unnecessary, uncharismatic stalker villain that added nothing to the story, but pad out time.
Sad, it had some fun elements, but it ended up going nowhere.
Adaptations are so cursed…
