So first let me prefix this with while only one chapter is here, there is 16 on other sites. This is bad, he wants to live peacefully, but is a absolute moron. He never makes any attempt to learn about the world despite having multiple instances of someone who knows who he is and he could ask for all the info on a silver plater. He worries at first that someone would be able to detect him if he unsealed, which he quickly learned that the ability to do so is lost knowledge. The seals are just a problem with no benefit. Do to them he can't publicly show magic and he is discriminated against. Worse yet the seal dont even effect those who can sense magic auras. So they are totally pointless. He can freely erase them, but doesn't do so as he doesn't want anyone to know he can erase them if he gets attention. But he is a hidden disowned son who was exiled, no one knows who he is or could trace him back to the cursed child with two seals. At the point he realized they were a problem the only ones who know him Is his brother (who knows he is hiding his magic and wont tell) His sister (who he added a seal to) A Girl he saved (who knew who he was) The girls followers (who are so loyal to her they stayed in dragon breath without hesitation on her order) A small group of goblins (who cant even talk to anyone else as his magic barely let him) And a singular merchant. Just relocate to a further away counties and remove the seals and he would have no problems. But no its just another everyone hates him for having crests shtick. And that is just setting problems. Worse yet is that he isn't likeable, the seals he created somehow showed up on 70% of all living things, leading to massive discrimination and he just doesn't care at all, not even bothering to ask for any details about it. He also is very much willing to let others die to avoid showing his powers. There is little to no comedy, nor any stakes, just a op kid being discriminated against. Super short fights. With a serious tone.
If your into op power fantasies, put down and he just rolls over and takes it as he doesn't care, Were he thinks about out things, yet never does anything or takes any steps to prepare. It leaves me with the question, who is this for? what is the target audience? Just pass on this.
