Is the mc really going to be a submissive toward his sister and without the ability to do anything without his sister aproval?. I understand that he cares about her and all but she’s being naive and annoying, always eliminate all possible enemies or those that have a potential to be a danger to your person before they can grow and kill you later in the Future. The mc really needs to Make his own choices without being influenced or caring too much about his sister aproval or reactions toward his choices. At the end of the day he is the mc of the story and the one that’s protecting her.
Ok so all this trouble was for the MC to get Piyo's OPR device so that author can give us the "Oooh" "Aaaah" moments when he measures his opponent's Battle power. I can't help but wonder if there was better way for MC to get it without killing Piyo who gave us nerdy guy vibes. I mean he could've died as an accident or something.
Gonna be honest, at first I saw this book was like Warhammer so I was gonna read his other 2 books, but from the story & the comments the author liked I can tell he's biased towards liking Sakura characters, so if his other books are anything like this, good world ideas, bad side characters, bad MC's for being led by the leash
From the looks of it, either the little sister needs to change and adapt or she is going to get herself n the mc killed. Honestly, with the way the characters are acting now, it's easy to see this going into tragedy plot, with the sister dying coz of her stupidity or betraying the mc since he is a 'blood monster'.
