You know, I honestly saw potential in the kid who was pushed in front of a car, how he could have actually repented and realized the person he looked up to sees him as nothing. Hell, he could have just been a good kid who was in the wrong crowd and realized that. He even had a love interest, despite the crude form of love he holds. Gotta show off how much of a degenerate he is after all. Can't have decent characters because mc needs new dummies to test his torture devices on. Which makes me wonder why the whole probing for repentance thing was even mentioned when it was only done once and no other time.
Where does he even get these devices he use to torture people? the literal torture cult the main antagonist runs doesn't even use medieval torture machines. Does their home depot just have a bonus section? Does the local fisherman just bulksell boxer shrimps? His grandpa was a soldier, not a torture device collector last time i checked.
And I love how after hearing about a sex traffiker with I don't know how many guards gets taken down by one kid, the bullies were like "yeah, let's fight him one v one, that'll turn out well!". Instead of leaving the city or something. Now that I think about it if one of them just left the city over the four years MC's revenge plot would be like, 9x harder. Watch him still have a medieval torture device and lug it all the way to Hokaido or something lol. The only reason he's even able to find the torture cult is because they're so famous.
And a torture cult can totally have a spotless track record for four years and keep growing when their members disappear regularly and they execute their own members in front of civilian members. no deserters or people who call the police here they all die too even though there's probably witness protection that can happen, or fleeing the city. Speaking of, the police and witnesses here feel especially stupid. Yeah, nobody report to the teacher or police and have the kid who rapes people in the changing rooms arrested. Anonymous tips are not a thing. Yeah, let's go check out the hide out of a suspected killer with no weapons or backup. Twice. Yeah, let's not monitor/surround the building that holds a suspected murderer giving him ample room to run away if he wasn't paralyzed in shock. Nobody just notices any of the cultists escaping i guess.
Oh, and one final note, the murder association the mc joins after jailtime. What if someone just, phones in an assassination on an innocent person and plants evidence. They just buy the victim's stories as is and it turns out to be true.
