Tldr: author is milling this shit for money and to SA women every 3 chapters. Should've ended in High School.
Revenge manga like this should usually only be about a 100 chapters MAX. He's just stretching it.
The initial conflict was too "childish" to last more than 40 chapters. Cause MC and gramps could've just gone and killed the kids. Gramps especially. But nope. He wanted to train mc till he was in high school
(Which apparently is enough time for a minor to start a cult)
And now MC is fighting an entire cult as an adult becuase of shit that happened when he was 8.
If the cult was introduced from the beginning it would've been better.
Like check out "the devil returns to chool days" it executes a revenge on an organization really well.
But this manga is just an excuse to SA girls every 3 chapters and show the mc being fucking incompitent. Because how was the mc struggling so hard to kill 5 kids when he was trained for like 6 years by his super secret military grandpa.
Also the grandson getting kidnapped from the hospital pissed me off cause did they just release him??? Even with all the money in the world it would be hard to just take a comatose patient out of the hospital if you don't know them.
Sorry this turned into a long rant.
ikrr especially since the brother was severely injured and deformed, hospital staffs are extra precautious with people like that, like his death wasnt necessary. but even if we excuse those things, the highschool arc was good. but now its like an entire different story , like just end with the revenge already, revenge isnt the main theme anymore and its annoying
srsly the plot is getting too messy and unnecessary. this used to be hella good, but after mc grew up, its as if author is adding unnecessary stuff to prolong the story, idk maybe its necessary and im judging wrongly, but i used to be hella excited for this manga, now its just random shit happening and thats it, boring in my opinion
