Review Detail of kunichan in VENGEANCE OF THE RETURNER

i like the story from the beginning because it has a lot of potential to be great. mc is a dumb and a trusting and it is fine for me since other author tend to do it for Character development. It Started go haywire around 30+ Chapter that i was forced to drop it. suddenly killing innocent for no reason getting mad killing them and urging them to suicide. a sudden 180 degree turn around in attitude . i am not hook with the authors explanation since from the beginning he was introduced as a moraly upright person and it will take a lot for him to change like that . it was forced or the author lacked the right way to present to us readers that it does not click to me the right way and it irks me. Well according to his monologue he was told by the draconians that you gain power with contract souls . I cannot remember though it might be i have been skipping the other chapters since i am getting irritated to his stupidity or bored. Still i am putting this to library probably dropping it. reason? I am not quite sure how others see anti hero is but for me anti hero are those who still follow the HERO line but still has like a morality . it is hard to explain and there is a clear line for psychopath, psychotic or cold protagonist which i label them as Evil MC most of the time unless given an outstanding background or story execution. kudos though for very good world development and interesting way explaining the stats. there are other bad things such us being a little dumb, sudden change of mc attitude like being domineering as if he got mental issue. a little bit trusting and making very bad decisions. according to author this will improve and the product will be a cold hearted, vengeful and selfish protagonist . if that is your cup of tea i highly recommend it to you
