In this manga we have the story of a "Devil" a man that committed such heinous crimes (SA, extortion, extreme violence etc) in middle school and his life and the consequences after the fact. The manga tries to tackle the redeemability of such a person when they have lost their memories of these crimes and a story of penance with the guilt and weight of them.
The manga was interesting enough to finish reading online but after finishing it I cant say id recommend it. I feel like the story never really figures out where it wants to go and for the length of the story doesnt really have any redeeming pay off that its worth investing thought or time into. The psychology is very base level and the writing can be quite predictable and bad with the author often giving extremely obvious clues and repetitive storylines. I wouldnt say there was ever a "oh wow that was kinda cool" moment. The story just slogs on without any direction other that the overall plot of if the MC is worth forgiving. The ending feels extremely anti-climatic and gives you explanations and continuations to things you really dont care about.
The art is decently good and I do feel like it fits the story. The characters are okay but dont ever develop and I do feel like they were written from a extremely male perspective. There is multiple female characters that instantly fall in love with the MC even though he is a terrible person, and often times he has perpetrated crimes (especially of a sexual nature) against them. I also really didnt like the stories stance regarding the crimes and the forgiveness of them. I dont feel like the MC is ever forgivable and the way the story handles it borders on apologist BS. The story really seems to struggle with if we're supposed to like/forgive the MC or if we are supposed to be against him. Overall a depressing story with no real direction or payoff, I wouldnt recommend wasting your time with this one.
