This is likely an unreliable review as I only managed to get through two episodes. But the two episodes were enough for me personally.

The initial scene was relatively intriguing but the actions of our main made no sense from the get-go. Let's say he slaughtered everyone because he was trying to be completely obedient to what he was asked to do. Yet he makes a scene about his regret, and then manages to leave the organization by doing self harm. If those he assassinated were really that important to him to begin with, couldn't he have just done exactly this to prevent himself from being a part of the murders? He makes another scene about how his self harm is part of his redemption, yet when the pain flares up, he does everything he can to ease the pain. Then the odd transition of wearing some mask to disguise himself so he can just drink his life away and be a bum... is pretty distasteful.

Insert the female who starts a fight with him, after an odd and awkward obsession to communicate with a bum. As if she's a two-year old who has never seen bums before. The fight causes damage to the carts of innocent bystanders, and they just prance off as if they are supposed to be respectable good folks. Insert again, some wealthy kid who also just coincidentally happens to be obsessed with befriending the bum out of nowhere after having met him for two seconds. Only for his family to be slaughtered later and this bum just decides to watch for a while until suddenly trying to step in at the last second to be a savior. Insert yet again, the male companion of the aforementioned female. The fight scene between the two is a dramatized dance rather than an actual fight.

Yea... no matter how good the costuming or background is. There's nothing that can redeem these details in only the first two episodes.
