Story quality in the beginning is a bit iffy. It also feels lacking in direction, but it improves a lot later.Evil heartless MC, dark elements, some elements are especially morbid but not needlessly.As for the 5 stars, well I personally liked the quality and vibes it gives towards the end of volume 1. Of course some things could have been done better but whatever.Might not be for everyone but you never know, so give it a try.
