Osoroshii Koroshiya to Hirowareta Shoujo is a doujinshi made by the same author and illustrator of Sewayaki no Kitsune Senko-san. The characters are interesting, with a emotionally dead hitman and a little girl. However, there isn’t very much character development. However, this is expected of a short 13 chapter doujinshi. Overall, this is an okay manga. The story skips over a lot, but the story isn’t really the reason why you would read this manga. I recommend this to fans of Sewayaki no Kitsune Senko-San, as it has a similar level of cuteness, but with a lot more violence and blood.
