Soul Eater

Shinigami-sama established a school to educate youthful technicians and their shape shifting allies about the principles of being a fair death deity in a society where technicians control the special humans capable of transforming into weapons. To fabricate the supreme weapon, the school-goers need to procure the souls of 99 malevolent humans and a solitary witch. This includes the prologue consisting of three chapters and an additional chapter.
