This manga offers an intriguing deconstruction of the conventions of the mystery genre, along with a fascinating metanarrative that defies expectations. It's surprising to see how Kago explores these themes in the context of eroguro, a niche genre. However, the rest of the stories in the anthology can be more predictable, focusing mainly on the grotesque, disgusting and erotic. “Fraction” isn't for everyone, but for those interested in a unique and thought-provoking narrative experience, it's definitely worth exploring. It's a good option for mature readers who enjoy slow-paced, thought-provoking horror with a mix of dark mystery, graphic gore and a touch of twisted relief anddark comedy.
