Juuyou Sankounin Tantei Vol. 6

Model Kei Maneki was 5 years old when he first found a dead body in the woods and has developed a habit of discovering them over the intervening years. However, thanks to his relative ease with stumbling over corpses, Kei receives a degree of suspicion when called as a material witness, and it’s not unusual for him to wind up in handcuffs himself. Along with his model friends Itsuki and Simon who know he’s no killer, Kei sets out to investigate the crimes and clear his name, but little do they know that they’re about to become embroiled in a much bigger mystery.
