This isn’t your average high-school sleuth, though-because he comes back to life every time he’s killed! Being a little too familiar with death and always awakening to Lilithea by his side, Sakuya’s happy to take on low-risk cases. Surely investigating a movie producer’s affair on a luxury cruise ship won’t pose any real threat! But when the duo ends up entangled in a larger and bloodier situation, Sakuya will have to get to the bottom of the mystery…and die trying! Source: Official Website, KADOKAWA stream
