The Fool Night manga has been serialized in Shogakukan's Big Comic Superior since November 2022. 12 volumes have been released so far. VIZ Media is publishing the series in English and describes the plot:
Kamiya is at the end of his rope. His mother is ill, and his job barely pays for her medication, much less food. With few options left, he considers the life-changing process of transfloration. Ready to give his body up for a payday, Kamiya is about to explore the limits of society’s waning humanity.
