Delico's Nursery: Ikuji Nisshi

A string of vampire murders leaves behind references to TRUMP, the legendary first vampire said to possess eternal life. Dali Delico is ordered to investigate, but he accepts only under one unusual condition: his fellow agents must bring their children to work, and the investigation will operate out of his nursery.

The headquarters becomes “Delico's Nursery,” where four aristocrats accustomed to leaving childcare to servants must balance pursuing the Pendulum organization with feeding, calming, and protecting their children. Between Dali's exhaustion from caring for baby Ul alone, Raphael's jealousy, and disturbing symptoms appearing in Theodore, the fathers discover that understanding their children may be inseparable from understanding the case they are chasing.
