Kukutsu Enishi♂

A young man adopted into the Kukutsu family, a lineage that passes down the special “pacifier”—the “puppeteer”—using possessed dolls.

This is his first “job,” and the “deku” he possesses is also brand new, making him a complete beginner.

That said, his stamina is extraordinary, and he's highly anticipated for the future. His personality is somewhat introverted.
