He works at the Fate Production Bureau, a place that manufactures doorknobs for the Dream Realm. The rabbit costume he wears isn't just a quirky outfit—it's actually functional, letting him move freely between subspace and the regular world.
He shows up pretty late in the series (Volume 31), but becomes surprisingly important to the story. His relationship with Shinobu starts simple enough: she finds him unconscious and starving on the street and shares food with him. That kindness sets everything in motion, and the two eventually end up together as a couple.
