Decim

Decim tends the bar on the fifteenth floor of Quindecim, where he works as an arbiter deciding whether newly deceased guests are sent to reincarnation or to the void. Pale-skinned, white-haired and dressed in a formal vest and bow tie, he greets every visitor with the same detached courtesy, testing their character through seemingly ordinary games that gradually expose what they are hiding.

After five years on the job, Decim still struggles to read human feelings, but everything changes once an assistant known by the alias the black-haired woman starts working beside him. Watching her react to each guest teaches him to notice nuance he previously missed, and he comes to value her opinions even when they clash with his own judgments.

His calm rarely breaks, though it does when Chiyuki is threatened by the volatile arbiter Ginti, prompting Decim to fight back with the threads he otherwise uses only to restrain unruly guests. He answers to Nona, who oversees his experimental placement, and treats fellow arbiter Clavis with quiet respect.

Decim's growing capacity for empathy, sparked by his time with Chiyuki, sits at the center of Death Parade's exploration of what separates human judgment from mechanical process.
