Appearance
Clavis is a young man who always has his eyes closed and is never seen without a smile on his face. He has a spiky green hair with a streak of yellow color on the left side of his bangs. In the back, a light pink sidecut is visible on both sides of his head. He also has piercings on his right ear and nose.

His uniform consists of a light brown coat with dark brown collar and cuffs atop a white shirt and red tie. Additionally, his coat has two columns of yellow buttons, and yellow hemlines patterned before the cuff. He wears gloves and places his pin on the left side of his collar. On the bottom, he dons brown pants and a pair of black leather shoes.

Personality
Clavis is a mysterious young man but always acts amiably and serves with a smile. He often teases and makes fun of Ginti.

Plot
He appeared in episodes 1 and 2 as the elevator operator that takes Nona and Chiyuki to Quindecim and asks Nona what she thinks about Chiyuki's abilities as an arbiter's assistant.

He also makes an appearance in episode 5 transporting Nona to Quindecim where he greets decim and tells Ginti not to bother Decim as he has his own way of doing things. He makes a cameo in episode 6 as he watches Harada's impromptu concert with Chiyuki, Decim, Ginti, and Mayu. He makes another appearance in episode 10 where Oculus asks for his assistance only to use his beard to wrap around Clavis's head to receive his memories, where he learns Decim is an arbiter that Nona implanted with memories.

Relationships

 * Nona: The two seem to be on friendly terms and Nona seems to trust him as he is aware Decim is an arbiter with human emotions despite the fact that Nona has hidden this from everyone else, possibly meaning she trusts him. Unfortunately, Oculus used this to his advantage as he was able to read Clavis's mind to find out what Nona was hiding from him.
 * Decim: The two seem to have a good relationship as the two both greet each other politely and seem friendly to each other. Clavis also stood up for Decim against Ginti, saying Ginti should leave him alone because he has his own way of doing things.
 * Oculus: He seems to respect Oculus as his superior.
 * Ginti: Clavis loves to tease Ginti as he knows Giniti has a volatile attitude but also tells him to leave Decim alone. Despite this he seemed to be able to tell when ginti was genuinely upset, as in episode 12 when he asked where memine was and ginti said memine doesn't come round anymore, clavis sat down at the bar and requested a drink, while seeming a little more serious than he usually is.
