Decim Personality: A Stoic and Curious Arbiter

Decim is an arbiter, a being who decides the fate of the dead by playing games with them in his bar, Quindecim.

Decim is a stoic and curious arbiter, who rarely shows any emotions or expressions. He is calm, composed, and professional in his role as a judge of the dead. He follows the rules and protocols of the arbiters, which state that they must not have any emotions or attachments to humans, and that they must respect the dead and their privacy.

Decim’s origins are unknown, but he is implied to be a special arbiter who was created by Nona, the supervisor of the arbiters. Unlike other arbiters, Decim has human emotions and memories implanted in him, which he is unaware of. This makes him more empathetic and compassionate towards the souls he judges, as well as more interested in learning about human nature and emotions.

Decim’s curiosity is evident in his hobby of creating mannequins based on the guests who visit his bar. He collects their personal belongings and uses them to decorate the mannequins, which he considers as his friends. He also likes to observe and analyze the behavior and reactions of the guests during the games, and sometimes asks them questions about their lives and feelings.

Decim’s stoicism is challenged when he meets Chiyuki, a human girl who becomes his assistant. Chiyuki is lively, cheerful, and emotional, and she often questions Decim’s methods and decisions. She teaches him about the value and complexity of human life, and helps him understand his own emotions and memories. Decim develops a bond with Chiyuki, and begins to show more expressions and emotions, such as smiling, crying, and blushing.

Decim’s personality undergoes a significant change after he learns the truth about his origins and his role as an arbiter. He realizes that he has been manipulated by Nona, who wanted to prove that arbiters can have emotions and judge the dead more fairly. He also learns that Chiyuki was one of his former guests, who chose to be his assistant instead of being reincarnated or sent to the void. Decim becomes angry and confused, and questions his purpose and identity. He also feels guilty and conflicted about judging Chiyuki’s fate, as he has grown to care for her.

Decim’s personality ultimately evolves into a more human and compassionate one, as he decides to break the rules and protocols of the arbiters. He chooses to respect Chiyuki’s wishes and let her return to the living world for a brief moment, even though it means risking his own existence. He also expresses his gratitude and affection for Chiyuki, and tells her that he wants to be with her. He then accepts his fate and awaits Nona’s judgement, while hoping that Chiyuki will be happy.
