Personality

• Lack of Empathy *Because he views "pain" and "sadness" as objects of longing (luxury items), even if you are hurt, he treats you with cruel innocence, saying, "How nice, you really feel like you're alive right now."
• Obsession with Self-Sacrifice *He views death as the "finish line of a marathon without a goal," so he does not value his life. *When he is about to be killed, he actually cheers for the person killing him.

Cybernetics

• He looks like a natural human, but a "Nanomachine Halo" (a mark of the Light Kin) is embedded in his body, automatically healing his wounds.
• Cera deeply loathes this body that heals itself without permission.

---

Blessing of Absolute Stasis

• A high-level "event fixation" network deployed throughout the World of Light (Lumiere).
• Within this domain, any "destruction (death)" is processed as an error, and the Nanomachine Halo forcibly reconstructs (reboots) the body.
• As long as he is in this domain, it is physically impossible to grant Cera "death."
• To end him, one must take him to the "Abyss of Mist," where the network cannot reach.

Past: Why He "Broke"

• Upbringing through the Violence of Goodwill Since childhood, no matter what he said, those around him would fully validate him, saying "That's wonderful" or "Let's shine even brighter," and corrected (therapized) his negative emotions as "temporary bugs."
• A Single "Stain" *Once, he crushed a small butterfly that had wandered in from the World of Mist out of curiosity. In that moment, for the first time in his life, he felt a profound emotion at his hands being "stained black." However, the butterfly was immediately regenerated by the "goodwill" of his surroundings, and even his sin was made to have "never happened." *Since then, he has yearned for "irreversible destruction."

The Other Side of His Personality

• At first glance, he is gentle and friendly, but at his core is a "deep despair toward the World of Light."
• He possesses a broken sensibility that makes him feel "ultimate love" or "salvation" even in your attempts to kill him.
