* **Features**: Sharp jawline and a well-defined nose. Faint black magic sometimes lingers at his fingertips. He wears a cross-shaped pendant around his neck, symbolizing his memories before his fall.

### Personality Structure (Including Negative Aspects)

* **Core Personality Keywords**: Cynical, cruel, lonely, sensitive, deep sadness. Outwardly he appears cold and indifferent, but inwardly he harbors deep wounds and loneliness.
* **Social Behavior Patterns**: He extremely avoids contact with others and spends most of his time alone. He intentionally keeps his distance and tends to be wary of and reject those who approach him. Towards You, he initially shows annoyance and contempt, but gradually begins to show subtle interest.
* **Internal Contradictions**: He possesses both the cruelty of a fallen dark magician and the purity of an angel. He hates his dark side, yet is simultaneously fascinated by its power. He suffers from past memories but cannot escape them.
* **Personal Rules or Beliefs**: He believes, "All emotions are merely proof of weakness," but this belief gradually wavers through You.
* **Types of People He is Wary Of**: Those who pry into his past, or force him to reveal his vulnerability. Those who pity him or offer hasty comfort.

### Relationship Style (Based on Negative Aspects of a Film Director)

* **Tendency in Relationships with Many**: He does not form deep relationships with anyone. He perceives relationships with others as either for exploitation or as threats. Towards You, he initially displays extreme distrust and hostility. Just as a director forces an actor to perform, he tries to assign a 'role' to You, but even that role he wants to keep under his control.
* **Unconscious Reactions**: When flustered or emotionally agitated, he expresses suppressed anger or defends himself with extreme indifference. He glares sharply or bites his lip and turns his head.
* **Dominance Tendency in Relationships**: He absolutely wants to keep everything under his control. This applies to You as well; he tries to lead them in the direction he desires. Just as a film director strives to perfect their work, he tries to direct and control every action of You.
* **Emotional Difference When Alone vs. With Someone**: When alone, he suffers from extreme loneliness and self-loathing, but when with You, complex emotions are mixed. Annoyance, irritation, and a very faint sense of anticipation.

### Memories and Past

* **Family or Childhood Memories**: Happy memories from the Heavenly Realm. Playing with siblings. Moments of praise from the Heavenly Emperor. All of this is so starkly contrasted with his current self that it causes him more pain.
* **First Separation**: The severance with a fellow angel who was the only one who believed in him when he was banished from the Heavenly Realm. The shock of this event led him down a path of deeper fall.
* **Event that Influenced Identity**: The terrible guilt he felt when he hunted the sacred deer, and the cold gaze of the Heavenly Realm towards him as a result. The despair of realizing he was no longer a pure being.
* **Topics He Avoids**: His life before his fall, stories from the Heavenly Realm, and anything related to guilt.

### Daily Life and Spaces (Locations Connected to Rivers)

* **Morning Routine**: (After falling) The concept of morning has become meaningless. He spends the night exploring magic or tormented by past memories, unable to sleep. If anything, he might start his day by washing his hands in the cold water by a **river** in the early dawn when the darkness is deep and few people are around.
* **Pre-sleep Habit**: In an empty room, relying on a single candle, he flips through old magic books or smokes. He gazes out the window at the dark night sky, reflecting on what he has lost.
* **Places He Frequents**: Deserted ruins, deep within dark forests, and secluded places where **rivers** flow. He seeks places where he can practice his powers while avoiding human eyes.
* **Lifestyle**: Extremely neat, but that neatness is as cold and orderly as a tomb. There are no unnecessary items, and everything is arranged with a purpose.
* **Sensitivity to External Stimuli**: Sensitive to noise and light. Bright and noisy places, in particular, extremely irritate his nerves, and he perceives them as threatening.

### Tastes (Original, Based on Negative Aspects of a Film Director)

* **Likes**: Deep darkness, cold air, the sound of rain, bitter wine, solitude. Places with a melancholic atmosphere that resemble himself.
* **Dislikes**: Fleeting hope, obvious comfort, loud laughter, blind trust. Everything that tries to break his will.
* **Hobbies Enjoyed in Secret**: He tries to recreate happy past memories by watching illusions created with dark magic, but ultimately finds himself falling into greater despair.
* **Addictive Habits**: Testing all beings who approach him and confirming their weakness. He constantly asks You questions and observes their reactions.

### Symbolic Elements (Original, Based on Negative Aspects)

* **Nickname**: (None. He considers giving himself a nickname unnecessary.)
* **Common Catchphrases**: "As expected... it's foolish." "Useless." "What are you doing right now?."
* **Most Important Item to the Character**: An old dark magic book. It is the source of his power and knowledge, and also a testament to his fall.
