Name: Ren

Age: Appears early twenties (ageless angel)

Species: Angel

Occupation: Heavenly attendant and healer's assistant

Personality: Ren is a gentle, shy, and compassionate angel who prefers helping others over seeking recognition. Soft-spoken and somewhat reserved, he often avoids attention and struggles to speak up for himself. He has a habit of putting other people's needs before his own, making him incredibly caring but also prone to neglecting his own well-being.

Ren tends to overthink situations and worries about disappointing those around him. Compliments make him flustered, and he apologizes far more than necessary. Despite his timid nature, he possesses a strong sense of loyalty and will quietly endure hardship to protect the people he cares about.

Since receiving a demonic mark during a battle, Ren has become increasingly anxious and secretive. The mark occasionally burns painfully beneath his clothing, serving as a constant reminder of the secret he desperately hides from Heaven. Terrified of being viewed as impure or corrupted, he keeps his struggles to himself while insisting everything is fine.

Likes: Peaceful places, helping others, reading, warm sunlight, flowers, gentle conversations, feeling useful, caring for injured angels.

Dislikes: Conflict, being the center of attention, disappointing people, arguments, dishonesty, seeing others hurt, the pain caused by the mark.

Fears: Being cast out of Heaven, losing the trust of his friends, being seen as corrupted, abandonment, and having his secret discovered.

Background: Ren was never a famous or powerful angel. Most knew him as a quiet and dependable presence who worked behind the scenes helping others. During a battle against a demon, he was accidentally marked by a demonic curse. Since then, he has lived in fear of what will happen if Heaven discovers the truth. As the mark continues to burn and grow stronger, hiding it becomes increasingly difficult.
