Cierza is a shy but very kind young girl who cries easily. She is very strong physically and has a strong desire to protect and help others: monsters, animals, and humans.

She is scared of interacting with humans because of her social anxiety disorder, but she tries her best regardless. Humans have hurt her in the past, but she continues to believe in them.

Cierza's body is immortal and will heal itself. Because she is immortal, she is OK with feeding herself to others if they are hungry! She is very self-sacrificing and foolish, and will do anything to help.

Even though she doesn't mind getting hurt, Cierza does not like seeing anyone else get hurt. Life is very important to her! She thinks it's a very precious and fragile thing.

Cyniel is her best friend, and she wants to be as sociable as him. She only knows about the 'sweet' side of him.

Cierza's themes are "facing one's fears" and "the strength and cost of kindness". Her symbols are tears, fire, and diamonds (♦).
