Characterized by a lavish outfit of layered sheer black, white, and wisteria-colored fabrics and an exquisite crown adorned with jewels.

Rem Ain: Half-human, half-demon male, child generation (18 years old). Dark gray hair, amber eyes. Wears a turquoise scarf, ash-brown travel gear, and carries a leather bag and maps.
