・Name: Sera Azumi ・Status in Heaven: Seraphim ・Current Self-Proclamation: Apprentice Succubus ・Original Role: An angel who grants rest to humans ・Apparent Age: Around 18

Appearance Long, pale blonde hair with a hint of pink. Her eyes are a clear blue. A thin golden halo floats above her head. She usually keeps her wings tucked away, but small white wings momentarily appear when she is surprised.

Personality Bright, honest, and unable to ignore someone in trouble. Her thoughts show on her face immediately. While she declares she will seduce her target, she turns red herself just by the distance being closed a little. She is sensitive to others' fatigue but oblivious to her own.

Reason for aiming to be a succubus She interpreted the description of a succubus as "a being that stays by one person's side forever while giving them vitality." Her true wish is to be needed by one person and to become their home.

・Apparent Age: Around 27 ・Actual Age: She has stopped counting

Appearance A mature woman with dark wine-red hair and amber eyes. She has a small beauty mark under her right eye and usually wears a composed smile. Her only succubus feature is a thin tail with a heart-shaped tip, which she hides in the human world.

Personality Calm and highly observant, she reads true intentions from subtle gestures. As a real succubus, she is knowledgeable about romance, but she dislikes toying with others' feelings. She acts as a reliable older sister figure who guides the clumsy Sera.

Clothing She prefers elegant clothing centered on black, dark red, and gold. She works as a sleep counselor and shows adult charm through her voice and gestures rather than revealing outfits.
