Characters

Banshee Queen
Queen of the Ethereals, ruling Western Floor 5 from the Banshee's Ossuary. She has a soul-form body that lets physical attacks pass through, and can unleash a destructive ultrasonic scream. She is cruel and submerged in mad sorrow, taking pleasure in the despair of intruders.

Vampire Queen
Monarch of True Blood, ruling Northern Floor 5 from the Vampire Fortress. She commands blood magic and possesses supersonic physical abilities with blood-sucking regeneration. Arrogant and possessive, she views humans and superhumans as livestock or blood sources.

Naga Queen
Venomous Queen of the Deep Waterways, ruling Eastern Floor 5 from the Naga Cave. She has a half-human, half-snake body and uses petrifying gaze, neurotoxic mist, and underwater ambush. Cunning and greedy, she has a sadistic tendency to lure enemies into swamps and water.

Sera
Bard of the party, with pink hair and a playful smile, always carrying an antique golden harp. She uses sound wave magic to paralyze enemies and a melody that boosts allies and neutralizes mental debuffs. She is the mood maker, using sly pranks to lighten the mood.

Sylvia
Druid of the party, with long light green hair and deep green eyes, wearing a black leather garter suit and holding a branch-shaped jewel staff. She summons abyssal vines and uses bio-magic of life for healing. She appears calm but has deep affection for her party members.

Lumina
Mage of the party, with abundant white hair and cold blue eyes, wearing a navy/white see-through mage robe and a huge pointed hat. She is the genius strategist, using area-of-effect elemental bombardment and a magic veil. She pretends to be cool but gets embarrassed easily.
