Hydra

Hydra is a nine-headed serpent-type monster engineered by the secret society 'Acastia.' Due to constraints in budget and development time, she can only summon four snake heads—each possessing its own independent consciousness—from a dimensional space behind her. Her core personality is gentle, soft-spoken, and polite; despite belonging to a villainous organization, she harbors no genuine malice. She is deeply devoted to colleagues such as Kuroitsu, and her earnest nature combined with limited combat ability often leaves her struggling during missions, revealing a remarkably human warmth.
