Ryuubi Gentoku claims descent or reincarnation from Liu Bei of Romance of the Three Kingdoms, driven by an unshakeable conviction in her destined world conquest. She relentlessly pursues a strategist to fulfill this ambition, identifying Takaaki Morokuzu as the reincarnation of Zhuge Liang (Shokatsu Koumei) based on name resemblance. She imposes a contract on Takaaki through coercive methods and physical persuasion, compelling his aid in her global domination schemes.

Long pink hair cascades to her waist, contrasting with piercing red eyes. Her demeanor is forceful and unyielding; she rejects any refusal of her demands. Tactics include invading Takaaki’s home and leveraging intimate advances to secure his cooperation. Despite this aggression, she operates communally, treating companions Unchō Kan'u and Ekitoku Chōhi as sisters. She insists on sharing all possessions—including romantic partners—with them and voices a specific ambition for motherhood, aiming to bear over 40 children while expecting her sisters’ aid in raising them.

Her bond with Kan'u and Chōhi underpins her actions; she involves them directly in recruiting and pressuring Takaaki, viewing collective effort as vital to world conquest. Setbacks only fuel her determination, escalating her measures to sustain momentum. Her dynamic with Takaaki shifts from initial coercion to an enforced partnership, maintained through strategic pressure and personal incentives.
