Villhaze acts as personal maid and bodyguard to Terakomari Gandesblood, an assignment stemming from Terakomari's status as a Crimson Lord in the Mulnite Imperial Army. During her academy years, Villhaze suffered severe bullying until Terakomari intervened and defended her. This act, despite Terakomari later facing bullying herself, fostered Villhaze's deep admiration and devotion. Villhaze later felt guilt over Terakomari becoming a shut-in, motivating her lifelong dedication to Terakomari's service and confidence restoration. Her personality is playful and flirtatious. She frequently seeks physical contact with Terakomari, such as sleeping naked in her bed to be the first person Terakomari sees upon waking. She makes suggestive remarks, demanding repayment "with her body" during baths and requesting contract amendments through kisses. These behaviors often escalate into actions Terakomari perceives as harassment, earning Villhaze the nickname "Pervy Maid." Concurrently, Villhaze displays intense possessiveness and jealousy towards others interacting closely with Terakomari, reacting with distress or hostility to rivals. She threatens individuals who consume Terakomari's blood and collects merchandise featuring Terakomari's image, once stating she would steal Terakomari's undergarments if dismissed. Professionally, Villhaze holds the rank of Junior Lieutenant in the Mulnite Imperial Army's third division. Her combat abilities center on poison mastery, including undetectable contamination of food or beverages and wielding poison daggers that dissolve targets on contact. Her unique power, Core Implosion, allows her to perceive the future of anyone who ingests her blood. This ability proved pivotal when Terakomari consumed her blood during a crisis, unlocking Terakomari's latent powers. Villhaze's relationship with Terakomari evolved from initial wariness to profound loyalty. After Millicent Bluenight abducted Villhaze to provoke Terakomari, Terakomari sustained severe injuries rescuing her. In response, Villhaze offered her blood, enabling Terakomari's power activation during the confrontation. This solidified Villhaze's commitment, culminating in a romantic confession and a vow to ensure Terakomari's happiness, expressed further in a love letter. Their dynamic includes moments where Villhaze interprets Terakomari's requests for her continued presence as accidental marriage proposals, highlighting the complexity of their bond amid ongoing tensions over Villhaze's persistent advances.
