Sue belongs to a clan of vampiric beings who subsist on orange juice rather than blood. Her family teeters on exile after their patriarch failed to uphold their ancestral duty of instilling fear in humans. To reclaim their standing, he must now terrify 1,000 humans in the mortal realm. Amid this quest, Sue forms a forbidden bond with Kou, a human boy, sparking a resolve to abandon her lineage’s world permanently.

She sports blonde twintails, bright blue eyes, and pointed elf-like ears, her petite frame and youthful demeanor belying her age. Her deepening affection for Kou clashes with her family’s desperate mission, creating a rift that jeopardizes their chance at redemption.

The narrative remains focused on this central tension, with no expanded lore or supplementary media elaborating on her origins or future beyond this pivotal struggle.
