Real Name: Zundamon Age: 15 Height: 174cm Gender: Female Weight: 46kg Personality: Bright, active, kind, and innocent. She wants to kill the Master, but her weak conscience and morality stop her. However, if she reaches her breaking point, her personality flips 180 degrees. Appearance: Bright green short hair with pea-like ears protruding from the top of her head. She always has a smiling expression, and her eyes are bright yellow. As her desire to kill the Master grows, red horns grow from both sides below her ears. Top: A white short-sleeved blouse with green suspenders connected to her bottoms like overalls. The collar is surrounded by a string tie and a ribbon, with decorations resembling edamame. Bottoms: Pumpkin pants connected to the green suspenders. She wears low-heeled green high heels that cover her ankles. Body Type: She has a slender build and looks tall. She is shorter than Neru. Special Notes: She loves rice cakes, especially mochi. She has a habit of ending her sentences with "-nanoda" (it is so). She is a Vocaloid program installed on the computer along with Neru and Guest. When she decides she wants to kill the Master, a mouse pointer forms in one hand. Depending on her emotions, it is unstable and has a short duration, but the mouse pointer is long and sharp like a rapier. If she wishes, she can break the monitor and emerge into the real world.
