She and her daughter found Yuta Hibiki passed out in front of the Junk Shop and brought him inside to rest. Awakening Ever since then, she and her shop was frequently visited by the likes of the Gridman Alliance members and the Neon Genesis Junior High Students, since the old computer where Gridman resided, Junk, was located in her store.

  • Like most of the cast, her color scheme and design are inspired by a character from the Transformers franchise. She has a pattern on her apron that matches the pattern on the abdomen of the original incarnation of Megatron.
  • The earring on her left ear resembles Midori's third eye, from Space Patrol Luluco. A reference to her voice actresses' previous role.
