- Loves to enter in free-for-all arena fights.
- Her katana holster is her hair.
- Her people are those who worship and love any and all circuitry/electricity, which is why they get tattoos of lines like those.
- The filled in dots represent that which is controlled by the right side of the brain, the empty circles vice-versa. They are natural marks.
- 0723's missing (?) partner who went by the name "Quartet Jester"; Jes for short. Her reasons for disappearing are unknown to anyone but Queen, but the trust they share between one another is strong. 20 years old and loves root beer.
