- Nicknames: BB, Blue Blood, Yen
- Age: ??? (physically in late 20’s)
- Gender/Pronouns: Genderless (they/it). Hard to pinpoint a sex as Uyen doesn’t allow anyone to touch them and they are practically a ghost to the legal system. Physically, they could be classified as a girl or boy as Uyen has a tall and thin figure, but facially they’re androgynous. No one dares to take it upon themself to search their genitalia, mainly because Uyen doesn’t allow it. Or maybe because Uyen is nothing but a void down there.

- Sexuality: ???
- Species: Between a pale crawler and just a creature. Classified as “experimental” and “exotic” in some medical books.
- Occupation: N/A
- Relationships: N/A
- Height: 6’11”
- Build: Very thin body, often slumped over. Super long legs. Spinal cord tends to show through skin and ribs are often exposed as Uyen strictly eats blue foods.

- Race/Ethnicity/Skin Color: Vietnamese, extremely pale with a cold undertone. The red that’s supposed to be in their cheeks from blood flow comes out as a frosty blue on their face.

- Hair: Naturally white and blue with visible frizz to it despite being straight. Fairly long as Uyen may use it as a shield to cover one’s body when bathing or being inspected.
