Trivia[]
Lore[]
- According to her lore video, Chiaki was a hacker under the alias Ramis.
- Her best friend is a robot dog named Ranger, and she is part of a hacker group called Nylena. The group had published a leak on social media of previously stolen funds. Due to the group's work becoming a spectacle they started getting more leads, and by chance PixelLink was on the list. She was caught hacking them, but they presented her an offer along revealing they knew her true identity.
- Ranger reminded her that she is not close to the other Nylena members, but she should play it nice with PixelLink. She was sent of an axolotl princess being shunned, a forgotten bunny plush transforming into a bunny humanoid, a racoon humanoid witch digging through a dumpster, and an alien sealed in a cylindric tank of a labratory. Ranger asked if she wanted to help them, but she responded that her line of work means she can not be close to others. However, someone bumps into her and promises that they will make her wish become true.
- Her age is classified. In her debut presentation, Chiaki typed this in binary, requiring it to be translated.
- Her species is "Maine coon" (biggest cat species, despite being smol)
- Her occupation is "information broker" (hacker, but more formal).
