She has pink eyes and long white hair with tinges of black and a black feather on the top, as well as pointed ears that also has a similar tinge in the tips and beauty marks under both her eyes.

On 2 January 2022, the VirtuaReal bilibili and Twitter accounts teased the upcoming Livers with an image of their silhouettes.

On 3 January 2022, VirtuaReal officially announced their sixteenth generation of Virtual Livers, including Karisa, accompanied by a teaser of their designs and profiles. Karisa made her first dynamic post and released her first video, a cover of the VOCALOID song "ヴィラン / flower" on the same day.

On 7 January 2022, VirtuaReal released an announcement trailer for the new VirtuaReal members.

On 12 January 2022, the sixteenth wave made their debuts in a stream relay on bilibili lasting from 19:00 to 23:00 CST, Karisa being the second.

• Sixteenth generation aka 167 - Karisa, Kiyuu, Girimi, and Sybil. They debut together.
• Karisa and Azusa - Karisa cited Azusa as her favorite senpai when she debut. Thought so far they haven't done any collab.
• Karisa and Nox - They became good friend. Nox recommended Hollow Knights and Valorant to Karisa.
• Karisa and Eine - They sang the 爱你 by Cindy Wong together on Bilibili's Ice & Fire Song Contest.
• Karisa and Awu - Karisa is Awu's vocal mentor and suggested some games for her to stream. Awu was the first liver who Karisa made an attempt to make friend with since her hiatus.

Karisa's fans are called 砂惑星 (Sand Planet). Karisa came up with this name in December 2022 after she returned from a long hiatus. Before the change it was 小砂糖 (Little Sugar).

• Karisa has two cats. One is named 储备粮 (Reserve food). Once after stream, she forgot to turn off the mic and was caught playing with 储备粮. The clip got over 10k views. The younger cat is named 一般般 (Ordinary). * Karisa said she didn't have too much input in her nurse outfit, causing the artist to give her big breasts. * Karisa likes big breasts but prefers if it is on somebody else's body. * Karisa made some fan art rules ** no AI training for controversial topics ** no depiction of Karisa as the uke / submissive side of a relationship

If you asked Karisa just what kind of person she is, she might answer by saying she is a strange person codenamed “KRS”, or perhaps currently cosplaying a young female character who is niche and has a long bird tail. And every time she particularly emphasises, if in the vicinity there appeared an eyewitness about a gigantic bird or perhaps an urban legend, she definitely does not know about it at all; what’s more she does not have any relation whatsoever to the black divine bird from Chinese myth. But the expression in her eyes when she denies it makes it very difficult for people to believe she isn’t hiding something.
