Sana Tsukomo (九十九 佐命) (born June 10, 13.8 billion years ago, according to lore) is an Australian VTuber who is associated with Hololive EN's second generation, HoloCouncil. She debuted with four other VTubers, Fauna Ceres, Kronii Ouro, Mumei Nanashi and Baelz Hakos.


On the 23rd of August, Sana released her debut video, where she talked about herself and her interests. Prior to this, she had uploaded a short. She revealed that she liked pasta, macarons, and round things like baby seals and planet Earth, and when asked for her dislikes, she stated that she disliked sneezing, as her sneezes could potentially destroy the Earth, and that she thought that mosquitos were a mistake. She also discussed her hobbies, astronomy, astrology, graphic design, drawing, traveling, hiking, snorkling, camping, and eating.

Sana also stated that her favorite games were "cute, bad, and psychological" games and that she also enjoyed Pokémon. Like most of Hololive-EN, she was also an anime fan, with her favorites being Kyousouguga, Uchouten Kazoku, and Katanagatari. She also talked about music she liked, which included electronic dance music (including Moe Shop and Ujico*/Snail's House), Go Shina, YOASOBI, and Eve. She also stated that her dreams were to get a telescope, try astrophotography, see her mascot Yatagarasu in 3D, collect the laughter and smiles from everyone, and last a year (i.e. until 23 August 2022) without destroying the Earth.

Sana has stated that regarding her schedule and content, she plans to make astrology streams (performing astrology with the hashtag #Holoscope) and "Kuso Monday", a series where she plays rubbish games.

The next day, she uploaded the first episode of her weekly series Holoscope, titled "【#Holoscopes】01. What bread are you?". The series was about astronomy, star signs and what they indicated about the viewer. She also streamed the games Celeste and Rhythym Heaven Fever, and on the 27th of August, she hosted a watchalong of Insterstellar (2014) along with Kronii. On the 9th of September, she uploaded her first drawing stream.[1]

Other games she has streamed include Fight Crab, SOMA, I am Bread, Celeste, Beat the Beat, Warioware:Get It Together, The Artful Escape and Minecraft.


A member of the Council and the Speaker of "Space," the very first concept created by the Gods.

After being materialized in the mortal realm, she began researching astrology in earnest for one particular reason. However, she soon stumbled unknowingly upon the Forbidden Truth, and was turned into an apostle for the Ancient Ones.

"Space" refers not only to this universe we live in, but all dimensions and matter to exist. It is a concept unbridled by definition, and one that continues to grow in scope limitlessly. As it is yet to be fully explored by man, her seemingly strange behavior and speech can be explained away with a simple, "Humanity simply isn't yet ready to understand."

As a side note, despite how she may look, she is quite chi... young.


  • She shares her ties to the ancient ones with Ina'nis Ninomae.
  • Sana is also 138 billion years old, and is larger than earth's sun (specifically, she is 1,697,840,000,000 cm), but shrinks herself when she visits earth. The antenna on her head is a limiter which prevents her height from increasing. If removed, her gravitational field would fling Earth out of orbit and wipe out the entire human race. She actually did destroy the earth once by removing it but luckily Fauna was able to restore it with her apple.
    • However, her official hololive profile lists her age as 13.8 billion years old.
  • Sana's mascot is Yatagarasu. Its true form causes human minds to melt upon viewing it, so it takes the appearance of a cute, three-legged crow tit. It occasionally vomits out wishes, and speaks bird language, though Sana is able to understand it.
  • She removed her limiter in her debut but somehow the viewers survived.


  • "Where does the difference lie between 0 and 1? The only way to save the void is to validate the existence of "Space".
  • "BIG HELLO! Sana has landed on earth!!!!!! Did you know that when you trip into a black hole you turn into spaghetti?"
