Background
His activity started simultaneously on 2 June 2018; his Twitter account and YouTube channel was created and his introduction on YouTube was uploaded on the same day, curiously right after Kaiji's account termination. Several VTubers welcomed him back on the comment section of his introduction
Relationships
- "Chinroutou" (朕狼党), along with Memento Vanitas, Mochizuki Hoguno, Dasoku, Nigongo, Yagami Tsukumo, Togami Jin, SHAKA, Tachibana, Seed, Daiquiri, Sorahoshi Paru, and Kenki. This group was formed in October 2025 during the MADTOWN GTA event.
Trivia
- When Tsukasa was a part of NIJISANJI NetWORK, he played Project Winter with several NIJISANJI members and Fairys; Tsukasa hid the screen to make the room private, but he forgot to unhide the screen and all the viewers could seen was his stream background (tatami) until Ange Katrina pointed out, thus the term "tatami" was coined for a VTuber forgetting to unhide the game screen.
- Despite parting ways with NIJISANJI in 2019, he can often still be seen on the NIJISANJI official YouTube channel hosting special events and making appearances in video segments such as PUCHISANJI and NIJISANJI Koshien.
- Tenkai appears in "Ruriiro Days -Heavenly Blue-", a visual novel game starring Asano Ruri, Asano Akane, Annin Miru, and Amenosei.

More Info
2019
On 23 March, he volunteered to help Kashiko Mari during her 3rd live event, MARism Vol.3 at WOMB in Shibuya, Tokyo along with Saionji Mary, and Yu T Kyu.
On 10 May, it was announced that he will be one of the first two participants (the other being Fairys-chan) of NIJISANJI's NIJISANJI NetWORK program, a partnership program that is meant to support virtual talents.
On 31 December, the NIJISANJI NetWORK program was ultimately terminated, with Tsukasa and Fairys returning to independent VTuber status.
