TRILLIONSTAGE

On 5 August, TRILLIONSTAGE was launched. On 29 August, Sakiccho Mikuru made her debut. On 30 August, Heart no Myu made her debut. On 31 August, Sukoboshi Rei made her debut.

On 17 February, TRILLIONSTAGE announced Nanamine Nina and Sirase Suina's transfer from the indie group Date+Links! to the agency as their Generation 1.5. On 20 February, Nanamine Nina held her re-debut stream. On 21 February, Sirase Suina held her re-debut stream. On 18 November, ViV Silvey, Nyahoroba Tobari and Abyss Song Syndrome held their debuts as TRILLIONSTAGE's Generation 2. They are in a unit called "Jinrui Metsubou Bu" (人類滅亡部, lit. Humanity Extinction Club).

On 13 February, TRILLIONSTAGE announced the first 24-hour relay event stream for Gen 2 unit Jinrui Metsubou Bu, scheduled for 23 February.

From 25 to 26 January, Gen 1.5 members Nanamine Nina and Sirase Suina debuted their fully redesigned 2D models together in a 24-hour collaboration re-debut event, spanning 3 streams on their new Gen 1.5 unit channel, "DennoNEETRyodan" (電脳無職旅団, Cyber NEET Brigade). On 14 February, Horobi Madnight Oil, Shichitenbattouin Aegis and Utsutsu held their debuts as TRILLIONSTAGE's Generation 3 called "Daraku Gakuin" (堕落学院, lit. Depravity Academy). On 21 February, TRILLIONSTAGE announced an audition for a 4th Generation member. The humorous, creatively phrased announcement was followed by a (now-deleted) link that showed a "White Phoenix" (ホワイトフェニックス) VTuber model. On 12 March, TRILLIONSTAGE announced that Gen 3 member Utsutsu's channel got banned and deleted by YouTube, due to "ear nibbling" audio from her ASMR stream on 10 March. Her channel had previously received a warning plus a 1 week ban from YouTube on 24 February, in relation to a Daraku Gakuin "school song" video. On 14 March, Utsutsu re-debuted on her new channel. On the same day, she also did an apology stream as a response to the banning of her previous channel, promising to behave in a more prim-and-proper manner from that point on. On 1 June, TRILLIONSTAGE announced that Gen 1 members Sakiccho Mikuru and Heart no Myu have started a collaboration channel called "AiNatsu Studio" (あいなつスタジオ) where they will produce a series of voiced "youth manga" Shorts twice a week. On 4 July, Reone Crazy Jelly started her activities on YouTube with a pre-debut "collection" video. On 6 July, Pipipi Pino started her activities on YouTube with a pre-debut "confession" video. On 15 July, Shichitenbattouin Aegis's YouTube channel was banned and deleted by YouTube, apparently to "protect the Community". She had 130,000 subscribers at that point. Aegis stated that she was retiring (from YouTube, not from VTubing) after that, and moved her activities to Twitch. On 6 August, TRILLIONSTAGE announced that Sakiccho Mikuru was going on a 2-week medical hiatus. On 9 August, Aegis announced her debut on her Kick account. On 1 September, TRILLIONSTAGE Gen 1 (Sakiccho Mikuru, Heart no Myu and Sukoboshi Rei) celebrated their 3rd anniversary on the main TRILLIONSTAGE channel. On the same day, they also premiered their group cover of "POP IN 2" by B-Komachi on the same channel. On 7 September, Aegis announced that she was going on a streaming hiatus for mental health reasons. She clarified at the start of her tweet that she was not retiring, and that she will continue to be active on Twitter and FANBOX while she prepares for a renewal of her activities. On 2 October, Xiren Satellite started her activities on YouTube with a pre-debut stream playing Parasocial on her secondary English YouTube account. On 12 October, Aegis announced her return stream on Twitch, a singing stream scheduled later that day. On 21 October, TRILLIONSTAGE announced an audition for an ASMRtist idol VTuber. The announcement includes a teaser visual of a voluptuous, brown and blue-haired VTuber model, a tagline of "Turn your trauma into the ultimate magic" (トラウマを、最高の魔法に──, Trauma o, Saikou no Mahou ni-), and two very specific requirements: 1) a "painful past" and 2) a "desire to heal somebody." On 8 November, TRILLIONSTAGE unveiled its upcoming Generation 4 consisting of three members: Pipipi Pino, Reone Crazy Jelly, and Xiren Satellite. On the same day, Xiren Satellite started her main channel activities on YouTube with a pre-debut "apology" video. Her Japanese debut stream will be scheduled upon reaching 10,000 subscribers. On 14 November, Aegis released a statement announcing her intention to start over as a new "Shichitenbattouin Aegis" after losing her debut channel in July. On 21 November, Shichitenbattouin Aegis re-debuted on her new channel.

On 24 January, Pipipi Pino, Reone Crazy Jelly and Xiren Satellite held their debuts as TRILLIONSTAGE's Generation 4 called "Bakugekikai" (白撃会, lit. White Strike Society).
