[2026 Edition] VTuber April Fool’s Day Jokes: Top Picks

April 1st is April Fool’s Day. Every year, VTubers routinely perform all sorts of pranks, but some go all out with elaborate preparations, such as creating dedicated websites and 3D models. This time, we’ll pick out and introduce some of them.

Ryushen Nijisanji and Toujirou Genzuki begin producing five idol units, but…

Nijisanji’s Ryushen and Toujirou Genzuki‘s unit “Harassment Kojirase” posted an important announcement video declaring the end of their idol activities. At the same time, they announced five new idol units consisting of Nijisanji’s VTubers, calling themselves a “All-Produced Humanity Creation Idol Unit.”

All five groups had their own unique visuals prepared, and even crossfades featuring songs written and composed by Toujirou Genzuki were prepared, showing such thoroughness that it made you think they were actually going to produce idols. However, around noon that day, all units except Harassment Kojirase announced their disbandment in an “important announcement.” They spared no effort and gave it their all for the sake of the joke.

Furthermore, Nijisanji’s official account has also posted a project called “Idol Sushi” as an idol-themed post. They have prepared a dedicated website and will be selling limited-edition merchandise starting April 1st.

Nijisanji’s Higuchi Kaede collaborates with manga artist Kumeta Koji.

Nijisanji’s Kaede Higuchi announced that Kumeta Koji, a popular manga artist known for works such as “Zetsubou Sayonara Sensei” and “Katte ni Kaizou,” will be posting a new manga series titled “Hibikimei Kanadero” with Kaede Higuchi as the main character.

Around noon on April 1st, it was announced that the series would be canceled due to Fool April’s Day, but it was later revealed that the collaboration with Kumeta Koji actually took place, and that the manga would be adapted into a music video for Higuchi Kaede’s original song “Kyoumei”. Kumeta Koji has a deep connection with Higuchi, having designed the main artwork for the additional Namba performance of her 2020 live tour and the kimono costumes for Tsukino Mito, so there is much anticipation for what this music video will be like.

Hololive’s Pekora Usada unveils new outfit for Mummy Pekora.

Hololive’s Pekora Usada has made it an annual Fool April’s Day prank. Every year, she spends a lot of time and effort working on her pranks for April 1st, and this time she announced that she would be revealing a new outfit for her mother, Mummy Pekora.

Mummy Pekora originally started as an Fool April’s Day project where Pekora’s real mother was turned into a VTuber. The response was tremendous, and despite being an ordinary person not affiliated with Hololive, she has gained a large number of enthusiastic fans. Pekora herself is surprisingly enthusiastic about it, and her enthusiasm for entertaining fans is so great that she sometimes gets scolded by Pekora. They are also accepting fan art predictions for her costume, so we are looking forward to seeing what she will look like this time.

Hololive’s AZki posts a silhouette of herself in a nostalgic look.

Hololive’s AZki has announced that she will be making her debut live stream on April 1st. Of course, this isn’t her first live stream, as AZki has been active as a VTuber for many years, but what’s intriguing is the silhouette that has been released. The image is reminiscent of AZki’s appearance in the early stages of her career.

AZki was previously affiliated with “INONAKA MUSIC,” an independent music label within Hololive, and during that time, she had a futuristic design as a music artist. After officially joining Hololive, she changed to a more innocent, idol-like appearance. This latest post will bring back nostalgic memories for long-time fans, but what will she actually look like?

Hololive’s Hakui Koyori joins VRChat with a fluffy avatar.

Hololive’s Hakui Koyori announced that she will be unveiling a 3D model of her mascot character “Mofukoyo,” and posted a short teaser video. Mofukoyo was originally a fan-made character based on an anime, and was previously posted with voice acting on Hakui Koyori’s official channel.

The announcement will be held in VRChat, a platform that has seen an increase in Hololive VTubers visiting in recent years. The EN members, in particular, actively use it, and have even posted their own original world, “holonatsu Paradise official world,” officially. Marine Houshou, who also unveiled Kumarin’s 3D model in VRChat, will be participating in this broadcast, so what kind of encounter will it be?

A VTuber debut from the smartphone game “Ensemble Stars!!”?

The popular smartphone game “Ensemble Stars!!” has announced that a new VTuber unit, “Queen Undersea Labyrinth,” will debut on April 1st. The three members making their debut are Kuin Karetsu, Mayou Meiro, and Umimi Ocean.

Although the press release states that it’s a limited-time campaign on April 1st, YouTube has announced the debut streams of three VTubers, and the early streamer, Kuin Karetsu, even has a fully-fledged Live2D model, indicating that it’s a full-fledged project. There are also listener names and fan art tags, which are common for VTuber debuts, faithfully recreating VTuber culture.

A romance adventure game from High Aogiri School?

High Aogiri School has announced “My Date Blind is a One Serious, So I Have No Out Way,” a romance adventure game featuring Tamako Otodama and Komaru Kurikoma as childhood friend heroines. The teaser site that was released had a spoiler waiting at the bottom for April 1st, but High Aogiri School doesn’t stop there. They have started taking pre-orders for some serious merchandise, rings that are designed to resemble wedding rings for the two girls.

ViviOn, the company that operates High Aogiri School, has acquired Aisis, the company that operates the download sales site “DLSite,” and the VTubers from High Aogiri School also sell ASMR audio and other content. Furthermore, there is a precedent of a game created by Urutora Girl being released, which has led to speculation that a game might actually be released in the future.

Sisters Omega post a bizarre ASMR video.

Rio Omega of the twin VTuber duo Sisters Omega posted an ASMR video, something she doesn’t usually do. The title is “[For ASMR Beginners] A Gentle and Healing ASMR,” but the actual video is quite bizarre.

From the very beginning of the video, Rei Omega and Sis Omega start off by picking at the ears of a mannequin’s head (made of styrofoam), then proceed to put the Rio Omega and Rei Omega headgear that they wear at events on the mannequin and have a field day. They make a surprise chicken sound, scatter bubbles everywhere, and blow air into it with inflated balloons, creating a series of surreal scenes. ASMR is a popular genre among VTubers, but Sis Omega always goes their own way even with this type of video. It seems they will continue to make interesting videos in the future.
