GAMABOOKS, an online bookstore operated by PLAN-B LLC, and Gakken will hold the first collaborative streaming event between the Gakken Picture Book LIVE series and academic VTubers. The event consists of four YouTube live streams scheduled for August 2026, during the summer vacation period. Each stream will feature Gakken Picture Book LIVE editor-in-chief Matsubara Yoshiyuki as a guest, alongside a different academic VTuber specializing in the theme of that session. The host will be GAMABOOKS bookstore clerk and VTuber Moroboshi Meguru, who is known for folklore and modernology content and hosts the academic VTuber relay stream School of Tube. The sessions cover the Space, Dinosaurs, Human Body, and Rocks, Minerals, and Fossils editions of the picture book series. The streams aim to present picture books as something to discuss and enjoy together, rather than just read, combining VTuber-friendly talk with specialized knowledge for both children and adults. The first stream is scheduled for August 13, 2026, at 20:00 JST on Moroboshi Meguru's YouTube channel.
The four streams pair each picture book theme with a VTuber whose expertise matches the subject. Usui Kuria, a rocket idol VTuber specializing in aerospace engineering, will handle the Space edition on August 13. Haku Mauru, a paleontology VTuber known for her Geologic Time Memorization Song, takes the Dinosaurs edition on August 17. Dr. Shironoko, an active internal medicine doctor VTuber, covers the Human Body edition on August 19. Gomomo, a gemstone polishing apprentice VTuber, handles the Rocks, Minerals, and Fossils edition on August 27.
Matsubara Yoshiyuki, editor-in-chief of Gakken Picture Book LIVE since 2023, will share behind-the-scenes stories about creating the books. He holds a Ph.D. in biological sciences from Nagoya University and previously worked on the Dinosaurs New Edition and the Dragon Drill series. The streams will be hosted on Moroboshi Meguru's YouTube channel, with each session running from 20:00 to 21:30 JST.
GAMABOOKS, which operates under the concept of making encounters with books more interesting, has positioned this event as a way to introduce picture books to people who rarely encounter them, while offering children a familiar entry point during summer vacation.
