#Nijisanji Releases “Page of Lambda” Opening Animation Featuring “Sanbaka” Trio

What if Nijisanji VTubers Ange Katrina, Inui Toko, and Lize Helesta — collectively known as “Sanbaka” — had an anime that depicted them as adventuring companions in a fantasy world? That’s the premise for the Page of Lambda project, which includes a nicely-produced 90-second opening animation that is now up on the Nijisanji YouTube channel and features the tagline: “The more they know, the more they know they don’t know.”

Aside from the opening video, there will be a design works collection book that will go on sale on the Nijisanji online store (a fancier edition is also available), Amazon Japan, and Rakuten on August 19. Goods like can badges and visual towels are also part of the plan.

The Page of Lambda opening animation video is directed by animator Riki Matsuura (Undead Luck Opening 1 storyboard artist, director, and key animator), who also drew the character designs and contributed to the key animation. The animation production credit is held by ENISHIYA, the studio that produced Episode 14 of Frieren: Beyond Journey’s End and Episode 6 of Delicious in Dungeon.

Other staff credits include:

• Color designer: MAPPA’s Ayako Suenaga (Hell’s Paradise)
• Art director: Sagako Itakura (“Sore o Ai to Yobu Dake” music video)
• Compositing director: Yu Wakabayashi (Princess Principal)
• Sub-character designer: Hideyuki Morioka (Undead Unluck character designer)

The song that’s used in the opening animation is “Try add” by the Nornis unit, which currently comprises Chima Machita and Inui Toko.

According to their VTuber lore, Ange is an alchemist, Inui a cerberus who works at a Japanese-style tea shop, and Lize the second royal princess of the Helesta Kingdom.

The project’s website includes a fake Episode 1 preview. Its synopsis says that Lize is on a journey around the world as training and encounters her old friend Ange along the way.
