The First-press Limited Edition A includes a Blu-ray with the bonus video “Seitokai, Let Us Handle It! ~Let’s Go on a Field Trip~” and a replica canvas-style card. The First-press Limited Edition B comes with a bonus CD of remastered previously unreleased songs and a “Shichijigen Seitokai, Activities Begin!” replica profile sheet in a deluxe package.

Retailer-Exclusive Bonuses and Pre-Order Information

The Nijisanji Official Store offers an acrylic stand (paid bonus) and a replica handwritten comment card (free bonus), plus an early pre-order bonus of an another jacket photo card for orders placed by September 9. Amazon offers a mega jacket, Animate offers a set of 6 aurora stickers, and Gamers offers square tin badges, with different bonuses available at each retailer.

Pre-orders opened on August 19, 2026 at 21:00 at CD retailers nationwide. All first-press editions across the three formats include a serial code for the musical live ticket priority lottery.

Musical Live at Pia Arena MM

On January 23, 2027 (Saturday), the “Shichijigen Seitokai! The Movie ~Together Forever Grand Operation!~” musical live will be held at Yokohama’s large-scale venue Pia Arena MM (approximately 10,000 capacity). Doors open at 17:00 with the show starting at 18:00. Live viewing options are also being considered, with details to be announced on Nijisanji’s official X.

Release Events Confirmed

To celebrate the soundtrack release, talk-style release events will be held in Tokyo on February 13, 2027 (Saturday). Part 1 (from 13:00) targets Tower Records purchasers, while Part 2 (from 16:00) targets Animate purchasers, both operating on a lottery invitation system.

Future Developments

Shichijigen Seitokai! consists of six members — Kanae, Higuchi Kaede, Saegusa Akina, Ryushen, Leos Vincent, and Suo Sango — who stream content every Wednesday. The media mix strategy expanding from the theatrical movie to a soundtrack and then to a 10,000-capacity musical live demonstrates the unit’s growth as a VTuber IP. Details on the ticket priority lottery and additional information will be updated on the special website.

Commentary and Outlook

A VTuber unit releasing a theatrical movie soundtrack and then holding a musical live at a major 10,000-capacity venue like Pia Arena MM represents a significant milestone in the maturation of VTuber content as intellectual property. Shichijigen Seitokai! has entered a new phase with this cross-media expansion spanning video, music, and live performance.
