LIL LEAGUE at BOOK ACT Z Oct 29-30

LIL LEAGUE said on September 8 that it will appear at BOOK ACT Z 2026 in Tokyo on October 29 and 30, adding to the lineup for an LDH-backed stage event that runs across five days in late October. The group’s social post promoted appearances on both dates and told fans to check the event schedule for details. Official event pages show BOOK ACT Z 2026 at THEATER MILANO-Za and list cast lineups by performance rather than a single full-group appearance. ### Which dates actually involve LIL LEAGUE members? BOOK ACT Z 2026 is scheduled for October 27-31, according to LIL LEAGUE’s official site and the ticketbook event page. The two productions are “Geinin Kokan Nikki” on October 27-28 and “Mou Ichido Kimi to Oritai” on October 29-31. October 29 and 30 are the dates tied to the LIL LEAGUE post. The official cast listings show LIL LEAGUE members spread across specific performances on those days, rather than a single joint stage slot for the full group. (lilleague.jp) On October 29 at 2 p.m., the listed cast includes Mahiro Okao and Hayama Momoda. On October 29 at 7 p.m., the listed cast includes Sena Iwaki, Tatsuhiro Nakamura and Akihiro Yamada, alongside Okao, Momoda and others. On October 30 at 2 p.m., Ren Watanabe appears in the listed cast. ### Is this a concert, a panel, or a stage play? LDH’s event description identifies BOOK ACT Z 2026 as a staged reading and theater-style event built around two works. The company said all performers are LDH artists and described the project as part of “LDH PERFECT YEAR,” with THE RAMPAGE’s Jin credited for planning and direction. The October 29-31 work is “Mou Ichido Kimi to Oritai,” which the official description says depicts friendship and youth among people chasing their dreams. (lilleague.jp) The October 27-28 work is “Geinin Kokan Nikki.” The available official materials do not show separate fan-signing times or panel sessions attached to LIL LEAGUE’s appearances. ### Where is the event and how much are tickets? (lilleague.jp) THEATER MILANO-Za is the listed venue for BOOK ACT Z 2026, according to the official LIL LEAGUE news post and the LDH announcement. Ticketbook lists reserved seats at 8,250 yen, including tax, and says resale service is available. Ticketbook also says entry uses TapTicket and that performance availability can vary depending on demand and earlier presales. (lilleague.jp) The page notes that cast members and show content may change. ### Why did the social post tell fans to check the schedule? The September 8 social post did not provide performance times in the text summarized in the briefing, and the official event structure helps explain that. (lilleague.jp) BOOK ACT Z 2026 is organized by date, title and cast, with separate afternoon and evening performances on most days. That means a fan looking for a specific LIL LEAGUE member needs the detailed program page, not just the date range. The official listings also show that not every LIL LEAGUE member appears on both dates. The October 29 evening cast differs from the October 30 afternoon and evening casts, making the schedule page the main source for who appears when. ### What should fans watch next? October 29 and 30 are the next key dates for LIL LEAGUE fans following this announcement. Ticketbook’s BOOK ACT Z 2026 page carries the performance list, cast breakdowns and sales information, while LIL LEAGUE’s official site and LDH’s event page carry the broader event notice and production details.
