Mizuki Tsujimura's 'Fire Dome' Released on June 5 with Author Message & Campaign

Shogakukan has published 'Fire Dome' (Upper and Lower volumes) by Naoki Prize-winning author Mizuki Tsujimura on June 5, 2026, marking her 22nd debut anniversary. The massive 1,500-page mystery novel, based on 25 serialized chapters in 'STORY BOX' (June 2019 to August 2023), underwent major revisions for this release. The story centers around the public frenzy and 'rumors' surrounding a department store receptionist's kidnapping and murder 25 years ago in a regional city. To celebrate, Shogakukan launched a special website featuring author messages, reader reviews, and a 30-page preview. Bookstores nationwide offer a special 'clear sleeve' bonus for customers purchasing both volumes together. An X repost campaign runs from June 5 to June 18, 2026, offering 22 winners a 1,000 yen book card. The novel is published in B6 hardback format, with the upper volume containing 464 pages and the lower volume 432 pages. Each volume is priced at 2,090 yen (tax included).
