‘Case Closed’ Vol. 109 Debuts at No. 1 on Billboard Japan Book Hot 100

Gosho Aoyama’s Meitantei Conan (Detective Conan/Case Closed) Vol. 109 hits No. 1 on the Billboard Japan Book Hot 100 chart released Oct. 22.

Released Oct. 16, the volume debuts at No. 1, dominating brick-and-mortar and e-commerce (EC) while placing No. 14 in e-books. The volume reveals the untold pasts of Chihaya Hagiwara and Jinpei Matsuda, who played key roles in this spring’s animated movie Detective Conan: Fallen Angel of the Highway. Last week’s No. 1, Taiki Kawakami, Fuse and Mitz Vah’s Tensei Shitara Suraimu Datta Ken (That Time I Got Reincarnated as a Slime) Comic Edition Vol. 33, slips to No. 2 while topping e-books and hitting No. 2 for brick-and-mortar.

Yu Nagira’s Nanji, Hoshi no Gotoku climbs 4-3, leading both subscriptions and social media and placing No. 3 in brick-and-mortar, marking its 49th week on the chart. The film adaptation — starring Ryusei Yokohama and Suzu Hirose and directed by Michihito Fujii — opened Oct. 9, and the tracking period corresponds to its second week in theaters.

Released Oct. 16, the volume brings the representative match between Wolfgang and Schwarzer Wolf to its decisive bout, pitting Sunraku against Psyger-100 — two players who share the same goal of defeating Lycagon but have taken different paths to get there. The TV anime’s third season is set to air for two consecutive quarters starting Jan. 10, 2027.

Daisuke Ashihara’s World Trigger Vol. 30 slips 2-5, placing No. 5 in brick-and-mortar and No. 4 in e-books.

Nagira’s Hoshi wo Amu rises 18-7. The sequel to Nanji, Hoshi no Gotoku places No. 3 in social media, giving Nagira two titles in the top 10. Afro’s Yurucamp Vol. 19 lands at No. 8 (up from No. 10), with Hiromu Arakawa and Yoshiki Tanaka’s Arslan Senki Vol. 25 at No. 9 (down from No. 3). Rounding out the top 10 is the debut of Seimaru Amagi and Fumiya Sato’s Kindaichi Papa no Jikenbo Vol. 5, which places No. 9 in brick-and-mortar and No. 15 in EC.
