Reiji Kawashima's recent casting announcements span several genres and release windows. In May 2026, he was announced as Keel, a boy with a strong attachment to money, in the second season of Hell Mode, which premiered in July 2026 on Tokyo MX, MBS, and BS Nippon Television. The role placed him alongside veteran actors Hikaru Midorikawa and Miyu Tomita in a supporting cast expansion.
In June 2026, Kawashima was confirmed for two more projects. He joined the cast of The Fledgling Demon Lord's Starter Shop, a fantasy-comedy adaptation set for a January 2027 premiere, and he appeared in the cast reveal for Magic Repo Man, an October 2026 fantasy action series on TV Asahi. Both announcements came with promotional materials, but specific character details were not disclosed in the stories.
In July 2026, a voice PV for the BL manga Rainen no Koto o Ie, Ore ga Warau featured Kawashima alongside Ryota Iwasaki, marking the series' conclusion with its second volume. In August 2026, two more roles were confirmed: one of the seven knight brothers in Seven Knights of the Marronnier Kingdom, premiering October 3 on NHK Educational, and Mars de Colón, a member of Spain's national team, in The Prince of Tennis II: U-17 World Cup Finals Member Decisive Match, premiering September 30 on TV Tokyo. The stories do not indicate any overlap or conflict between these commitments.
