Rina Kawaguchi is an active voice actress with three announced roles across 2026 and 2027 projects: Eliza in the Seven Sleeping Beauties TV anime, Shozen in the Shozen anime, and an unnamed character in the From Overshadowed to Overpowered anime.
Rina Kawaguchi appears in three anime projects announced between July and August 2026. Her first confirmed role is Eliza, one of the seven sleeping princesses in the Seven Sleeping Beauties television anime, which is scheduled for a 2027 debut. The adaptation is produced by Studio Gokumi and AXsiZ SMASH, with Mankyu directing. Kawaguchi is part of a seven-actress cast that also includes Aya Yamane, Yoshino Aoyama, Miku Ito, Ayasa Ito, Kana Ichinose, and Fuka Izumi.
In August 2026, Kawaguchi was announced as the lead voice of Shozen in the television anime adaptation of the Chinese manhua Shang Shan. The series, titled Shozen, premieres in April 2027 and airs in the B8station programming block on Fuji TV. She voices the title character, a young girl raised by supernatural creatures, opposite Hiroshi Kamiya as Dozen. The same week, she joined the cast of the From Overshadowed to Overpowered anime, playing a character appearing in the seventh episode, alongside Shinichiro Kamio and Hiroki Takahashi.
The three roles span different genres and production teams, from a fantasy romantic comedy to a manhua adaptation to an ongoing series. Kawaguchi's casting in Shozen as the lead marks a prominent position, while her role in Seven Sleeping Beauties places her within a large ensemble. The From Overshadowed to Overpowered role is the least detailed, with no character name or episode-specific information beyond the seventh episode appearance.
