BIOGRAPHY
Ryuji Yoshizaki (Japanese: 吉﨑崇二, Yoshizaki Ryūji; born 1979 in Saitama Prefecture) is a Japanese screenwriter and a member of the writing group Queen-B. He works across anime, tokusatsu, live-action drama and film, and in 2026 he co-writes MBS’s boys’ love series Hold on, Harutora-kun.
His filmography opens in 2020 with two anime commissions in the same month. He wrote nine episodes of Tower of God (神之塔), the adaptation of the Korean webtoon produced by Telecom Animation Film with Naver Webtoon and Crunchyroll, and two episodes of The 8th Son? Are You Kidding Me?. In 2021 came Girl Gun Lady (ガールガンレディ) for MBS and TBS, a live-action series built around a high school student and a model gun. Two feature screenplays follow, Grand Guignol (2022) and The Quiet Don: Chapter 1 (2023). In 2024 he wrote five episodes of GARO: Heir To Steel Armor (牙狼<GARO> ハガネを継ぐ者), an entry in the long-running tokusatsu franchise, and in 2025 he took the screenplay on Love Me to Death (死ぬほど愛して), an eight episode ABEMA crime drama.
Hold on, Harutora-kun (ちょっと待とうよ、春虎くん) began on MBS on 13 August 2026 across eight episodes. It is adapted from a manga by あめきり, directed by Keisuke Shibata and Kishida Masayoshi, and written by Ryuji Yoshizaki with Mikiko Takahashi. The premise puts a guarded student called Sui into a boys’ dormitory, where he survives by staying indifferent until a warm and disarmingly honest new roommate starts pulling the walls down. Tsubasa Nakagawa plays Sui Kishida and Masaya Sakuragi plays Harutora Kurobe.
Ryuji Yoshizaki has written for anime, tokusatsu, crime drama and film across eight credited works since 2020.
His first two credits, Tower of God and The 8th Son? Are You Kidding Me?, both premiered on 2 April 2020. Girl Gun Lady in 2021 and Hold on, Harutora-kun in 2026 were both made for MBS, five years apart.
Two of the eight works adapt existing comics: Tower of God comes from a Korean webtoon, and Hold on, Harutora-kun from a manga by あめきり, which has its own page as Hold on, Harutora-kun (Manga).
The credit types differ. He is credited for nine episodes of Tower of God and five of GARO: Heir To Steel Armor, takes the screenplay credit on Love Me to Death, and shares the writing of Hold on, Harutora-kun with Mikiko Takahashi.
