Ryuji Yoshizaki

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.

FUN FACTS

Tower of God and The 8th Son? Are You Kidding Me? both premiered on 2 April 2020. He wrote nine episodes of the first, a webtoon adaptation made by Telecom Animation Film, and two episodes of the second.

Girl Gun Lady began on 5 April 2021 as a live action series for MBS and TBS. It centres on a high school student and a model gun, and he is credited on three episodes.

Grand Guignol reached cinemas on 28 October 2022, and The Quiet Don: Chapter 1 on 12 May 2023. He wrote the screenplay for both films.

GARO: Heir To Steel Armor began on 11 January 2024. It belongs to the long running tokusatsu franchise, and he wrote five of its episodes.

Love Me to Death is an eight episode crime drama made for ABEMA, first shown on 27 March 2025. He wrote the screenplay.

Queen-B is the writing group he belongs to, and Hold on, Harutora-kun is the series on which he works alongside Mikiko Takahashi. Tower of God is the largest single block of episodes on his list, with nine of them carrying his name.

In my view his list is unusual for how different the commissions are: a webtoon adaptation for anime, a tokusatsu franchise, a crime drama for ABEMA and now a boys’ dormitory romance. What stays with me is that a writer with so many genres behind him gets Hold on, Harutora-kun as his first boys’ love series and shares the writing with a second writer. I would start with Girl Gun Lady, since it is another MBS commission, and then watch Harutora-kun.

TRIVIA

Two of his credits are for MBS, five years apart: Girl Gun Lady in 2021 and Hold on, Harutora-kun in 2026.

Hold on, Harutora-kun is his first boys’ love series.

Both of his feature screenplays reached cinemas on a Friday, Grand Guignol on 28 October 2022 and The Quiet Don: Chapter 1 on 12 May 2023, about six and a half months apart.

Across the six series on his list he is credited on thirty five episodes in total: nine of Tower of God, two of The 8th Son? Are You Kidding Me?, three of Girl Gun Lady, five of GARO: Heir To Steel Armor and eight each of Love Me to Death and Hold on, Harutora-kun.

About fourteen months lie between the start of GARO: Heir To Steel Armor in January 2024 and the start of Love Me to Death in March 2025.

From the first premiere on 2 April 2020 to Hold on, Harutora-kun on 13 August 2026 is a span of six years and four months.
