Mine Yoshizaki is a Japanese manga artist and character designer born on December 2, 1971, in Isahaya, Nagasaki. He began his creative career by drawing dōjinshi, or self-published works, based on popular video games while a graduate student at Nagasaki University. Yoshizaki has cited this experience as foundational to his development as an artist, as it required him to learn all aspects of manga production from drawing to dealing with printers and editors. He later worked as an assistant to the manga artist Katsu Aki, and his first professional publication appeared in a compilation book released by Shogakukan in 1989.

Yoshizaki is best known as the creator of the long-running manga series Sgt. Frog, known in Japan as Keroro Gunsō. The series, which follows a platoon of frog-like alien invaders, began serialization in the magazine Shōnen Ace in 1999 and has continued for decades. It was adapted into an anime television series produced by Sunrise, the studio behind the Gundam franchise. In 2005, Sgt. Frog received the 50th Shogakukan Manga Award in the children's category. The anime has numerous films and specials, including Keroro Gunsō: KeroZero Shuppatsu da yo! Zen'in Shūgō! and Keroro Gunsō: Mushakero Ohirōme Sengoku Ranstar Dai Battle, all based on his original manga.

Prior to Sgt. Frog, Yoshizaki created the manga Arcade Gamer Fubuki, which was serialized from 1998 to 2002. This work was later adapted into a four-episode original video animation (OVA) series by the studio Shaft. Yoshizaki took a more direct role in the anime adaptation of his work, as he both wrote and directed a special six-minute OVA related to the series. The story follows a middle school girl with extraordinary video game abilities granted by a pair of magical underwear, reflecting Yoshizaki's deep interest in and knowledge of arcade gaming culture.

Beyond his original manga, Yoshizaki has had a significant career as a character designer and concept artist across multiple media. He provided the original character designs for the anime series Seven of Seven. He also served as the concept designer for the multimedia franchise Kemono Friends, which includes an anime series. In the video game industry, he has worked on character designs for several titles, including Pop'n Tanks! for the PlayStation, the Gradius spin-off shooter Otomedius, and the fighting game Soulcalibur IV, for which he designed the playable character Angol Fear. He has also collaborated with the Gundam franchise, designing mascot characters for the Gundam Card Builder game.

Yoshizaki's artistic identity is closely tied to his encyclopedic knowledge of video games, anime, and mecha, particularly the original Mobile Suit Gundam. His work in Sgt. Frog is renowned for its dense layering of parodies and homages to these properties, a quality that directly led to the anime being produced by Sunrise and sponsored by Bandai. This deep integration of otaku culture references, combined with a distinctively cute and rounded character design style, defines his creative output. His influence is significant in both the manga and anime industries, having created one of the most successful and long-running comedy manga of the 2000s while also shaping the visual identity of major game and anime franchises.
