Career
Yoshizaki also worked as an assistant to manga artist Katsu Aki. His first publication was featured in a compilation book published by Shogakukan in 1989. Yoshizaki, a graduate student of Nagasaki University, started from drawing his own doujinshi, based on video games that were famous at that time (somewhere in the 1980s).
With that doujinshi, he practiced and improved his drawing skills day by day.
Yoshizaki said that his experience in drawing doujinshi was the most priceless experience that he ever had. According to him, making doujinshi gave him the opportunity to seek through the world of the manga industry, with all aspects from drawing to producing (meeting with printers, editing process etc).
This allows him to do all the work, rather working in a big-scale production company that lets him work in one particular branch. He is best known for his manga Keroro Gunso, published as Sergeant
Frog in the United States, which was first published in the Japanese manga magazine Shōnen Ace.
He is also the creator of Arcade Gamer Fubuki and did character design on the series Seven of Seven. Works:
1993–1995: FANTASWEAT
1993–1995: Detana!! TwinBee (spin-off from the video game Twin Bee)
1994–1995: 8BIT FIGHTER SHIEN
1995–1997: Space Juubei
1997-1998: Yume no Crayon Oukoku
1996–1998: VS Knight Ramune & 40 Fire
1998–2002: Arcade Gamer Fubuki
1999–present: Sergeant Frog
2000–2003: Dragon Quest Monsters +
2007–2011: Otomedius (spin-off from the Gradius series)
Due to various Gundam references, an ongoing Sergeant
Frog anime was produced by Bandai.
This led to Yoshizaki collaborating on certain Gundam projects, such as designing the mascot girls Reiko Holinger and Catharine Blitzen for the Gundam Card Builder game. He has also been the designer of the Angel-XX figurine series from Neon Genesis Evangelion.
His latest work was for Konami"s new Gradius-type shooter Otomedius, which he did the character designs foreign This is significant because, instead of simply moving a fighter craft around, the player controls a unique character bound within a vehicle.
He has also designed a playable character called Angol Fear (a nod to his character Angol Mois in Sgt Frog – they even wield similar weapons) to the fighting game Soulcalibur IV.
