Yoshihiro Kuroiwa (aka 黒岩よしひろ or Kuroiwa Yoshihiro), born in 1962 in Nagano, the capital of the Nagano Prefecture in Japan, is a Japanese family man, who has a wife and children. He works as a mangaka.

Yoshihiro Kuroiwa has the bloodtype 0 and has always done his best to follow the footsteps of the famous mangaka Yuuki Rin, both of whom have chosen Ecchi as the main genre for the representation of their works.

His other works are settled in the genre of mystery, dictionaries featuring photographs and other special types of subjects. Most of these works have been released via the publisher Shueisha.

His most well known masterpiece and all-time favorite of his fanbase, though, has been the series 鬼神童子 ZENKI (Kishin Douji Zenki), an original work by his colleague Kikuhide Tani.

His role in the KDZ Team

Yoshihiro Kuroiwa is the artist, who created all the artwork seen in the Manga, the anime, the games and the OVA of the Kishin Douji Zenki series.

The only exceptions of this are some of the author comment section drawings depicting his colleague Kikuhide Tani and the photographs of the original Kishin Douji Zenki team, which were photographed by a currently unknown photographer.

His cultural influence

Yoshihiro Kuroiwa once had the great honor to become an assistant to the famous mangaka Katsura Masakazu, during the latter's work on a short story called ビューティビースト (Beauty Beast) in 1983. This short story marked Shueisha's entry in 1983's 26th Tezuka convention alongside the partial short story 舞子ミステリアス (Maiko Mysterious) for the Fresh Jump Awards following Shueisha's flagship journal "Weekly Shonen Jump"'s official departure.

Outside from Katsura Masakazu's influence on his works, Yoshihiro Kuroiwa also wrote a book about self defense, that received a honorable poster, which was featured in Kenya and Australia, but was overshadowed by a well received work, which came out at rougly the same time.

This work was his series "Kishin Douji Zenki", which he had been working on alongside his colleague Kikuhide Tani and which had then been released from 1992 to 1996 via the "Weekly Shonen Jump".

Other than that, the series has also been released as the only major work by the Tokyo Television Network Co., Ltd. (aka "TV Tokyo") in 1995 as an anime series of the same name.

After Shonen Jump's separation from Shueisha in 2000, Yoshihiro Kuroiwa continued to create manga and anime for both young and adult readers and viewers, most of which are classics by now.
