Hiroshi Shiibashi was born in Suita, Osaka, on June 6, 1980. He graduated from the Osaka University's Faculty of Arts in the Department of Imaging. He begins his career in manga as an assistant for Hirohiko Araki. During this period, he becomes friend with Yasuki Tanaka.

In 2002, Shiibashi publishes his first one-shot "Aramata" in Business Jump. He publishes several other one-shots from 2002 to 2008 for Shueisha, but also the Osaka University of Arts. His first serialized work is Nura: Rise of the Yokai Clan, published on Weekly Shonen Jump from 2008 to 2012.
In 2014, his new series ILLEGAL RARE is published in "Weekly Shonen Jump".
