Segawa published the supernatural action manga The Enchained Spiritual Beast Ga-Rei from 2006 to 2010 and Kadokawa published the series in 12 compiled volumes.
In addition, Takeru Kirishima is also drawing a manga adaptation of Yuiko Agarizaki’s Ryūgoroshi no Brunhilde (Brunhilde the Dragonslayer) novel.
He launched the “afterschool psychic action” series in Kadokawa’s Monthly Shōnen Ace magazine in 2010, shortly after ending Ga-Rei.
He also drew the illustrations for Usagi Nakamura’s Gokudo-kun Manyuki (Gokudo) light novel series, which inspired a 1999 anime.
