Hiro Ashagi was a JSDF officer in charge of the special weapons group for the Fleet Intelligence Command department.
Ashagi and five other JSDF officers joined agent Christopher Kurtz after they discovered Samuel Yeager's residence. Shortly after Ashagi and his men infiltrated his house, Kurtz tripped a trap that set off a bomb, incinerating the building. Fortunately, Ashagi and the others got out before they were caught in the explosion. Ashagi and his officers later assisted Kurtz, as well as Jordan Aguilar and other NCIS officers during their raid on one of Edoga Kanashiro's warehouses. With their combined forces, Ashagi and the others managed to capture and arrest Kanashiro. (Trial by Fire)
