Quality Assurance in Another World Vol. 4 (Kodansha, 2021)

The once powerless NPC, Gaydle, was modified by Yamanaka, another King's Seeker and debugger like Haga. In return, Gaydle received an incredibly powerful body. Alas, the warriors of the mountains have had it with his barbarous ways and want him gone. It doesn't take long for Haga and his party to be dragged into their deadly battle...one of many remnants of debuggers gone amok in this imperfect world.
