Tensai Saijaku Mamonotsukai wa Kikan shitai: Saikyou no Juusha to Hikihanasarete, Mishiranu Chi ni Tobasaremashita

Allow me to introduce myself, I am Phil Garden. Despite being told I had no talent, I used every resource at my disposal to become a decently-ranked "demon tamer." With the esteemed task of defeating the "Demon King" that I had earned, I found myself caught up in an incomprehensible phenomenon, torn apart from my demon–slave—that I had crafted into the strongest existence, and banished to a far-off land. Powerless, without connections or money, this is a story of how I lost everything to the Demon King’s plot, only to find new companions in a foreign land and strive to rise again as the strongest.
