The Summoner Who Doesn't Belong to This Era

[Beast Taming] An online food delivery rider who died after jumping from a building transmigrates to a world of beast tamers. He transmigrates into the body of a useless summoner, but his soul possesses all five elements, making him a five-color summoner. Four-color and five-color summoners are both legendary talents, and no five-color summoner has appeared for thousands of years. Beneath the useless exterior lies a genius of legendary caliber. Branded a failure, he accomplishes what even geniuses cannot.
