From the weakest summoner to the world’s greatest dragon knight. The adventurer Jay was mocked by those around him as the “Lizard Summoner.” Although he was a professional summoner, the only summon beast he could call forth was a small lizard, which led him to be despised. As a result, Jay couldn’t form a party with anyone and continued his adventure alone, cherishing his little lizard, Kyuk. But one day, suddenly Kyuk grew into a huge and magnificent dragon – Bahamut! Seizing this opportunity, Jay began working as a carrier. Before long, rumors of the “Carrier Dragon Knight” spread throughout the royal capital, and everyone started to rely on him. From the mocked F-rank summoner to the world’s greatest dragon knight. A reverse unbeatable fantasy life kicks off.
