The F-Rank Summoner Quits Adventuring to Become the Strongest Dragon Knight: The Summon He Raised as a Pet Grew up to Be a Bahamut!

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, Kucck... But one day, suddenly Kucck 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!
