Remille is an adventurer who has lived through multiple loops. He was born into a lesser noble house and had always been a low-level adventurer, but after his recent death revealed his friends' treachery, he decides to take a different path. This time, he meets Princess Ciel, who claims that she can see Remille's true potential through her powerful Eye of Appraisal. With her guidance, Remille wonders if he can truly become a great sage or a rider of dragons. He also questions whether the catlike familiar he has tamed in past lives is actually a mighty behemoth, the strongest of magical beasts. Lastly, Remille hopes that this time, he will finally escape the deadly destiny that has claimed his life seven times already.
