Despite having helped them many times in his life, without knowing the reason, a legendary dragon is mortally wounded by a group of humans.
Then he wakes up in another world, precisely as a human, and although he maintains his memory and some powers, he decides to learn and live like them.
Years later, following the traditions in town, he begins to live on his own, but despite this, he maintains a close relationship with his family.
He has learned to use human magic and understands that his abilities can cause commotion, and he usually controls himself.
One day, he offers his help to research the disappearance of a race of lizards, who for some reason have abandoned their establishment, quite close to town.
While carrying out his investigation, he discovers that the environment has changed, and he believes that for that reason they can no longer find the lizards.
But that does not mean that he is alone, and he senses someone’s presence. Dolan, as his human parents named him, becomes alert, ready to defend himself.
At that moment, Celina appears, a half-woman, half-snake lamia, but although they are usually somewhat aggressive, Dolan observes that she does not seem to be.
Before they can talk, a huge monster appears in front of them and they decide to hide. Dolan asks Celina to use her powers to help him defeat the creature.
With a good strategy, and thanks to his dragon powers, Dolan deals the final blow.
Before returning to the village, Dolan learns more about Celina, who has left her home in search of a husband, who must be able to withstand her venom.
And although Celina seems to insinuate something to Dolan, he simply wishes her luck.
