Good Bye, Dragon Life

A normal high school boy Kisaragi Ryuji's peaceful life is turned into an adventure by the return of his second cousin Eriko. Ryuji and Eriko seize a relic box from a black broker. In the box, they find a red dragon girl Rose. In order to protect Rose from the black organization, Ryuji decides to fight using his power as a relic handler.

Our hero needs to come out of his shell... literally! Reborn in another world inside a dragon egg, he doesn’t have the amazing magic or mighty physical strength of your typical isekai’d adventurer just yet. He’ll need to break free and grow from a weak hatchling and into a fearsome beast if he wants to escape the deep, dark forest unscathed. What battles and adventures await him in this unique take on the isekai phenomenon?

The story takes place in Dragon Country. Nonoko is a newly appointed dentist and her mission is to protect the dragon, the guardian of the country, from tooth-cavity bacteria. One day, amid increasingly fierce battles with the neighboring country, Nonoko finds on the dragon's tooth an unconscious boy soldier from the enemy country. His name is Bell, and he has been resurrected from inside the tooth by the dragon—a supernatural phenomenon that legend says occurs before a major disaster. As Nonoko and Bell go through a series of fierce battles, they eventually learn to accept their fate.

Dragons reign terror over the earth, sea and sky. If sworn dragon hunters like Ragna are to have any hope of dealing death to these seemingly invincible, fire-breathing beasts, they must find a way to level the odds. Ragna teams up with a mysterious man named Crimson who has likewise sworn to stand against the dragons menacing the world. But although Crimson’s motivations may be mysterious, his goal and Ragna’s perfectly align, and together they’ll fight to vanquish the dragons once and for all. Note: The first episode aired with a runtime of ~47 minutes.
