Dragon Century

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.

Four brothers with magical powers must use them to protect themselves and friends from an enemy bent on destroying them.

Faaren is a peaceful and happy realm, ruled by a wise King... until the Demon Lord Ackdam overruns the kingdom with his black legions and terrifying dragon, killing the King and capturing the Queen. But the King's young son, Sirius, is swept away to safety and grows to be a powerful young warrior, tutored in the ways of swordsmanship and chivalry by his father's loyal minion, Rias.

The story follows a fire-breathing, human-hating dragon raised by a mother cat in a forest. The dragon, known affectionately as "Uncle Wing," watches over the many curious cats — such as one that goes on an adventure with a human prince, and another that lives in the city and people-watches as a hobby — and gradually warms up to humans along the way.
