Gaelion (Spin-off)

Gaelion (ウィンディア) is a half-dragon and Wyndia's adoptive sister. They are saved by Naofumi Iwatani and Motoyasu Kitamura from slave hunters in Mirso Village.

Appearance
Gaelion has been described to look like a young dragon. However, she clearly has blood of other monsters as well.

Personality
Gaelion clearly loves both her late father and her sister very dearly. While she didn't cry like Wyndia, her father's death caused her to resolved to get as strong as possible - even if she has to become a demon.

Background
Gaelion is a monster who was raised by the dragon emperor named Gaelion. However, her father Gaelion was killed by Ren after he was manipulated by the greedy villagers in Mirso Village. Nearly all of her adoptive family was killed by the villagers until only her adoptive sister Wyndia was left.

Loop 5
Disillusioned by King Aultcray and Malty in Melromarc, Ren decided to travel east to Zeltoble. On the way, he passes through Mirso village where the villagers convince him to slay a dragon in the nearby mountains. He successfully kills the dragon and then continues on his way to Zeltoble.

The villagers then start ransacking the slain dragon's territory - looting treasure and killing all dragon-related monsters in the area. They also attract adventurers to help and charge money to see the slain dragon's corpse. When Naofumi and Motoyasu arrive, they investigate to find the villagers about to capture the devastated Wyndia and her adoptive sister. They use their influence to save the two. After briefly grieving at their father's corpse, the two then decide to join Naofumi and Motoyasu.

Trivia

 * The Gaelion in the spin-off series is a different animal from the Gaelion in the main series. This Gaelion is a half-dragon who was likely hatched before the heroes were summoned while the Gaelion of the main series is a full-dragon boy who hatched months after the heroes were summoned.
