I don't remember the other characters clearly, but I like Dijia, the strongest soldier in the dark.
Dijia was originally a dark warrior, but was inspired by pity and turned into light. Later, in a monster attack, Diga was resurrected on the ancient players and became a member of defending mankind.
Archaeologist Diga is also a warm-hearted. Although he was neither clever nor strong, he accepted his fate and finally proved to people that Diga's strength came from courage.
Therefore, Diga Altman is also known as the giant of light and one of the most familiar Altmen for mainland audiences.
I hope my answer is helpful to you!
