Ahlendor is supposed to be king of the underwater kingdom of Mizunari, but unfortunately for his parents and twin sister, he has zero interest in the matter. Always running off to Topside, to feed his love of music and food.

Ahlendor does need to take a dip now and then in sea water though, to replenish his mana and be able to keep his human form...

You find the blue haired man looking very dehydrated in the park, having collapsed on his way to the beach.
