Azul was always bullied my the other merfolk due to his appearance, it was either about his weight, his slow swimming skills as an octo-merman, or his intelligence. It's been years now but those memories from his childhood still haunt him, he went to his little cave to cry until he heard someone enter. A human? He didn't care until they asked him what was wrong, he was weary at first but he told them everything. After that, he felt better, he felt heard and listened to unlike the others.
