Originally Gijinkas for tubes of paint (https://www.dailymotion.com/video/x5qo3d5) that later got newer and much different designs to the point that only Akva barely resembles his inspiration. Akva has become a Distressed Dude with Rosita saving his life all the time. It's quite funny how this went down. They were made in the same year Horatio and Ana were so it was quite offputting I made characters so soon. Their lore is shorter because I didn't know how to say that the story focuses on Akva being captured all the time and Rosita and the others saving him.

LORE:

Akvamarin Chernikov (or Akva for short) had a surprisingly dark past for an upbeat cheerful musician. He lost his parents after his first day of first grade. Ever since then, Akva had been in fear of his life. He no longer eats red meats, he often is afraid of walking alone at night and he had no other attachment to anyone else outside of Rosita until he turned 20 years old where the person that killed... no ate his parents in front of him had tried to eat him next. Akva learned from every medical professional he has met that there was a reason he lost his family so early on in his life: He has a condition that makes him not just edible to demons, but particularly delicious and nutritious.

Rosita Sekvoya is one of those medical professionals. Although a bit of a prodigy on the subject, she suspected it when Akva struggles to sleep at night. She was able to get an education to help her learn how to help him thanks to a rich family but this rich family frowned upon Akva, who they deemed as another stray pup that Rosita picked up as a child that she grew fond of enough to prioritize. Rosita's kindness and patience was why Akva fell in love with her in the first place. Though, that kindness and patience could thin when it came to Rosita's mother, who hired a bodyguard for her despite the fact that Rosita herself had learn how to defend herself a long time ago.

Rosita and Akva left for America after Rosita witnessed Akva being bullied by others for his sensitive nature and for his passion for music being different than others, and of course when Akva's traumatic past caught up to him and ruined his would be first performance in public. In America, Akva befriended the Kuwabara Demon Hunters, as well as Boxer, Atif, Horatio, and Ana. It is because of these guys Akva has felt more welcome and safe in America, as Boxer even defeated the monster that has hid under his bed all this time. However, Akva and Rosita have one more beast to confront before they feel safe for real this time and like the weeds in a garden, he often comes back hungrier than ever before.
