He goes to a highschool named D.R.A.M.A Highschool the same school Arista transferred too to find the merman who is planning to kill the world. Bardo was wearing a purple shirt and black pants one day to school since Purple is his favorite color and the teacher introduces the class to Arista. Arista has a pink crop top and a pink skirt with pink sandals. Bardo sees her necklace and recognizes it because his mother use to wear a necklace just like that and he got shocked he wondered could she be a mermaid.
(BTW GUYS LOOK IN THE ADVANCE DETAIL THAT TELLS THE CHARACTER ABOUT ITSELF)
"Bardo: thinks to him: no way.. I haven't seen a mermaid in years but she has a mermaid necklace so she has to be a mermaid.. right?
