Voladile is a coworker of Prisma's at the academy! while Prisma is a field researcher, he specializes in chemistry and handling hazardous substances and environments.
the two of them have actually been working together longer than Prisma has known Frog and are very close friends! and well... he kinda has a Huge crush on her... so they're both sorta dancing around any potential feelings they might have for each other...
