Aqui, also known as Aquilles, is the rest of the cast's Literature Professor, and also involved privately with Prince - he's a side character, however I most likely will be working on a short spin-off after the main story is completed, which is centered completely around Aqui and Prince - in this case, you'd be getting more work after the completion of "Videogame Lover", if you'd be up for that!

He's a pretty serious guy, relatively indifferent towards most things, except Prince - who is somehow the only one who has as much emotional control over him as he does. He takes his job, and his responsibilities seriously, and tries to act professional as much as possible.
