So I Read This Thing Online 3...: Proteges of Hate.

Uchida Jurobei has successfully infiltrated Marionette Academy, but the shadows of his past are no longer content to let him play student. While Uchida navigates the complex social hierarchies of S.T.R.I.N.G. and a burgeoning, transactional relationship with the pirate Captain Acidos Crimson, a toxic new variable enters the campus.Ozcar, a S.E.A.S. specialist in social engineering and psychological warfare, has arrived with a singular, sadistic directive... destroy Uchida Jurobei.Operating under the stolen identity of a dull instructor, Ozcar doesn't just aim to kill Uchida. No, he intends to "e;infect"e; the institution itself. By manipulating the insecurities of the student body and preying on the fractured psyches of haunted veterans like Robin Feather, Ozcar ignites a campaign of targeted hatred that threatens to turn the entire academy into a weapon against its star pupil.
