So I Read This Thing Online 2...: Amorous Crimson.. So I Read This Thing Online, #2

Uchida Jurobei is no hero. He is a man fueled by a singular, boiling hatred for the S. E. A. S., the shadowy organization that orchestrated his sister's "accidental" death. To dismantle them, he has entered the belly of the beast, S. T. R. I. N. G.'s elite Marionette Academy. Having survived the brutal Battle Royal and received the "Blessing" (a potent genetic enhancement that pushes human limits) Uchida is stronger than ever.
But power attracts eyes, both admiring and lethal. Thus the lines between ally and enemy blur as a chaotic new player enters the fray, Captain Acidos Crimson, a brilliant, logic-defying pirate scientist with a literal army of robots and a dangerously warped obsession with Uchida. While Uchida attempts to navigate a fragile partnership with the emotionless, lethal Spiris, he finds himself caught between a pirate's jealous rage and a sudden, coordinated assault by "hooligans" who are far more than they appear.
