1) Aciano is a Spanish word for Cornflower or “Centaurea cyanus”.
3) He’s basically MMA/Krav Maga free stylist with a preference for wrestling and grappling moves with above-average skill. In regards to swordplay, it would be more flashy and power-oriented mix of Kenjutsu and German Fencing with an advanced application.
4) Unarmed examples would be Grip vs Karma from Assassination Class Room (fight basically summarizes most of the Aciano’s strengths and weaknesses as a fighter) and Karl Vastor vs Mace Windu/Luke Skywalker from Star Wars, with Aciano standing for Grip and Karl Vastor. While his swordplay and tactics would be most similar to Darth Malgus, with the Alderaan duel with Satele Shan being the best example of it.
