Yeah, because they're doing a job. It's like having a control room and when combat occurs, it appears on the map and a Guard is dispatched there. Rape/sexual assault does not deal any HP damage or count as a combat action, because it wasn't even possible before the Catastrophe and thus doesn't show up on the Royal Guards' detection system. Isami drew her sword and cut the person, making them bleed/take HP loss, which counts as a combat action. Guard is summoned.

And obviously they're going to act differently once they're outside of their suits. Enbart's entire motivation is that he hates being treated like a mindless object and doesn't think that he (or the Royal Guard) are getting the respect they deserve. To quote from volume 6: "The proud guardians who protected Akiba. However, they weren't honored. They were scorned as pseudohuman automatons. Although their abilities surpassed even the Adventurers, their status was, at best, security devices, and they were essentially treated as nothing more than accessories for the town. They were a tribe of dogs. Truly a clan of slave-warriors, offered up by sacrifices, just as the characters in the name Kunie implied."
