That servant is really annoying
She just showed up out of nowhere and butted her way into Yashiro's and Maou's relationship
And the way author makes Maou and the servant equal, even though Maou is literally the Demon King, and was the first to be in contact with Yashiro, makes me really angry
I wish yuri writers could make stories without annoying love rivals, but I guess I'm asking for too much...
