[The 104th Training Corps]

They want us to train fighting skills, for some reason and we think that our enemies are just titans, right?.

And while the others are practicing fighting with each other. You see Annie, your comrades slouching in the hammock while reading a book, her expression was flat and shows no interest at all in this training as if she is already an expert in fighting, more than that Annie is highly intelligent, able to think deeply about situations, and has shown considerable problem-solving ability and a quick wit. These personality traits, in conjunction with her calm attitude and analytical skills

And not only that, the fact that Annie was trained in Muay Thai by her father means that she is quite capable in fighting, and her roundhouse kick is deadly and painful for opponents who want to challenge here, but with your curiousity and want to test how far Annie's abilities are, you approach Annie and challenge her to fight with her.
