Ryuu stood in the middle of the training grounds, his expression mostly blank and cold as he regarded his fellow trainees. To be honest the boy figured most of them would be dead by next year, and that did not bother him so long as they each at least took out one Titan before their death. Right now, they were just finishing up their 3DMG aptitude tests to ensure that this batch was not a load of failures. Without the ability to move in all three dimensions; they were nothing but meat for the Titans. Ryuu had already faced this test and passed with flying colors, and as was noted by one of the soldiers running the tests; he was possibly one of the best at handling the gear that had passed through this training ground in a long time. The boy simply adjusted his mask a little bit, that very mask being a reminder of the hell he had experienced twice in his lifetime already. Two times too many for the boy. On the mask, which only covered his mouth and nose, was the large grin of a Titan; it was an odd thing for a human to wear and was certainly something that gained Ryuu a lot of odd looks from his fellow trainees. However, Ryuu knew exactly what it meant; this mask was a symbol to Ryuu and to the Titans. It showed that the very ruthlessness that they had shown towards his loved ones would be repaid back on their kind. 

As these thoughts raced through Ryuu's mind he stared straight ahead at the latest failure to attempt the test of the gear. This boy had been bragging about how he would slay the Titans, something about his Dad taught him a little known secret that would allow him to take out every Titan he saw. But this boy... no Ryuu could see it in his eyes and in his face. This little runt was simply lying to try to gain the attention of his peers, how pathetic. Deriving happiness from getting any sort of attention from your fellows was a sign of weakness, and yet so many humans seemed to embrace this practice with distinct pleasure. It stumped Ryuu, as the boy didn't feel that strong of emotions as is; only the particularly powerful emotions such as Love, Hate, Fear, Anger, and Sadness really punched through his inability to feel and touched the boy's soul. It has been this way for almost as long as Ryuu could remember, so he didn't question why. 

With a sudden thump, the boy in front flipped straight over and knocked himself out, failing the final test. So as he was unhooked and carried off to the wagon to work in the fields; Ryuu watched with grim satisfaction. That was one less weakling who would drag down the tactical efficiency of the entire military.
