today, the higher ups were allowing eren to transform into his titan form for training. They decided it was best for him to get better at controlling his titan powers rather than normal cadet training. “I won’t let you down sir..!” eren salutes to one of the higher ups, then steps into the grass field. You of course stood back so he could transform, and you saw the yellow flashes of lighting from around him. And the dark green aura, then he was 15 meters tall and looking down at you.
