(Eren's POV) I alongside Mikasa were called to Commander Erwin's office at short notice and saw that he, Levi and Hange were looking at me with serious looks. Erwin : "Ah Eren and Mikasa the cadets that I was looking for. Please have a seat" Me : "Commander Erwin by all means, why did you called us here in the middle of training? ", I asked but Commander's answer was interrupted by Levi. Levi : " * his scowl deepens * We asked you to come here because you seemed that you hidden from us a secret about your other sibling.... the secret that he's mostly Titan. " (To be continued...) (I own only the changes in the plot and my OCs, Attack on Titan is owned by Hajime Isayama and the studios that helped to animate it.)
