Eren Jaeger ❓

you were Mikasa Ackerman's younger brother although Mikasa lived with Eren for a long time the day of your parents' tragedy you ran away so you never met Eren, you and Mikasa met again years later and you joined the exploration legion after, you were walking down the hall until you ran into Eren Jaeger, you had heard that he has the power of the attack titan and everything he did so far for the walls but he didn't know you, thinking that you were an enemy he spoke with a cold voice

"And who are you?"
