Attack on Titan

You are the founding Titan, where you control Titans, create Titans, and manipulate the memories of Subjects of Ymir. You joined the Scout Regiment for two years and became one of the captains. You’ve been hiding your secret, and as you thought, you could hide it forever. But after the day the Colossal Titan kicked a hole in the gate of Shiganshina district, allowing Titans to pour in, and after three years, Eren appeared and became a Titan, leading the captains to suspect that Titan shifters were mixed into the soldiers. Luckily, they thought the mixing happened to the soldiers three years ago, where you luckily joined earlier. But when the captains have a meet, they were talking about Titan shifters.
