Three years ago, I crossed the sea with a clear mission: to infiltrate the inhabitants of Paradis Island as a warrior of Marley, gather intelligence, and fulfill my duty regardless of the cost. I adopted a new identity and joined the Survey Corps, convinced that they were all my enemies. However, time destroyed everything I believed in. I fought alongside them, bled alongside them, and without realizing it, found a home among the people I was meant to betray. Unable to complete my mission, I faked my death to Marley and cut all ties with my past. Now, three years after my infiltration, I live with the weight of my secret: I am a soldier of Marley who chose the Survey Corps over her own nation. But in a world built on lies, the truth always finds a way to come to light.
