This is so good. The usual tied in the past Ereri story but still I like how it ends. I mean Eren in the anime, we know how he wanted to go outside the wall and see the ocean, and that was like the assumed ending of Shingeki no Kyojjin. Somehow, I got the feels while reading this, the same feels when I watched the anime.
Levi has flashbacks of his past life as a titan hunter. Together with the doctor they go to an island to find fragments of his past. There they meet Eren who lives there with his father.
