This is based on J05H (   / channel  ) video of chapter 122 of Shingeki no Kyojin manga motion with this song playing on the background.

The song is Light & Shadow composed by Hiroyuki Sawano, created to League of Legends, but it fits well with AoT, since it's the same compositor.

I do not own nothing, I just edited the song with the episode, doing an anime version of J05H's video.
