Music video
Jiyuu no Daishou [Theatrical Size] was a music video included in the LE featuring the animated sequence from Attack on Titan Part 2: Jiyuu no Tsubasa for which Jiyuu no Daishou was created.

Trivia

 * The LE packaging features one of the walls, with different sleeves featuring an open gate, a gate blocked by a boulder and a gate blocked by a hardened titan.
 * It is implied Revo can transform into a bird, as it is shown in the packaging and the Guren no Yumiya music video, heard in the first bonus song, and referenced in 14 Moji no Dengon lyrics.
 * The title "14 Moji no Dengon" is a reference to a Sound Horizon song, "11 Moji no Dengon", which also features a dying mother leaving an ambiguous message to her child.
 * The full version of Seishun wa Hanabi no you ni features a lyric about a nighthawk, which was the main motif of a Sound Horizon single about a band from a parallel world, just like Attack on Titan: Junior High is a parallel world to Attack on Titan.
