【3DS】『PROJECT X ZONE 2』 主題歌＆OPアニメーションカット
Project x Zone 2's opening, "Sekai ha Hitotsu no Budai", sung by Marina at TGS2015 https://en.wikipedia.org/wiki/Marina_(Japanese_singer)
Previews some scenes from the opening, probably cutting out some of the unrevealed characters. Either that or it's actually incomplete, but the real version will supposedly have 2 full minutes of every available character in the roster shown.
