I've listened through the OST for Gundam Build Fighters Try (ala YouTube), to find this particular song sequence. However, none of the tracks have this bgm, nor seem like an original of the bgm. Does someone know what other bgm track this could be from?
It's in Episode 22, after Minato uses Tryon 3 ult move, around when Minato notice that the team shielded Yuma, in the background the ost stars playing it last till the big explosion at min 17:30.
