What is the name of the song that plays at ~7:25 in Episode 18 of Try?
Jumped the Gun(dam) here. Show finished Airing 4/2015, and looked for OST around then. OST was released in Dec-2014. However in 2015, a Second OST was released. Found the track: "New Dimension Overlord Flow".
Interesting that the 2nd OST isn't listed on Gundam Wikia.
