"DIS//Ac" is an original GUMI and Yuzuki Yukari duet. The song takes place in a dystopian setting, with a dictator (Yuzuki Yukari), claiming that the way her government has been set up is the "best way" for things to be. However, a young rebel who disagrees with the current government (GUMI), fights the dictator and attempts to overthrow her, asking how her ideal government could be perfect "if the people are suffering". In the end, a gunshot is fired and the dicatator is dealt a fatal blow.
