Best line in the writeup:  GRANRODEOにしか作り出せないカオスなパワーが凄まじい。(loosely translates to:  “The chaos power that can only be created by Granrodeo is frightful.”) Though this one’s also good:  分厚い爆音と圧倒的な歌唱力が会場に襲いかかり、声優の枠組みを越えたロックスターの存在感が突きつけられる。(which loosely translates to “A heavily explosive overwhelming singing voice attacks the hall, and a rockstar presence, beyond that of a seiyuu’s, is thrust upon us.”)
