English translation
I destroyed the huge mecha and quickly escaped that strange dimension!! But as I got outside it was as if decades had been passed...!! "What is this?" The broken enemy mecha had withered away already, disintegrating like sand on the wind blow... What I saw when I got back to Earth was an "empire" built by the aliens!! At least 505 years had passed since the battle!! That strange dimension was a space-time rift... It probably was...!!
