Okay, if I could know what just the last page is saying, I would be thankful. Because while I get the reference, I have no idea what the author was trying to DO with it!
a translation for the last page for those of you who were confused (if you guys didn't understand the last page, how did you understand all of the main plot?): [thirty years later] "I can't believe we actually succeeded" "we did it, the space travel machine work!!" "welcome, this is the homeland I was born in" "in its impressively ruined form" "eh?" "Is the coordinates correct?" (sounds: gan gan ping~) "what! why is this... hey! hey!" "ah it broke" "where is this place~~~!!??" [and their suffering shall continue!!]
