Gundam F91 has an emotional ending, and Hiroko Moriguchi's song is about remorse. I don't know anything about Gundam, I had to look it up, so if anyone here can provide some more information, please feel free to do so.
On page 5, there is kind of a joke that gets lost in the translation. Hiroko Moriguchi literally sings in rough English, “Pray don't break a peace forever.” However, Eiko does not say this in English but tries to Japanize it.
ぶれいどん / ぶれいか / びそえばー!
