It's "losing" and "lose" not "loosing" or "loose". You also might want to put that in quotes in the summary, lest your readers think that you, dear author, are "loosing" your mind. The super-runon sentences are quite effective in conveying Setsuna's insanity, so I'm going to assume you put them in intentionally. This is obviously not the Pluto who begged Beryl to turn her hatred back into love (in the Sera Myu song Onna no Ronsou), and it's interesting. "and know I can't do" should be "and knowing I can't do".. it fits with the "watching it change". Why does she think that "someday Sailor Pluto will live again, without the isolation but with eternal peace." ? My understanding is that the personality of Setsuna is but a variation on the timeless soul of Sailor Pluto, so she can't really escape her fate to guard the Time Gate in my understanding. Even assuming a different Pluto is called, why should she be any less isolated than Setsuna?
