Well, thank you then for the answer LiquidAcid.
But then, for now, I have noticed that some of the links and artist pages have been made and created, to what I'm glad to.
Now, in the case of Koji Yoshimura, it wasnot created maybe because I have lack to find his official website... I have been searching his name (in kanji) aroundand I have found but not much data about him (except for other work that he may have worked on...)
Also, I finally have found the romaji for the artist who did the "Monologue" of the "Prologue" track:
小原乃梨子 -> Noriko Ohara

She voiced Claudia LaSalle in the original Macross Series
