However, after the events in Celes, Fai seems to have gone back to the way he was at the beginning of the series, as he once again addresses Kurogane with strange nicknames, and he seems to give a real smile now.įai worries about his companions and would go as far as breaking his own personal vows to ensure their safety. Kurogane confronts Fai about this, and states that Fai should figure out what he's doing with his present and future, because his past has nothing to do with either Kurogane or their younger companions. Fai tells Kurogane that he should not worry or care about him, which Kurogane responds with 'I don't care about your past. So prepare your current self.' After Kurogane leaves, Fai collapses, emotionally exhausted, and states that this is too hard for him. When Fai's past is finally revealed, it's known that his real name is Yuui. It is shown that 'Yuui' was born in Valeria Country, with a twin named Fai. Though the birth of the second prince's son was highly anticipated, the birth of twins was considered to be a bad omen. Shortly after their birth, the second prince died, and their mother committed suicide out of guilt for giving birth to them.
In addition, the country suffered many misfortunes, and the twins, when combined, bore powerful magic that rivaled that of the current king.
