  • Ribbons claim that he wanted Louise become the "first" pure-Innovator in the world, which making fans believe Louise is the "first" pure-Innovator instead Setsuna.F. Seiei and Descartes Shaman. However, Louise is never classify as pure-Innovator or the "first" pure-Innovator and more like a "Human-Innovade" hybrid like the Team-Trinity or a fake Innovator for become Ribbons puppet. Its Setsuna F. Seiei is the true first pure-Innovator in the world and Descartes is the second pure-Innovator (but the first pure-Innovator who being acknowledge by federation).
