トリニティ＝グラスフィール

Trinity Glassfille was a member of the Six Heroes, and the true form of Platinum the Trinity who had her soul sealed within the Nox Nyctores, Arma Reboare: Muchourin.

Trinity is a very kind, cheerful and easygoing young woman. She was a good friend of Konoe A. Mercury, and was also quite close to Kazuma Kuvaru. She was shown to be affectionate towards him. However, she is strict when it comes to manners, and can be very frightening when angry. When Celica and Konoe inadvertently spilt tea over her, her gaze alone rendered them so scared that they ceased the quarrel, regardless of Trinity's usual smile.

After Terumi's betrayal, Trinity harbored immense guilt for Konoe's death and the repercussions that followed soon after to the point of being brought to tears while apologizing to Celica for what she had done.

In Central Fiction, she supposedly removed herself from the Muchourin in order to save both Luna and Sena from the injury Terumi inflicted on them in the finale of Chrono Phantasma, and is now tagging alongside Jin.
