Trinity Glassfille

Trinity Glassfille, also known as Platinum the Trinity and the Platinum Alchemist, was one of the Six Heroes and the former wielder of the Nox Nyctores - Arma Reboare: Muchourin. Trinity was the best friend of Nine the Phantom and a master of Alchemy, later becoming sealed within her own Nox and sharing a body with Platinum the Trinity.

Trinity first appeared in BlazBlue: Continuum Shift.

Central Fiction
Trinity left Platinum, and found her way to the Arcus Diabolus: Bolverk, transferring her soul to the weapon. She eventually switched into the Mucro Algesco: Yukianesa, and met Jin Kisaragi. They talked and she made a pact with him, using alchemy in order to make his body durable enough to fight – the only catch being that his body would eventually become completely unable to fight after an unspecified amount of time, but Jin still agreed to the terms. She was absorbed into the Embryo, but her memories were seemingly unaffected as she stayed by Jin’s side inside Yukianesa. Trinity became one of the chosen.

Eventually, she and Jin were transported to Ikaruga by Nine, who had told them both to kill Izanami to claim their piece of the Azure. She suggested finding Kokonoe, who could help them both in achieving their goals. Eventually, they found Platinum, whose existence had nearly disappeared. Thanks to Jin’s Power of Order, both Luna and Sena’s existences were perceived, if only for a while – Trinity herself was given a materialised body by Platinum, and she properly met them for the first time. The three of them later broke into a Sector Seven facility and retrieved data pertaining to Platinum’s body before escaping. She offered to adjust the body for Platinum, although doing so would mean that she would never be able to inhabit it again. Carl Clover found them, and offered to assist her so he could gain experience.

Platinum was now fully recovered and trio parted ways with Carl. They were by found Jubei and travelled with him to Yabiko after hearing of Nine’s hidden eleventh Nox Nyctores. Before they did so, however, they dropped Platinum off at the Kaka Village so she could be safe from harm, and gave her the task to materialise Hihiirokane before leaving her to her task. At Yabiko, she offered her expertise in alchemy to create a key that could be used to enter Nine’s workshop.

Trinity went as part of the strike squadron sent into Nine’s workshop. Inside, Trinity listened to Nine’s explanation of the world, the Prime Field War, her desire, and why she created the Corpus Sepulcro: Requiem. Ragna defeated Nine, and she, alongside the others, were assaulted by Izanami and Nu-13 but thanks to Nine’s use of the Radiance of Extinguishment to activate Requiem, they escaped but not before Trinity watched her best friend finally die.

Celica’s sorcery forced Rachel to teleport everyone out of the area to Celica A. Mercury’s Church‎ where Trinity chose to stay largely within Yukianesa without talking. She watched Celica die before she teleported back to Yabiko. Trinity watched Kagura and Jin battle Azrael and win, and then as the world entered the final stages of Doomsday, begging Jin to hurry and find the others. She watched as Susano'o was reborn in the world and when Hazama threw himself into the Boundary, his last words in the world remarking how much he hates her eyes.

In the exterior of the Embryo, Trinity helped Ragna and Jin defeat Susano’o, putting Jin inside the Unit after Ragna dragged Terumi out of it. She soon materialized clothes for Noel and took Jin out of the Susano’o Unit against his wishes. Trinity told Ragna that taking her dream would be impossible since it had already been realized, and she threw the Unit deep into the deepest part of the Boundary, thanking Hakumen for all he had done for her. Trinity’s spirit then finally passed onto the next life.

Trinity Glassfille
''A young woman who was enrolled in the Mage's Guild's school. Her distinctive skills and intellect earns her the name, 'Platinum Alchemist.'''

Konoe, who is later known as the Great Sage Nine, is her best friend, who Trinity supports throughout the Dark War as one member of the Six Heroes.

''She always approaches people with the benefit of the doubt, even knowing that they are a notorious criminal. Her kindness doesn't always work out to her advantage. Her gentle and optimistic smile, along with the tea she serves, can easily wash away any tension or stress from a long day.''

''Trinity undoes the the binding magic Nine cast on Terumi, after the Black Beast is defeated. But it didn't take long for Terumi to turn on her... She is cast into the Boundary with her friend Nine, according to Terumi's plan.''

She manages to seal her soul away in the Arma Reboare: Muchorin, and later finding shelter in the young girl, Platinum.
