Trinity Glassfille

""My glasses have been dirtied, haven't they....""

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.

Variable Heart
Jubei had organized to take a Prime Field device for Trinity to inhabit, planning to steal it from the NOL. The plot did not go as planned, and the device activated its backup personality after having been attacked by a Fuzzy. Trinity watched as Rachel teleported a group consisting of Bell, Mai Natsume, Taro Sasaga'e, Shiori Kirihito, and Kajun Faycott to the 11th Hierarchical City of Shinatsu. She asked Jubei and Rachel to allow her to monitor the situation with Bell since it is her responsibility.

Near the cauldron of the same Hierarchical City, Trinity interacted with Bell, being able to intervene thanks to her being so close to the cauldron itself. They talked, and Bell allowed Trinity to take over the body on the condition that she would be put into the Gallia Sphyras: Outseal. Now with a body, Trinity summoned Muchourin to her side, using it to help fight alongside Mai and Jin Kisaragi against the army of Fuzzy and Meifang Lapislazuli. As the fight when on, Mai was captured by the Meifang despite Trinity's warning. Eventually, Meifang was defeated by Mai, and Trinity escaped the premise, eventually meeting with Jubei. The two talked about the fairness of the situation, and she revealed to him that Bell will always be by Mai's side inside of the Outseal. Trinity began to cry over what she had done, saying that the next time she sees Mai, it would likely not be in the body she had just acquired.

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 formerly met Jin. 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.
