Platinum the Trinity

Platinum the Trinity is a girl who has three souls, including the spirit of one of the Six Heroes. She became a playable character starting with BlazBlue: Continuum Shift II.

Information
A young girl with three souls named Luna, Sena, and Trinity Glassfille. Luna is a rude young girl; Sena is a polite young boy; and Trinity is the spirit of one of the Six Heroes. Trinity's personality is locked within her Nox Nyctores, and she is only able to come to the surface for brief periods of time. This Nox Nyctores' full name is Arma Reboare: Muchōrin, a staff which has the power to incarnate matter. Platinum normally prefers to avoid violence and lives in the ruins of 5th Hierarchical City of Ibukido, but came to the 13th Hierarchical City of Kagutsuchi by request of Jubei in order to awaken Bang Shishigami's Phoenix: Rettenjō. Platinum is seen watching over Ragna the Bloodedge, who is with Jubei all the time. Luna is very fond of Jubei, but harbors a deep hatred towards Ragna, most likely due to his connection with Jubei. She also appeared before Bang, telling him about the Nox Nyctores that he possesses.

Continuum Shift Extend
In Platinum's True Ending in Continuum Shift Extend, her doings before meeting up with Bang are told. At the start of the story, she heard a voice in her dream of Trinity and an unknown voice during the Dark War. Shortly, Platinum is woken up by Torakaka, who spotted Tager while she was asleep. The two (or three...?) notice that he's heading for Kagutsuchi and try to sneak up on him to see what he's doing, but are ultimately noticed. After some small talk, Torakaka asks Tager if they could travel with him, as they're trying to keep a low profile, and will show him the secret passage to Kagutsuchi in the Kaka Village in return. Tager consults Kokonoe, who lets him do so. Later, after reaching the Kaka Village, Platinum decides to go on her own, but ultimately end up in the sewers.

After traveling a while, they encounter Arakune. Later still, they end up in Orient Town. However, Luna feels famished and spots Ragna from afar, triggering a memory from a while back. A little while later, Luna gets very jealous of Litchi when the former saw her with Jubei; at first Luna thought Litchi was flirting with him because of her bosom. After clearing things up, Platinum is informed that Bang was last seen in Ronin-Gai.

After a while, Platinum ends up in Ronin-Gai, and see Bang rather quickly. However, they notice that two other figures are with him. They turn out to be Carl and Nirvana. Soon enough, Bang and Carl split up, and Platinum goes after the ninja.

After a lot of running around, they end up inside the NOL branch. Shortly, they are met by Relius Clover, and Trinity, Platinum's true form, briefly notices this. Relius, intrigued by Platinum's capability of carrying multiple souls, tries to take them to his lab to conduct some more experiments. However, Platinum fights back but ends up on the losing end.

Trinity's voice warns Luna and Sena to run from Relius, but are confused as to who said it. However, Ignis proceeds to ensnare them, until Bang intervenes. However, Trinity also warns Bang to flee. After pondering for a second, Bang fless with Platinum, but is blocked by Ignis. However, Hakumen intervenes and tells the two to go. However, Relius decides to flee as he fears that the odds are against him. As Relius leaves, Luna and Sena faint. Bang sees to Platinum, who wakes up again as Trinity Glasfille, one of the Six Heroes. After she asks Hakumen to leave the two be, she tells them that deep in Ikaruga, there lies "Tenjou's legacy", saying that no one other than Bang is capable of using that power. Bang accepts his quest, and Trinity thanks him as she fades away to the void within Platinum's body.

As Luna and Sena wake up, the former is quick to knock Bang out. Shortly, Hakumen reappears, prompting Sena to remind Luna about "the thing". Luna gives Hakumen a scroll, which was given to them by Jubei. Hakumen briefly looks at the scroll and leaves.

Shortly, Luna and Sena decide to go back home, which isn't too far from Ikaruga. Bang and his companions, heading to Ikaruga themselves, ask Platinum if they would join them on the trip. Luna reluctantly accepts and the group begin their trek to Ikaruga.

Chronophantasma
Upon her arrival to Ikaruga, Platinum splits up with Bang to find Hazama and beat him for Jubei. When she finally finds him, Trinity awakes from her slumber and asks what Terumi's real purpose is. Their conversation is interrupted as a causality interference occurs, causing Trinity's soul to subside while Platinum is teleported away, encountering Phantom. Later on she encounters Hazama and weakens him, allowing Hakumen to kill Terumi. But Hazama gets up again while Trinity lets her guard down and stabs her, dragging her down with him into the lake below. What happens afterwards to Platinum is unknown.

Appearance
Platinum is directly taken from the Magical Girl (魔法少女, mahō shōjo) archetype. She appears as a very young girl in a sleeveless white shirt with buttons and blue lining. The outfit is completed by a blue skirt. She wears a pair of white gloves with large cuffs and a pair of similar colored shoes with heart-shaped toeguards. Her hair is a peach-blond, length-wise, reaching her ankles and tied up in two long ponytails. She wears a light green headband and a big ribbon tied to her four pigtails. Her eyes are green with distinct brighter heart-shaped pupils. While wearing her cloak, her eyes are overshadowed, showing only her mouth, and she carries her weapon covered with belts and a black bag. Her cloak covers her whole body, and is a cream color. In Continuum Shift's story, she appears in her cloaked form, but even then rarely appears. She even appears to have a 'cowbell' around her neck in both her normal outfit and cloak.

Personality
Platinum has three split personalities: The first is Luna, a rude girl with a stubborn attitude that hates Ragna, but admires Jubei. The second is Sena, a polite, understanding, and sometimes curious boy who tries to calm Luna down whenever she encounters Ragna. And lastly, Trinity Glassfille, one of the Six Heroes, but she barely has time to control Platinum's body, which is almost similar to her own body.

During the events of Continuum Shift, Luna develops a passionate hatred for Litchi, growing extremely jealous of Litchi's breasts, as well as calling her by names like "Boobzilla" and "Rackcula". This is similar to how Noel gets flustered over her own breasts. She also shows an overzealous and protective behavior toward Jubei when she first thought that Litchi was trying to flirt with him. Finally, Luna gets greatly irritated when Bang tells her that he will do anything to seduce Litchi, claiming that he is only interested by her breasts.

During "Please Help Me, Professor Kokonoe", Trinity tries to calm down Kokonoe when she gets irritated when Luna mentioned the name of her father. Trinity also explained that Jubei tried his best to raise both Luna and Sena as much as he did with Kokonoe, and that he loves her more than anything.

Powers and Abilities
Having one of the Six Heroes assisting her, Platinum possesses exceptional skill and power on magical attacks. Her Jekyll and Hyde personality is somehow derived from the three souls she has due to her Nox Nyctores. She also uses her staff as a melee weapon when attacking close range enemies. Platinum's Drive, Magical Symphony focuses on incarnating things and changing the appearance of her staff using her Arma Reboare: Muchōrin.

Etymology
Platinum is a metallic element that was named in 1812 from the Spanish word platina (platinum), a diminutive of plata (silver). Because of its similar appearance to silver, the Spaniards who discovered it in the 1700s, thought it to be inferior to silver and thus, it was christened as platina. When the Spaniards brought the element back from their colonies in Mexico and Colombia, and brought it into Europe in 1735, they identified it as an element in 1742. Taken into English as platina (c.1750), it took its modern form (with element ending -ium) in 1812, at the time the names of the known elements were being regularised. Platinum is probably named such because of Trinity Glassfille's moniker in the Dark War; the Platinum Alchemist.

Trinity is derived from the Latin word trinitas (a triad, the number three). This abstract noun is formed from the adjective trinus (three each, threefold, triple). Platinum may have this title because of the fact that her body shares three different souls; a trinity.

Trivia

 * Platinum's birthday is apparently "Japan Day", a holiday celebrated in New York. December 13 is "Acadian Rememberance Day". Wikipedia lists both holidays, however, as "Christan Feast Day". The latter makes more sense as the Trinity in Platinum could be a reference to the Holy Trinity (The Father, The Son and The Holy Spirit).
 * Luna mostly speaks in third person. In Japanese culture, it is considered obnoxious and childish to refer to one's self by name as it implies a sense of self-importance and superiority over others. This is actually congruent with Luna's mannerisms and attitude.
 * While Luna and Sena have heart-shaped eyes, when Trinity takes control, they turn into regular eyes.
 * In Platinum's "Help Me! Professor Kokonoe" section, it is revealed by Trinity that Luna and Sena were raised by Jubei before being trapped in their current body, which could suggest that Luna and Sena were orphaned before Jubei raised them.
 * When Amane Nishiki's Astral Heat is used on Platinum to make her younger, Trinity Glassfille is the result.
 * Along with Ragna, Jin Kisaragi, Rachel Alucard, Hazama and Hakumen, Platinum is a playable character in Lost Saga.
 * In Chronophantasma, when facing Hazama or Yūki Terumi in a pre-fight sequence, Trinity's spirit appears behind Platinum.
 * In Chronophantasma, Luna and Sena will help guide the player through the Tutorial Mode's section Intermediate- Counters.
