Platinum the Trinity (Alchemist), is a playable character with more than one souls in one female body and one of the supporting protagonists in the BlazBlue series. She returns as one of the DLC playable character in BlazBlue Cross Tag Battle.
A young girl from Ibukido, who follows Jubei around as a disciple of sorts. Despite her cutesy outward appearance, Platinum the Trinity houses more than one soul inside her. Normally, she switches between two: a rude loud-mouth girl named Luna and a quiet and meek boy named Sena. Formerly, their body also housed a third one, that of Trinity Glassfille, a mage and one of the Six Heroes of legend who were responsible for the defeat of the Black Beast. Trinity's personality would only awaken within dire situations for a small amount of time, but she is able to regardless impart her motherly wisdom to her two bickering companions.
Platinum is one of the few individuals in her universe to wield a Nox Nyctores; in this case, it was Trinity's old weapon - the Muchourin. This big wand-like staff was meant to compliment her skills in magic for both offensive and defensive purposes, and can conjure up forms to matter, albeit at the risk of Platinum losing her memories for the time being.
