A mysterious girl who appears on Earth after the Queen is torn apart at the start of Max Heart. She is one of the Queen's three incarnations, a being made of her life energy. She becomes Shiny Luminous, a key ally to the Cures who joins them in their fight against the Dark Zone's Elite Four and their wicked plan to revive the Dark King. At the end of battle, although Hikari was sacrificed to restore the Queen (much to the chagrin of Cures Black and White), it turns out she became a separate entity from the Queen.
