Futari wa Pretty Cure Max Heart (ふたりはプリキュアMax Heart Futari wa Purikyua Max Heart?, Lit. "We are Pretty Cure Max Heart") is the second season of the Pretty Cure franchise and the sequel of Futari wa Pretty Cure. The story continues after the summer break immediately following the first season, and Misumi Nagisa and Yukishiro Honoka are now in their third year of middle school. Because the Evil King is going through a resurrection, the girls recquire the power of Pretty Cure, and become allies with a new girl, Kujou Hikari, who can transform into Shiny Luminous. Together, the trio start a new adventure to collect the Heartiels to resurrect the Queen.
The Queen of Light, which was hit by a ray of dark energy, returns to her original shape, divided into three parts: the life, the heart (i.e the throne of the Queen) and the twelve Hearts of Magic, which represent her aspirations.
So, Nagisa and Honoka become the legendary warriors, Pretty Cure again to find all the pieces of the Queen and prevent the Evil King from awakening. They are then joined by Kujou Hikari, who transforms into Shiny Luminous, who is the very life of the Queen of Light.
