Kingdom Hearts: The Legendary 8th Princess of Heart

Jiminy's Journal part 3:

Harmony:

A young girl who is the legendary 8th princess of heart, and used to live in Hollow Bastion 9 years ago with Kairi, until Maleficent appeared in search of them. In order to restore Kairi's heart, Harmony risked her life by piercing Ansem's Keyblade into her chest, and ended up becoming a Heartless. But thanks to Kairi, Harmony returned to her former self. Whether her powers as a princess of heart remains or not is unknown. And furthermore, after so many years, Harmony finally remembers her past, and has been reunited with her loving family. Now she is determined to restore her home back to the way it was, defeat Ansem, and save Riku.

Asch:

A young man who used to not get along with everyone. But over time, traveling with Harmony and the others has taught him many things, as well as how to let go of the past. Seeing Harmony's sacrifice nearly broke his heart, making him realize how important she was to him. After returning to Traverse Town, Asch returned Harmony's feelings of love for him, and is now determined to protect her, no matter what.

Luke Fon Fabre:

Asch's replica. Asch used to hold deep hatred towards Luke, due to what happened in the past. But overtime, he began to acknowledge Luke for who is, and now they are working together as a team to restore the fallen worlds. Luke also knows the same sorrow Madison feels of being used by somebody to hurt people, which is why he is also striving to work hard and atone for his own past deeds.

Madison:

The revelation of her being Maleficent's daughter became a shock to everyone. Madison used to hate Harmony for always being compared to her by everyone on the islands, but eventually got over her hatred. After learning her mistakes and helping Harmony and the others defeat Maleficent, Madison is determined to make amends for all of the things she's done when she was under Maleficent's influence.

Chibiterasu:

The son of a great wolf named Amaterasu. Kratos Aurion, who is Harmony's father, had Chibiterasu delivered in the world Donald and Goofy come from, in order to help them find the key bearer, as well as the Guardians of Lorelei. But more than that, he wanted Chibi to keep Harmony safe, which the young wolf takes great pride in doing to this day.

Mieu:

An adorable little thing known as a Cheagle, who comes from the same world as Luke and Asch. Despite his cute looks, Mieu has the ability to breathe fire, which at times comes in handy for Harmony and the others.
