Kingdom Hearts Desolation

Plot
Set 20 years after Kingdom Hearts 3, Kingdom Hearts puts players in the shoes of Niko, a young man training under Riku. After Sora and Co. go their separate ways, Riku, now a Keyblade Master, decides to become a teacher and teach the skills of the Keyblade warriors to others. He runs into a six year old boy by the name of Niko who is running from his home after it is destroyed by a dark sorcerer by the name of Herato. Riku decides to train Niko to use a keyblade to help him fight back. Cut 10 years into the future and Niko, now a strapping sixteen year old, wants to see the worlds. Although Riku denies him that chance, Niko gets his wish when a young girl calls to him from The Radiant Garden. He sneaks off, leaving a note and leaves. Upon getting there, he's introduced to the one who summoned him. Revealing herself to be Sora and Kairi's daughter, Serenity. Before Niko could ask any questions, they're ambushed by Herato and his horde of demonic creatures called the Desolate. Combining the fury of the Heartless and the sheer numbers of the Unversed, the Desolate were able to keep Niko busy enough that Herato was able to make off with Serenity. Before he could chase after them, Niko feels weary and tired and passes out.

He wakes up in Disney Castle near King Mickey who has a favor to ask. Sora, Donald and Goofy went after Herato after he attacked Twilight Town, but never returned. He asks that Niko takes Max and Daisy and go after the trio. Niko accepts this tasks and with the help of the Neo Gummi, the newest addition to the Gummi Ship fleet, Niko, Max and Daisy set off on an adventure of a lifetime!
