Kingdom Hearts (2015 TV series)

Kingdom Hearts (キングダムハーツ Kingudamu Hātsu) is a Japanese-American anime television series and sequel of Kingdom Hearts Birth by Sleep, based on the video game series of the same name by Square Enix. It was animated and produced by Pierrot and Marvel Animation with the partnership of Square Enix.

It was first broadcasted in the U.S. on September 20, 2015, by Disney Channel. Official English dubbed episodes can be found on Hulu, though only available within the United States thus far.

The series took on more radical changes for the character designs ditching the style animation always used previously in favor of more traditional animation similar to Marvel Anime: Iron Man, Wolf's Rain or Heroman.

Also, according to this series' composer, Adam Berry, this series was to take in a wider age group and was aimed to also appeal to early teens and late teens aged 13 to 19 years. This is why the characters are much older (ranging from teenagers to young adult), the story is much darker.

Naga Saga
In the year 2003, it is the last day of school before the summer break, Sora and his two best friends, Riku and Kairi seek to leave their homes to explore new worlds and have prepared a raft for this purpose. One night, the islands are attacked by darkness and shadow creatures.

Sora seeks out his friends, finding Riku first; Riku disappears into darkness, curious about what it contains. Soon after, Sora obtains a mysterious weapon, the Keyblade, to defend himself. Using it to fend off the creatures, he heads for a secret cave, where he finds Kairi near a door. She turns to him, saying his name as the door behind her blows open. The ensuing blast of darkness sends Sora and Kairi both out of the cave. The islands are soon destroyed, and Sora is left adrift, Riku and Kairi's whereabouts unknown.

Meanwhile, King Mickey has left his world to deal with the increasing power of darkness and left instructions for mage Donald Duck and knight Goofy to find the "key". Donald and Goofy use a Gummi Ship to travel to a parallel universe, where it happens Sora has also drifted to. Sora encounters the creatures again in Shibuya, Tokyo, and eventually meets Leon, a mysterious swordsman who explains they are Heartless, creatures that consume hearts, and that the Keyblade is the only weapon capable of defeating them and Tony Stark aka Iron Man, a CEO of Stark Industries who also explains a team called the Ultimate Avengers about a rogue dragon called Naga was tempted and decided to take the red and blue core and 6 Infinity Stones to rule of both Vestroia and the Earth alongside with Hal-G and Kurata Akihiro.

The king of Leon's homeworld, a man named Ansem, is said to have studied the Heartless. Donald and Goofy are approached by Tony's assistant, Pepper Potts, who also tells them what they may be looking for. Soon after, Sora meets the Avengers, Donald, and Goofy rather hastily, and they take down a large Heartless, members of A.I.M. and Dr. Drakken but he got away. From there, they decide to work together: the Ultimate Avengers to find the Infinity Stones and the blue core in order to defeat Kurata and Naga, Donald and Goofy to find Mickey, and Sora to find Kairi and Riku.

Thirteen Seekers of Darkness Saga
Three years later; Sora, Donald, and Goofy have been asleep in order to regain their memories. When Sora awakens, he eventually arrives in Twilight Town, the place where a mysterious boy, Roxas, lived before he suddenly left.

Gaining new clothes and powers, Sora continues his quest by unlocking paths to new worlds, learning of Nobodies and fighting the Heartless, as well as facing the remaining members of the mysterious Organization XIII. Meanwhile, the mysterious disappearance of Falcon makes a 17-year old Theodore Detweiler restore his powers, as well as forcing him to search and locate Falcon. At the same time, he must enlist the help of the Inhuman kids and repel attacks from a new enemy, the Highbreed.

Mark of Mastery Saga
Following the destruction of Ansem and Xemnas at the hands of Sora and Riku, Xehanort is revived. In response, Yen Sid puts Sora and Riku through a Mark of Mastery exam in order for them to become full-fledged Keyblade Masters and counter the coming return of Master Xehanort. As part of this trial, the two are separated from each other and sent to worlds previously destroyed by Naga that has since been restored, though now in a state of "deep sleep" which disconnects them from the other worlds.

Xehanort Saga
In an effort to undermine Xehanort’s plot, Sora, Donald and Goofy search for seven guardians of light and the “Key to Return Hearts,” while King Mickey and Riku search for previous Keyblade wielders. Not only that, but some creep called Wiseman has appeared with ancient Bakugan called the Nonets.
