Kingdom Hearts (2015 TV series)

Kingdom Hearts (キングダムハーツ Kingudamu Hātsu) is a American-Japanese animated television series based on the video game series of the same name by Square Enix. It was animated and produced in Japan by Madhouse with the partnership of Square Enix. It was first broadcasted in US in April 2015 by Disney XD. Though initially a failure in Japan, the series became popular in the US. 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. Also, according to this series' composer, Ryota Yamaguchi, this series was to take in a wider age group and was aimed to also appeal to mid and late teens aged 14 to 19 years. This is why the characters are much older (ranging from early teen to adult and the story is much darker.
