Also known as: 黒いコート
The black coat is an attire used in the KINGDOM HEARTS videogame series. It is an article of clothing imbued with magic that protects the wearer's heart from corruption when traveling through the darkness between worlds.
The black coat is better known as the uniform of Organization XIII, though it has been worn by other characters who narratively predate that group, such as the Master Of Masters and Luxu (Kingdom Hearts).
