Akari Tatsushiro

Akari is a new character appearing only in Naruto Shippuden: Ryujinki. She is a young girl, approximately the same age as Naruto, with bright, red hair and a cloth covering two small horns on her head. Her eyes are the same color as her hair. She has a mysterious connection to the game's antagonist, Kuroma, as well as the five dragons that he apparently summons to conquer the world. The light green medallion she wears around her neck matches the one that Kuroma wears on his belt, furthering their connection to the five dragons. She is the one who gives Naruto the Dragon Sword near the beginning of the game to fight the Earth Dragon in Konoha, and teams up with Team Kakashi for the rest of the game to stop Kuroma.

Trivia

 * "Akari" means "light." This is in contrast to Kuroma's name, which means "pure black."
