Attack on Titan (literally translated as "Advancing Giants") is a Japanese manga series, and now an anime, originally written and illustrated by Hajime Isayama. The story centers around the lives of Eren Yeager, his adoptive sister Mikasa Ackerman, and their friend Armin Arlert, who live in a world where the remnants of the human population live inside cities surrounded by enormous walls due to the sudden appearance of the Titans, gigantic humanoid creatures who devour humans seemingly without reason.

Raku Ichijou is an average high school student. He also happens to be the sole heir to the head of a Yakuza Family called the Shuei-gumi.

The story centers around five Japanese high school students who are too young to be called adults, but who no longer think of themselves as children. Wakana Sakai once took music lessons, but she withdrew from music after losing her mother.

Yuki Hase, a high school boy, is concerned about a girl of his classmate, Kaori Fujimiya. She always stays alone and never tries to become close friends with anyone.
