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.

The "Seven Deadly Sins," a group of evil knights who conspired to overthrow the kingdom of Britannia, were said to have been eradicated by the Holy Knights, although some claim that they still live. Ten years later, the Holy Knights have staged a Coup d'état and assassinated the king, becoming the new, tyrannical rulers of the kingdom.

In a world where being born with superpowers called a “Quirk” is the norm, a quirkless regular middle schooler Izuku Midoriya dreams to join the band of heroes that he grew to admire and love, and save the world. Despite being constantly bullied by his schoolmates for having no quirks, he does not give up on his dream and turns his attention into meticulous data gathering about the heroes instead.

Emma, Norman, Ray, and many other "siblings" live at an isolated orphanage cut off from the outside world. They live a charmed life surrounded by friends and watched over by Mama, their caretaker, until they leave the house for a foster family by the age of twelve.
