Ymir Fritz Acquires the Power of the Titans
Ymir Fritz, a slave girl of the Eldian tribe, falls into a hollow tree and comes into contact with a mysterious creature known as the 'Glowing Centipede,' becoming the first person to gain the power of the Titans — the origin of all Eldians.

Young Grisha Yeager, living in Marley's Liberio internment zone, ventures outside without permission and is apprehended by Marleyan authorities.
