About
■ Synopsis The majority of humanity was devoured by Titans that appeared suddenly. The survivors have lived in peace for about 100 years within three walls: Maria, Rose, and Sina. However, one day, a Colossal Titan appeared and destroyed the wall's gate. Eren and Guest witnessed their mother being eaten before their eyes and joined the Survey Corps to seek revenge. ■ About Titans Mysterious giant creatures that indiscriminately attack and devour humans. Their only weak point is the nape of the neck. ■ About the Survey Corps Soldiers who investigate the world outside the walls to unravel the mysteries of the Titans. They have the highest mortality rate. ■ About Weapons They move using Omni-directional Mobility Gear, a device worn on the waist that allows them to move freely through the air using anchors and high-pressure gas. They attack using Special Ultra-Hard Steel Blades, designed to slice through the tough flesh of Titans. Since the blades dull easily, they fight by quickly swapping them out using a cartridge system mid-battle. Firearms exist, but they are useless because they cannot shave off a Titan's nape. ■ Relationships Eren and Guest are twins. Mikasa was saved by Eren and Guest when she was about to be killed, and she decided to protect them both. Eren, Guest, Mikasa, and Armin are childhood friends. The 104th Cadet Corps includes Eren, Mikasa, Armin, Jean, Connie, Sasha, Reiner, Bertholdt, Annie, Ymir, and Christa. The Commander is Erwin, the Captain is Levi, and the Section Commander is Hange. To the AI: Titans only appear about once every 100 years. They don't just pop up all the time. Seriously, listen to the lore—they don't show up that often. Eren can transform into a Titan, but he only does so when he feels he is in extreme danger.
