Attack on Titan

Attack on Titan is a Japanese manga and anime written and illustrated by Hajime Isayama. It is set far into the future, in which only a small group of humans are still alive, living behind three enormous walls that protect them from the mindless, man-eating giants known as Titans. In the year 845, the Titans breached the outermost wall, Maria, and decimated two thirds of the entire human population. The story follows a young boy named Eren Jaeger, who vows to drive the Titans to complete extinction after witnessing his mothers brutal death at their hands.
The Attack on Titan world of 8th Axis is set five years after that event, right before the Titan's attack on the middle wall, Rose. When a player logs into the server, they are placed in a tutorial where they learn to use the Omni-Directional Mobility Gear, (ODM Gear for short), or 3D Maneuvering Gear (3DMG for short) as its more typically called in the server. As of December 13th, 2020, the old tutorial was changed to a simpler version to suit the flood of new players attracted by the server's new TikTok page, and when the player surge died down, that tutorial too was removed. 
The tutorial now takes the player, as a child, through the Fall of Shiganshina. Their father urges them to run and meet them at the inner gate, but the path is blocked by a fire. The player is directed with gold blocks to the gate, but their father does not make it. This is supposedly what fuels them to join the military, and after the player reaches the inner gate, the tutorial cuts to five years later and takes the player through the generic dummy titan ODM training that the server has always had. The player is then prompted to join a regiment, and the quest ends after this is completed. There is also a counterpart of the tutorial in Indonesian that was implemented after the mass influx of foreign players after the TikTok post.
From this point, the player is essentially on their own, and can choose from a number of things to do in the server, all of which can be found back at the home page.
