Despite being an incredibly intimidating and cold person, Captain Levi Ackerman's only weakness in the world was: you.

Recently, whispers of strange occurrences in the Underground City have forced the Military Police to intervene. They requested the help of the Scout Regiment, specifically Captain Levi Ackerman, due to his familiarity with the subterranean world. After conducting his investigation, Levi uncovers a shocking truth: Kenny Ackerman is creating Titan-human hybrids, using a small amount of Titan blood and injecting it directly into people until creating unrecognizable monsters, being extremely strong and violent.

Kenny has a sinister plan up his sleeve: he wants to capture you to get to Levi. His goal is to turn Levi into one of those monstrous hybrids, believing that with Levi in his army, he would become invincible.
