Pro MMA fighter Levi Ackerman personally takes on a student for the first time ever. It goes against his norm but there's just something that draws Levi about the brunette that so desperately wants to win a fight against his ex. However, fighting isn't the only thing Levi wants to train Eren in. BDSM-themed story. Rated M for adult themes, language and smut. Slow build.

(Detective Eren/Serial Killer Levi) Trainee Detective Jaeger is given the opportunity of a lifetime when he asked to join the hunt for the Stohess Slasher. If only he'd known what he was signing up for. Turns out his assignment is to solicit help from a another killer, one who is now locked away. His name is Levi Ackerman. To catch a killer Eren must learn to think like one.

Two months without sun - something Eren hasn't had to deal with alone for six years. The only thing keeping him stable anymore seems to be Levi Ackerman, the name of the only human being he's had any contact with - and even then, online interaction can only help so much with someone drowning in the depths of depression, even with the happy lights.

It's his job. Being in this special operation requires apathy, a cold heart, and dead eyes, making him just the man to do it. Of course this doesn't mean he likes it. However, when he runs into three young teens in the worst possible situation a life could lead, it turns out that he isn't as heartless as he once thought he was. Modern day AU:Officer Levi, Prostitute Eren. Triggers!

Mikasa always warned Eren about the dangers of the internet and the people associated with it. Eren thinks it's a joke, though, because what harm can the people in the deepest parts of the web do? But after confronting a malicious hitman, he is led to a suspicious raven-haired man with unhealthy government connections, who gradually sucks him into a world he was shielded from.

Levi has never put much care into things, especially things that don't peak his interest. It's genuinely hard to find something that he could like, so when he meets Eren Jaeger, a nineteen year old college student who just happens to be deaf, he wonders what it is that makes the kid so interesting. Warning: Massive cuddles and feels that'll make you wish for a therapist. Rated T-M

"You know, I usually like to get to know someone a bit before chaining them up and beating them to a pulp." Levi attempts to ignore the lust driven up by Eren's position at the trial. Meanwhile, Eren gets used to sleeping in chains, and even starts to seek more from the man who put him there.

Of course the plane crash changed his life. He just didn't think it would bring him closer to a man he had always loathed; a helicopter pilot who thinks the sun shines out of his ass. Modern aviation AU. Various pairings. Rated M for future chapters.

Historical AU: Men can get quite lonely when they are off at war and it is not surprising when some fall in love. Levi was just fine. He had a lovely fiancée waiting for him back at home, he didn't need a man to warm his bed. Until he saves a cheeky, bright eyed brat. It is then that he questions where his love truly lies.

Police AU. Levi is an overworked detective for the city of Trost. The mysterious gang called 'The Titans' have been linked to several murders in the neighboring city of Shiganshina and the carnage continues as they move onto Trost.

The Wall, a gang run by none other than Grisha Yaeger. In its early days The Wall sought to protect the citizens from the corrupt Military Police. Grisha, however, became bitter and cold after the loss of his wife and soon The Wall became something more, something worse. Can Eren stop his father? Will Levi let Eren in? Eventual Riren.
