Monster Hunter Part 4 Unholy Alliance

A/N: Now I know some people may think Eren is to strong in this story he's trained himself he's almost as badass as Levi is in AOT, I hope you like this next chapter, Mikasa is still a badass she's as good as she is in AOT, if people are wondering how she doesn't act like a Vampire much well for years she's searched for Eren so now she doesn't want to lose him.

'Inner Thoughts'

Disclaimer: I do not own AOT just this story so enjoy.

Eren wakes up and sits up in bed and sigh's, did he just fuck a vampire his ex-girlfriend but still a vampire. He looks down his arm the wound is still red he sees the teeth marks and rubs his fingers across the bite marks and sighs.

He never forgot about Mikasa how could he, she was the love of his life. He can still taste her on his lips. He takes a shower and cooks himself some breakfast. Two hours later Eren walks into Titan HQ.

Armin sees him he can still see the bruises on his face. Armin walks over "Where have you been for almost 5 days buddy."

Eren raises his eyebrow "Let's go to your office."

Eren tells Armin about the trap he was lured into he doesn't tell him anything about Mikasa and the fact she saved him.

Just then Hangi comes in "I heard about your battle, I'm glad your still alive Reiner and Bertolt were good Titan's we never found out what happened to them now we do there dead though that's good."

She sits on Armin's desk "It took you a long time to heal, Are you ready to fight now."

Eren sigh's "I'm a bit bruised but I'm ready to go."

Hangi jumps off of Armin's desk and laughs "Great We have gained Intel of an enclave of Ghouls the numbers are vague but as it's an enclave I'd say a lot we already sent in Two teams only One member made it out alive"

She grins at Eren "This is just the sort of thing your good at go there and kill them if you can you sure you won't need back up look what happened the last time."

Eren smiles "Last time I thought Werewolves and Vampires also Ghouls, just ghouls this time then this will be easy, I'll be fine."

Hangi smiles "Glad your back by the way hows the hunt for that Titan Vampire killer coming along."

Eren freezes "Nothing since she managed to get away from me."

Armin looks at Eren and knows he's hiding something he's known Eren since they were 5 he knows when he's holding something back.

Hangi leaves the office and Armin closes the door "What are you keeping from me I've known you since we were 5 remember, I know when your lying or holding something important back."

Eren sigh's "Is this room ya know."

Armin raises his eyebrow then smiles but shakes his head "Come on let's go for a walk."

Eren follows him out it's late but Armin can take care of himself besides he's here he'll be fine. Eren tells Armin about The Titan Vampire killer being Mikasa and Armin freezes "You sure it's her."

Eren smiles he then tells him about the aftermath of his dance with death and how she saved him and nursed him back and that they had sex.

Armin is speechless "They remember everything and what they did before death I guess it helped you out then her being a nurse and all."

Eren smiles "Yea."

Armin then smiles then gets serious "You had sex with her though, you also let her drink from you what the hell are you insane."

Eren sigh's "I love her Armin you know I will never love anyone as I loved erm love Mikasa."

Armin nods he remembers how much they loved each other. "But she's a vampire Eren."

Eren sigh's "Yea I know she's a vampire who has a bounty on her head as she kills them and everything we do, plus a vampire I trust with my life."

He leans against a tree "She could have drained me and I would never have known, but she still loves me, maybe we can ya know maybe work with her she is a hunter of her own kind and other monsters just like us."

Armin sigh's "Eren she's a vampire nobody will trust her they will kill her."

Eren snarls "Anybody who tries I'll kill them."

Armin sigh's "I'm sorry Eren but it's doubtful she will be allowed to live."

Eren sigh's deep down he knows this "Well I better go and kill these Ghouls."

Armin sigh's "Let me know how many there are."

Eren just nods and walks away. He gets into his Ford Mustang and goes to the address Hangi gave him. It is in one of the poorest parts of Trost so an ideal place in a way.

He opens up a laptop case in the back of the car and opens up the laptop inside and grabs the infrared device and starts moving it from side to side it shows what's in there and how many he looks at the device shows him, Two thousand ghouls.

Eren smirks "Should be fun." then someone speaks from behind him it smells so bad here he couldn't smell a vampire sent but he knew that voice "What are you doing here Mikasa."

He turns around and sees her leaning against his car "Wanted to see what your doing don't tell me you plan on going in there you do know what's in there right."

Eren smirks "Yea, Two Thousand weak ass Ghouls, but that's a challenge ain't it, quantity doesn't beat quality, plus I like challenges plus its good exercise."

Mikasa smiles "Two Thousand Ghouls ain't that a bit much for one although amazing fighter a not 100% fit one."

Eren walks up to her "I'll be fine"

He walks around to the boot of his car and opens the trunk he pulls out his Katana and then pulls out some machine guns, handguns, grenade and knives.

Mikasa looks over his shoulder "Fucking hell Eren, where's the tank."

Eren smirks, "Left that in my other car."

Mikasa looks at him "Can I help."

Eren sigh's "Armin knows about you, and my boss knows I'm here it is not wise you being here."

Mikasa Smiles "Eren you went through hell a few days ago now Two thousand ghouls your good but you will need help, plus you killed one of there top generals or maybe it was a king or something."

Eren stops what he's doing and grabs her arms "I'd love nothing better than for you to help me, you know that I really do. I have to report to Armin how many there are here."

She sigh's Eren pulls out a radio "Armin this is Eren I've arrived there are Two Thousand Ghouls here will report back when I've killed them all."

Eren doesn't wait for Armin's reply he turns off the radio he'd only worry about Eren after his ordeal with the trap.

Erens pulls out several holsters and straps them to himself and some knife holsters also. He then puts guns and knives in the holsters picks up some grenades and puts them on a belt he then places over his shoulder.

Mikasa looks at Eren then grabs his hand "Let me help you."

Eren looks down at her "Mikasa, dammit you can't."

Mikasa just hugs him and pulls his face down and then kisses him "Wherever you go I'll follow even if you don't want me to, I can handle myself remember."

Eren sigh's "What weapons do you have." She pulls out Two handguns and her Machete Eren looks at her "Seriously that's all you got."

She smiles "That's all I usually need for a normal assault, not a death wish mission plus I'm a vampire so I have superior strength and agility."

Eren rolls his eyes he points down to his car "Fine, Suit up."

She smiles and then pulls out some holsters and guns and knives, While she's arming herself Eren walks to the front of the car, Ghouls usually are violent and bloodthirsty creatures who protect their own kind.

He pulls out the infrared device and checks the ghouls. He sees them all sleeping which is weird there usually awake some are but most aren't.

Mikasa walks up to Eren "Ready to go Eren, So how are you going to approach this situation, stealthily or all guns blazing and an all-out slaughter." She looks at Eren and smiles who does she thinks she's talking about she knows his reputation Eren doesn't do stealth.

Eren smiles "You know my reputation don't you."

She laughs "Yea, I do, but there are Two Thousand Ghouls maybe a different tactic is need... before she can finish Eren grabs a grenade from his belt and tosses it inside the lair.

He turns to Mikasa smirking, "Sorry you were saying something."

Mikasa laughs "Your an idiot."

Eren and Mikasa walk to the lair as they get close Ghouls come charging out there but there easily cut down.

Eren and Mikasa run into the lair slashing anything that comes near them, There's gunfire everywhere Ghouls getting blown up cut up and shot up. Mikasa is enjoying herself as is Eren although he doesn't show it on his face.

They both receive many slashes they are fighting Two thousand angry Ghouls after all. After about an hour of slashing, shooting, gutting and blowing up Ghouls there covered in blood and there breathing heavily well more Eren than Mikasa.

Eren looks at Mikasa "Good work out aye."

She looks back "Yea it was, Working with you was fun."

Eren smiles he pulls out his infrared device and points it left and right nothing there all dead. He looks at Mikasa "There all dead let us go." Mikasa nods and they walk out what waits for them though isn't good.

As they walk out Eren has his head lowered when Mikasa calls his name he looks at her and sees her Pointing he looks to where she's pointing there surrounded by Titans all pointing weapons at them both, He sees Armin who whispers "Sorry."

Eren looks around his eyes lock on Jean who smirks he then sees Hangi and knows he's in trouble but he won't back down.

Hangi then steps forward "Eren what are you doing hanging around a vampire a cute one that seems familiar but I can't picture her but a vampire non the less, care to explain yourself."

Eren sighs he's hungry and tired but he knew sooner or later they'd find out "This is Mikasa we have just killed Two Thousand Ghouls just now as you can tell."

Hangi looks at Eren she opens her mouth then closes it "She died so how is she back."

Eren sigh's "She did, she was bitten by Erwin there leader."

Hangi hears mumbling behind her and turns around "What's going on."

A titan steps out "That's the Titan killer I've seen her."

Hangi turns around "Is that true Eren."

Eren looks at her "No, she has never killed any Titan before its all lies set up by The Vampires, it's all because she hunts her own kind and also kills what we do, she has a bounty on her head just like we do."

The same Titan who spoke before speaks again "I saw her kill a titan she stabbed him in the throat."

Hangi looks at Eren and Mikasa "Is that true."

Eren doesn't know he turns around to Mikasa "Is it."

Mikasa sigh's and steps beside Eren, "The Titan was dying, he'd been bitten several times by a werewolf he begged me to kill him before he turned wouldn't you have done the same."

Hangi smiles "I guess I would."

Jean steps forward "She has to die."

Just then a bullet whizzes just below his crotch. Jean looks up to see Eren holding a smoking gun "Next time I'll take your head off and anyone who comes near Mikasa I'll kill you all."

Hangi holds up her hand "Let's not be hasty, step back Jean."

Jean reluctantly steps back. "So Eren what do you think is going to happen here your surrounded."

Eren snarls "What's going to happen is I'm going to kill anyone who comes near my girlfriend, it matters not if your friends any who attept to kill her will have to go through me and you know just who your up against"

He glances at Mikasa then back at Hangi "There are things you don't know Vampires regain their memories of there past lives, they also have all the knowledge of there previous life in Mikasa's case she was a nurse, and she saved my life I left that part out, she reset my dislocated shoulder and healed my wounds."

Hangi smiles "Really that's good information indeed I'm thankful you saved Eren, he's the best we have even if some think otherwise they know the truth."

Eren rolls his eyes "She wants to work with us she has killed her fair share of Vampires and Werewolves although not as many as me and she killed 100 Ghouls to save me after I blacked out after killing Reiner, Plus she also just helped me kill Two Thousand Ghouls in there you can see for yourself if you want."

Hangi smiles "You ask for a lot Eren, you do realize nobody will work with her kind."

Eren smiles "She's working with me so nobody has to feel threatened, you are constantly trying to get me a new teammate well I got one."

Hangi leans back into the car she's in front of. "She's a vampire doesn't she feed."

Mikasa steps forward again "I don't eat from people, I have a blood supply I use I have my own place so I won't be with anyone but Eren." She then puts her hand through Eren's.

Hangi then smiles again "You make some good points, Armin will be a mediator between you two and us, he knows you both it seems, you will also help us with vampires and everything else's locations if you have them."

She then gets serious "You will also listen to my orders if I tell you to kill anything in another country you will go." Mikasa agrees although travelling will be a problem with her being a vampire and all.

Then Jean steps forward but before he can speak Eren shouts his name "Open up your fucking mouth again and I'll gut you where you stand."

Jean steps back "Eren, are you insane she's not your girlfriend anymore she's a fucking Vampire."

Eren smirks "Thanks, for stating the obvious dumbass, I didn't know that, I will be staying with Mikasa and we will hunt together at Night then sleep together during the day which I normally do anyway."

Hangi laugh's 'They slept together wow, although I must say she's an attractive women' "So you've fucked a vampire can they even ya know feel anything."

Eren smirks "Yes we have fucked, and yes they can orgasm can't you." Mikasa punches him on the arm. Everyone starts mumbling some are giggling some are just shocked.

Eren then laugh's most people know he's Mr Emotionless so they shut up "Now you know even more about vampires they can fuck, regain memories and past skills, it's getting early we gotta go."

Hangi smiles "Off ya go then, good work you two, Armin will contact you with the new mission I think that would be easier don't you."

Jean stops forward but Hangi tells him to shut up. Eren looks at Armin and smiles, Armin knows that he doesn't blame him.

Eren then opens his car door and Mikasa slips in Eren climbs into the driver's side and starts up the car and drives away, Mikasa smiles at him "Did you have to tell them we slept together."

Eren smiles "Kinda, Yea, so where are we going, Wait do you want to drive."

Mikasa laughs "If your going to be staying with me wouldn't it be wise to know where you are staying."

Eren smiles "You could always blindfold me."

She smiles "Don't tempt me." She climbs into Eren's lap and kisses him.

Eren laughs "You may be dead Mikasa, but I'm not, you'll make me crash."

She smiles "Pull over then sit in the passenger's seat."

He looks at her raises his eyebrow but does as she asked. She quickly climbs onto him and starts kissing him. They kiss for a few minutes. Eren looks at his watch "We better get you back it is gonna be light in 20 minutes is your place close."

She just nods and climbs into the front seat and continues driving, they drive for 10 minutes then she pulls into a massive residential block but there is this massive warehouse she lets them into her place using a security system.

When she parks the car she shows Eren around her place showing him her weapons supply and blood supply. Then she pulls him into her bedroom where Eren sees the biggest bed he's ever seen. "Is this bed big enough for the both of us hey where's the coffin."

She chuckles "Oh this is my bed, you can sleep on the couch."

Eren sigh's and starts to walk to the couch but Mikasa grabs his hand "Where are you going your sleeping with me, as for the coffin remark you watch too many movies."

Eren smirks "If I must."

She smiles "Yes you must."

Eren picks her up and carries her to the bed and lays her down kissing her on the lips "Do you want to have sex I'm pretty beat up and tired."

Mikasa laughs "Me to we have all the time in the world well until you die." 'But I won't allow you to I want you with me forever I'll turn you if I have to.'

Eren then moves to the side and Mikasa lays on Eren's chest feeling his heartbeat she then leans up and kisses him on the lips and Eren wraps his arms around her and they both fall asleep in each others arms.

They both know that things will get interesting the calm before the storm maybe but whatever happens there now together, who would have thought Eren nicknamed Deathstalker and Mikasa a vampire working together, seems kind of like a romance novel or something.
