Y/n in his Titan from was now facing the Bone Titan that killed many Survey Corps. It also killed the one's he called family we he first joined the Surgery corps. And now, he's going to kill this Titan in so many ways until the one controlling it comes out.
Y/n: You killed my family and you're going to pay.
The Bone Titan did the first strike as it went for a slash but Y/n dodged it easily. The Titan then did a barrage of slashes but Y/n just dodged without effort. As the Bone Titan went for a final downward slash, Y/n sidestepped and punched the Bone Titan with his gauntlet covered fist to Bone Titans face making it skid back. Steam came out of it's face as it started to heal from the impact of Y/n's fist.
Y/n did a boxing stance and rushed forward. The Bone Titan went for a slash but he ducked and delivered a massive right hook. He didn't let it to counter so he rushed again and bombarded it with jab, hooks and uppercuts. He could tell that the Titan is not really good with close combat as he keep on dodging and countering with hard punch.
Y/n: You are dead to me.
Y/n did a massive haymaker but the Bone Titan jumped out of the way as Y/n hit a tree destroying it. The Bone Titan then pushed him away a few feet. He looked at the Bone Titan and saw that it was steaming from all around it's body. It then kneeled down tired and injured from the fight.
Y/n stood straight and made his gauntlets disappeared. He then opened both his hands and used his Warhammer ability to make a hammer ready to slam the Titan to a pulp. He stopped in front and stared at it with a death glare. His lower face plate opened revealing it's sharp teeth as he raised his hammer up.
Y/n: Die!!!
With a mighty roar, he slammed his hammer down but the red haired female Titan appeared and grabbed the Bone Titan out of the hammer's way. Y/n turned to the red haired Titan and saw that she was also injured because of the fight with Annie. He was about to raise his hammer again but someone called him making him turn around.
Mikasa: Y/n!
Y/n: Mikasa?
Mikasa: Let's go! Captain Levi said to retreat.
He nod and turned towards the two Titan shifters to see the bodies started to evaporate and their names are open.
Mikasa: Don't worry, we'll get them.
Y/n: Right, hop on.
Mikasa then landed on his shoulder as he sprinted away towards where the others are to regroup. Up above the tree, we see two individual leaning on the trunk of the tree as they were exhausted. It was a girl and a boy as the girl was looking around to see if they were followed.
Girl: Coast is clear.
Boy: They we're joking about him, I can't even land a hit.
Girl: Are you sure we're still doing this? What if they find out?
Boy: They won't, let's just get back so that they won't suspect us.
Girl: R-Right, I just want this to stop. Are friends are dead because of us.
Boy: I don't regret doing it. It's our job anyways. Let's go.
They used their ODM gear and zipped through the forest until they found their horse and rode back to the others.
Time Skip
Y/n was now in a carrage with Petra who has bandage on her head and Armin sitting across him with a bandage on his head from the injury he got when the Bone Titan attack his side of the flank. Eren was also in the same carrage as him and also unconscious. Annie and Mikasa on their horse as they are now going back to base as the mission had failed.
They arrived back at base as Y/n saw Oluo, Eld and Gunther's body are being put inside. Eren and Petra are brought to the infirmary to check on their injuries. Hours later, Petra finally woke up and saw Y/n sleeping on her bed while holding her hand. She rub his head making him stir and woke up.
Petra: Hey, are you-
She was cut off as Y/n instantly embraced her while tearing up a little.
Y/n: You're okay, glad nothing bad happened to you.
Petra: Hey it's okay, I'm okay.
They separate the hug as Petra wiped her tears away.
Petra: Thank you for saving me Y/n.
Y/n: B-But I couldn't save the others. I didn't transform in time and-
Petra: What matters is that you're safe and I'm still here to take care of you.
Y/n calmed down and sat next to her on the bed.
Petra: How did the mission go?
Y/n: The mission failed and when Eren wakes up, he'll be sent away.
Petra: Where's everyone?
Y/n: Taking a rest.
Petra: You should too.
Y/n: I'm fine, I won't leave you here.
They then heard a knock on the door as it opened revealing Shiva.
Shiva: I'm not interrupting something am I?
Y/n: No mom, we are just talking. What brings you here?
Shiva: Just came here to check up in you and Petra. You've been here since she was taken in and didn't eat anything so I brought you guys food.
Petra: Thank you Mrs. L/n.
Shiva: Just call me Shiva sweetie.
She put the food on the bed as Y/n and Petra started to eat. Shiva then stared at how close the two are.
Shiva: You guys are really close huh?
Y/n: Yup, Petra is like my big sister here. She was the one who insisted to take care of me when I first met them.
Shiva: Well thank you do much for taking care of him Petra, I really appreciate it.
Petra: It's no worries Shiva, Y/n was so cute when we first met him 5 years ago. The fact that his titan form just spoke when we approached him.
Y/n: I still remember the shock faces of everyone.
Shiva: Oh Y/n, Annie and Mikasa are very worried about you. You should go see them.
Y/n: Sure, see you when come back sis.
Petra: Okay. I'll be having a talk with your mother.
Y/n: By the way Mom, where's the baby?
Shiva: Her name is Sophie and she's with Sasha.
Y/n: Okay then, see you guys later.
Y/n walked out of the room and searched for Annie and Mikasa. He walked around until he saw them sitting on a wagon.
Y/n: Hey you two.
They looked up and instantly ran towards him and gave him a hug. He hugged back and kissed their heads.
Annie: We were so worried about you.
Mikasa: When we went to Petra's room, you were asleep. Have you eaten yet?
Y/n: I already ate and thank mom for that. How about you guys.
They shook their heads cutely.
Y/n: Come on, I'll accompany you two.
They went inside the mess hall and saw everyone eating food. Mikasa and Annie walked towards where the food are and grabbed something to eat. Y/n sat where Sasha and the others are and saw her playing with the baby.
Sasha: Who's a good girl? You are.
Sophie: *giggle*
Y/n: I see you're enjoying yourself Sasha.
Sasha: Of course sir.
Y/n: Drop the formalities, call me Y/n when we're not in a mission.
Sasha: Sure.
Then the baby turn towards Y/n and held her arms out signaling him that she wants to be carried. Y/n grabbed the baby from Sasha and carried her in his arms earning a happy giggle from the baby.
Sasha: I guess she likes you.
Y/n: I guess.
Connie: Woah! Y/n's great with kids.
Armin: You'll be a great father in the future.
Y/n: Come on guys stop that.
Ymir: I can see why Mikasa likes you so much.
Christa: Agreed.
Jean: Wait! You and Mikasa are a thing?
Connie: You didn't know? I mean they been so close since last week.
Jean: What about Annie?
Annie: What about it?
Annie and Mikasa then sat on both Y/n's side.
Jean: Like how Y/n is cheating on you!
Annie: What are you talking about? We're sharing him?
Sasha: Sharing?
Mikasa: We agreed that two of us will love Y/n equally and he does the same.
Connie: Man Y/n, you got to show me some things to get ladies.
Y/n: Maybe next time when we find those two Titan shifters.
Armin: I heard it's in our ranks. Who do you guys think it is?
Y/n: I don't know about you guys but I have a lead on who those two are.
Mikasa: How?
Y/n: They aren't good in close combat and I think they use their ODM gears more train martial arts.
Annie: I also see that when I fought that red haired titan.
Y/n: And when we checked everyone's ODM gear to find who killed Sonny and Bean but let's wait for the right time. I going to tell Captain Levi later.
Mikasa and Annie then ate their food as everyone started converse with each other while Y/n was busy playing the baby as it started to laugh in a cute way.
Annie: Someone's enjoying.
Y/n: I can't help it, she's so cute.
Annie: You're really good with babies, how about we make one for ourselves~
Everyone stopped what they're doing and stared at Annie with wide eyes. Mikasa was just minding her own business and keep on eating her bread.
Y/n: I'll think about.
They got even more shock and the girls were blushing.
Annie: Oh~ so what do you say Mikasa? You in~
Mikasa: Making a baby with Y/n? Sure, I don't mind.
Christa: A-Are you guys being serious?
Annie: Hahaha, we're just teasing you guys. We're still not ready for that kind of stuff.
Mikasa: I'm already fine with having baby Sophie here.
Sasha: She has a name?
Y/n: Yup, mom named her Sophie. Isn't that right Sophie?
Sophie: *baby laugh*
Time Skip
Y/n, Annie, Eren, Levi and Petra who is feeling better are on a table as Y/n explained to them who the two Titan shifters are. They were waiting for Commander Erwin and the others.
Eren: No way, those two?
Petra: Now you think about it, they are always distant from the others and sometimes disappear.
Levi: They also disappeared when we were in the forest and came back when Y/n and Mikasa arrived. They said they got lost from everyone when they entered the forest. And that red haired Titan also caught us off guard when it came out nowhere and was about to grab Mikasa but I pushed her away and I sprain my foot.
Y/n: What about you sis?
Petra: Just a little concussion. I guess me and Captain Levi are out commission for now.
Annie: I still don't know what that red haired titan's ability though.
Y/n: All that I know about the Titan me and Eren fought that it can make the bones all over it's body use as a weapon.
Eren: That why he cut my head off easily.
Then the door opened revealing Erwin, Hange, Armin, Mikasa and Jean going in.
Erwin: I heard from Armin that you found out about the two spies.
Y/n: Yes and I devised a plan in order to catch them.
Erwin: Okay then, let's hear it.
Y/n then started to explain to everyone his plan on how to capture the two spies. Erwin agreed and said that they'll start tomorrow so he told everyone to prepare for the plan. They nod and went towards their rooms to rest. Y/n was on his bed staring at his ceiling as let out a sigh.
Y/n: Eld, Oluo, Gunther. Sorry for letting you guys down
He then heard a knock on his door.
Y/n: Come in.
The door opened to reveal Mikasa as she went in and closed the door.
Y/n: Mikasa? What are you doing here?
Mikasa: Mind if I sleep with you?
Y/n: Well sure, I'm about to sleep anyways.
Mikasa then got on his bed and laid down beside him as they faced each other. Y/n gave her a peck on the lips and she cuddled close to him until he felt someone hugged him from behind.
Y/n: Someone's jealous.
Annie: I'm not gonna miss this out.
Y/n: You could have just asked you know.
Annie: Where's the fun in that.
Y/n: Okay okay. Goodnight girls.
Mikasa: Goodnight Y/n.
Annie: Night Y/n.
