It was the middle of the night and we find Y/n and Leone sneaking their way within a large building where a group of crimlords are in as the two are within the basement like room as the two approaches one of the ceiling doors and then open only to see purple gas as they see countless of girls gathering around and touching each other and moaning.

Y/n: What sort of gas is this?

Leone: A gas that makes women turned on. They kidnapped women or buy them at black markets so they can have fun with them.

Y/n: Disgusting.

Then two brothers enter the room to over see the women. One of them is seen going through a lot of pain and wanted to be free. But one of them kicked her before she can touch his shoes.

Y/n is disgusted by this but he noticed Leone looking pissed off which is something he never see her get this mad.

Y/n: Tell take care the guards while you'll deal with our target.

Leone nodes as Y/n leaps onto thr room and sneak his way to the door. He lend his back next to the door and then knock at the door. Moments later a guard opens ans step inside only to be pulled and get stabbed in the knife.

He leaves the room and quickly and quietly take out the guards across the hallways as he stab them with his hidden blade. We see him finishing off one a door ahead of him opens and the guard turns to see him.

Immediately he draws out his knife and throws it and the knife impaled the guard in the forehead and he collapses onto thr ground. He continues killing the guards when suddenly he hears a massive noise and screams but luckily he took down the last guard and clear out the building.

We soon see Y/n on top of the roof and looking at the veiw when Leone approaches him with blood still on her claws as she said while stretching her arma.

Leone: That sure feels great. I needed that.

Y/n: I bet you do. You look mad earlier. I can tell you have a dark past as well?

Leone: Yeah something like that.

Y/n:........

Leone: Hey I sometimes wonder?

Y/n: What?

Leone: Do you ever wonder what will you do after all of this is over? I mean.....you never know what it feels like living in a normal life. Ever wonder that you wanted to live a normal life?

Y/n:......I'm not sure. Being an assassin is all I know. I know you and the rest have terrible lives but at least you all had normal lives unlike me. I never even know my parents. I know it may sound annoying but.....it's just these thoughts that always comes back you know. I sometimes wonder what it feels to have one.

Leone: Yeah.

The two stared at the night sky for a moment and then Leone turn to Y/n and then she lick his ear which made him step back while blushing.

Leone: (giggle) No point escaping, I just mark my territory so your mine.

Y/n: Your taking this "lion" thing a bit too seriously.

Leone: (shrugged) It's how I roll. Plus you love it do you?

Y/n: Let's stay focus on something else. What about Mine and Sheele.

Leone: Think i saw them at the park.

For some odd reason he had a odd feeling something bad might happen.

Y/n: I'll check on them.

Leone: (smirk) Cool. I'll meet you back in base.

Y/n nodes and he heads off. He enters the park and make his way where Mine ans Sheele is at however he had a feeling that someone is watching him. He feels like eyes watching at him all around him.

Soon he exit out of the trees and enter a wild open space where Mine qns Sheele where there as they turn and see him.

Sheele: (smile) Oh hello Y/n.

Mine: What are you doing here?

Y/n: Here to check on you two. Everything okay?

Mine: Yeah got our target and we were just about to leave.

Y/n: Okay.

He looks back into the forest and feels like someone is watching them. The two of them noticed and before they can ask him they heard.

???: Been waiting for this for a long time.

They look over to see what seems like a female Knight with a dog as the trio look at her.

Mine: Whose she?

Sheele: No clue but her armor. She's from Jargers.

Y/n: What business have you come here for?

She then begins to laugh a bit which confused the trio as she begins to say.

Seryu: (smile) My name is Seryu and this is my friend Hekatonkheries but I call him Koro.

Sheele: (smile) Aaaww her doggie is cute.

Y/n: Don't lose focus. Something tells me she's bad news.

Seryu: (giggle) Indeed. You Nigh Raids killed my father so I come here fore revenge. Koro.....GET THEM!

Suddenly Koro suddenly transform into a gaint beast which surprised the trio as Koro roared at them while they draw out their weapons.

Mine: So guess we have to deal with her.

Y/n: Indeed. However this will be quick. Sheele.

Sheele: Right!

Both Y/n and Sheele rushes towards Koro while Koro rasied his fist and then slammed his fist onto thr ground. This created a blast that sent Sheele and Y/n flying but Y/n fired a grapple at Koro's arm and he make his way towards Koro and then slice off Koro's arm off.

He turn to see Koro cut up arm but suddenly it grew back which shocked Y/n. Then quickly he dodges Seryu's swing and leaps back and land on his feet.

Seryu: (smirk) I don't remember you but if your apart of the Night Raid then your dead.

Y/n: Be warned I will kill you before you even notice.

Seryu: (smirk) Like to see you try!!!!

She charges towards him and swing her blade at him but he blocks it and the two begin to dual while Sheele is having a hard time taking on Koro. Mine fire her Pumpkin at Koro but his wounds immediately heal.

Koro goes for a punch which Sheele try to block but the impact sent her flying as Y/h sees this and he immediately kicked Seryu back and he rushes into the forest after her.

He soon find her laying on the ground as Y/n rush up to her and he help her up.

Y/n: You okay?

Sheele: Yeah. Thank you.

Suddenly Seryu appear behind the but Y/n turns and block his sword. He pushes Seryu back and soon she was against a tree as the two enter a blade lock and then he tossed her aside and Sheele tries to land a strike but she missed as Seryu moves back. However this leaves her open as Y/n rushed over and then slice off both of her arms.

Her arms dropped to the ground and soon she collapses onto her knees while he aims his blade at her neck.

Y/n: You must be a fool to come all this way for revenge.

Seryu: (smirk) It will be worth it though.

He just glare at her when the two heard Mines scream. They look at each other and they immediately rush to her aid as they leave Seryu be.

Soon they arrived to see Mine being grabbed by Koro and Koro was about to be crushed when Sheele rushed over and cut off Koro arm and Mine falls to the ground while Y/n throws some explosions and made Koro stumbling backwards.

Mine: Thanks for that Sheele.

Sheele: (smile) Anytime.

Suddenly there was gun fire and Sheele gets shot in the shoulder. Mine is stunned by this while Y/h turns around and see Sheele about to fall. He turn to see Seryu revealing to having a barrel in her mouth this whole time.

Suddenly Koro charges towards Sheele and open his mouth as time slows down. Y/n sees this happening so with a serious face he rushes after Koro, leap up and run up to Koro's back and then leaps over Koro as he fire a grabble to wrapped around Sheele and he pulled her away as Koro missed.

Time turns to normal as Sheele falls to the ground as Y/n land on his feet. He rush over to Sheele to see her injured and turn to Mine and seeing her injured as well. He then heard something and turn to see that Seryu had back up. He look at the two injured girls and then tells Mine.

Y/n: Mine! Take Sheele and get out of here!

Mine: (shocked) What?! What about you!?

Y/n: I'll hold them off. Give you two time to escape.

Mine: Don't be a idiot! Your coming with us!

Y/n: We can't outrun them with you two being injured. Someone has to stay behind and hold them off.

Mine: NO! I WON'T DO IT! THERE HAS TO BE ANOTHER WAY!?

Y/n:.....Mine please.......do this for me.

Mine is shocked as Y/n draws out his sword as warriors from Jaegers arrived and draw out theie swords. Mine was now in tears and with no choice she takes Sheele and they escape into the forest. Y/n sees this and knows this is now he make his sacrifice.

He ready his sword and then he charges towards them and get into a battle while Mine begins to cry as she have to abandon Y/n to his death as we can hear some screams and sword clashes but soon it falls silent as a unknown blade falls and hits the ground.

(Later)

A rain came as we see all the Night Raid gather outside where Mine and the injured Sheele came and Mine told them all what happened and what happened to Y/n. All fall silent and couldn't believe that Y/n would sacrifice his life for Mine and Sheele and even saving Sheele's life.

Tatsumi was hit the most as he started to get along with Y/n but now he's gone and he forms a fist of rage.

Tatsumi: Then what the hell are we standing around for?

They all turn to Tatsumi and seeing his rage boiling up so Najenda tells him.

Najenda: I know what you are thinking and that will be suicide. Y/n give his life to save Mine ans Sheele. Even if he is alive, it most likely they capture him and torture him to death.

Tatsumi: (angry) SO WHAT?! ARE WE JUST HAVE TO ACCEPT THAT HIS DEAD! HE'S ONE OF US! WE CAN'T JUST LET SOMEONE DIE! I CAN'T LOSE ANOTHER FRIEND!

Suddenly Bulat punches Tatsumi in the face which cost him to drop onto the wet grass as Bulat barked at him.

Bulat: THAT'S ENOUGH TATSUMI! He give his life just to save Mine and Sheele! He give up his whole life just to save them! If weren't for him, they would never made it back here alive!

Tatsumi was about to argue but falls silent and looks down. Bulat then let's out a sigh and then tells him.

Bulat: If lucky he could come back but either way it be risky to find him. They might use him as bait just to lower us out of hiding.

Najenda: That is true. For now.....we just continue and hopefully he comes back.

All didn't want to continue but they all knew what they sigh up for and maybe one day Y/n might come back. Mine couldn't believe that she was a fool for abandoning him. Disbite her being rude and a jerk he saved both her and Sheele's life.

Mine: (thought) Y/n.....Thank you.......I should have apologies for everything I said to you. I promise.......I promise you that if I find Seryu and that stupid dog.......I'll kill them both.

To be continued............................................
