Izuku's P.O.V

I was called by Oyakata-sama, he said he has a mission for me... After walking towards Oyakata-sama's place, I saw Rengoku kneeling towards Oyakata-sama.

Oyakata: Kyojiro, You know your mission wait for Izuku and finish your mission and return alive...

Kyojiro: Of course, Oyakata-sama, I still have many duties as a Pillar...

Izuku*bowing*: Oyakata-sama, You have called me?

Oyakata: Yes, I want you and Kyojiro to find a demon that is said to be attacking passengers on a train...

Izuku: Is that all, Oyakata-sama?

Oyakata: Yes, and please bring Tanjiro and his friends with you...

Izuku: I'll send my messenger to inform them.

Oyakata: okay, Izuku.

When me and Kyojiro left, we saw Shinobu.

Izuku: Oh, Shinobu... What are you doing here?

Shinobu: Ah, Darling, I'm going to Oyakata-sama, to inform him about the condition of the slayers that participated in Mt. Natagumo.

Izuku: Oh! Well then, I'll see you in a bit...

Shinobu: Ah! Darling wait!

Izuku:Why?

Shinobu: You and Nezuko did it, didn't you.

Izuku: Did the what?

Shinobu: The Deed.

Izuku*blushing*: Um... I mean, yes, I mean maybe... How did you know?

Shinobu: She's pregnant...

Izuku: • • • What?

Shinobu: Like I said she's preg-

I quickly ran at high speed to the butterfly mansion, After I arrived I saw Nezuko coming out from the bathroom, Tanjiro along with Eri and Kota with a really, REALLY happy face, Zenitsu with a jealous face... And Inosuke with a confused look, Mitsuri and Kanao looking at me, like 'us too.'

Izuku: NEZUKO!!!

Nezuko: Geez, Izuku calm down... I'm fine.

Izuku: Are you sure?

Nezuko:Yeah.

I felt a hand in my shoulder and I saw Tanjiro with flowers all over him...

Tanjiro: Izuku, You really made me an Uncle... But why did you two do it?

Izuku: We were in a cave at night... It was raining... We were soaking wet, I put up a fire, we took of our clothes, she felt cold so I hugged her, and we got caught up with the heat of the moment, and you know what happen from there.

Eri: Kota! We have a younger siblings!

Kota: Yeah! Dad can we help mom in taking care of her and our sibling?

Izuku: Sure...

Nezuko: So, Izu what will you be doing today?

Izuku: Mission... Tanjiro, Zenitsu, Inosuke, come with me, we'll be doing a mission with Rengoku.

Tanjiro: Eh... What about Nezuko?

Izuku: Even though I want to be with her We still have a mission, don't worry will return as fast as possible.

Tanjiro: Fine.

Izuku: See you later Nezuko, Girls! And Tell Shinobu, Have to talk to her!

Girls: Bye! We'll tell her!

After half a day of walking to the station, and bought tickets we finally got inside the train and saw Rengoku, eating...

Rengoku: Delicious! Delicious

Tanjiro: Flame Pillar, I'm Tanjiro Kamado!

Rengoku: Delicious!

Tanjiro: Okay...

Izuku: Rengoku can I have some?

Rengoku: Sure!

Both: Delicious!

Zenitsu: They're both broke...

We heard screaming from the back cart.

Izuku: Rengoku, a Demon at the back.

Rengoku: I know.

He stood up and draw his sword, the demon showed up.

Rengoku:

Rengoku: I guess it's done!

Izuku: Nope, There's still one... On the roof... I'll get it.

I vanished and appeared on the roof and saw the Upper rank Three, Akaza.

Akaza: So you're the rumored Slayer who killed all the lower rank?

Izuku: No, Just some of them.

Akaza: Sorry but you need to die.

Izuku: Sorry too but I can't.

We clashed, dodging each others attack. He tried to hit me in the chest but I blocked it with my sword.

Akaza: Your good but can you save all of them?

Izuku: What do you mean?

Akaza: This!

He destroyed the rails and the train stumbled and got off tracks.

Izuku: You just made it easier...

I advance to him and after I got closer.

Izuku:

He dodge my attack, he looked at me smiling.

Akaza: Your stupid breathing wont hurt me!

Izuku: Who said anything about hurting you, let me tell you something about my third form... Yes you'll fall asleep if you got hit. But the thorns also produce sleeping gas... And you inhaled it...

Akaza: Like I said it won-'why did my body stopped, why do I feel sleepy...'

Izuku:

My sword formed an Sycthe, I cut his head off. I lay down on the ground to take a breather... I heard someone calling my name, I looked up and saw Tanjiro running with the other three walking behind him.

Izuku: Yo! Tanjiro, I know I said we'll comeback after, we're done here... But let me take a breather...

Tanjiro: Sure, we just finished up bringing the passengers to safety...

After a while, We returned home and we went to Oyakata-sama's place to report on our mission.

Oyakata: It seems that you returned and your mission is a success?

Rengoku: Hai, Master, And I must say something else...

Oyakata: What is it?

Rengoku: I want to resign as a Slayer, all the years, I spent here are important but, I want to live a normal life from now on... I will still help in anyway that I can...

Oyakata: I understand... It's a great loss to us but I must respect you decisions...

Rengoku: Thank you Oyakata-Sama... And Tanjiro I want you to have my sword... You've proven to me that you have strong will when you acted fast on the accident.

Tanjiro: Are you sure? Rengoku-san?

Rengoku: Yep.

Izuku: Oyakata-sama, I'll take my leave, I need to look after my girlfriend and talk to Shinobu.

Oyakata: Okay, Izuku.

I walked to the butterfly mansion, when I arrived I was tackled by the girls.

Izuku: Nezuko, How are you?

Nezuko: I'm good, Where are the others?

Izuku: They might be still walking... Shinobu... I want to talk to you, about your sister...

Shinobu: What about her?

Izuku: I'll revive her along with someone for Tanjiro...

Nezuko: Who?

Izuku: You'll see...
