[Y/n POV]

Vergil=This.... Is curious..

Y/n=Rinne...? Rio...?

Rinne and Rio then threw me and Vergil opposite to each other.

Y/n=What the hell..?

Rinne=Enough! Both of you shouldn't be fighting each other!

Rio=Please stop, Papa! I don't want to see Papa fighting again!

Vergil=Ahh. Both of you come all this way just for that?

Rinne=You are Vergil, Right? Can you stop fighting with Y/n?

Vergil then stood up and walk toward me

Vergil=... Get out from here.. This doesn't concern you.

I then stood up as well and prepared myself to fight again but suddenly.

Rio=NOOO!!!!

Rio shouted and suddenly a red and pink aura appeared around Rio and then that aura attacked Vergil. Vergil slams against the wall after being hit by that aura.

Vergil=What form of power is this?

I burst out laughing after seeing Vergil beaten by Rio with one strike.

Y/n=Oh, brother. You ate Qliphoth for more power but you were beaten easily by my daughter ahaha...

Rinne=Y/n, stop it!

Y/n=Okay, Okay.

I then look toward Vergil.

Y/n=You were beaten by my daughter not by me so I guess our fight this time is a draw, right?

Vergil=..I won't lose next time.

Then suddenly a big quake happens

Rinne=What happened?

Y/n=..! The underworld is taking over. We need to cut this tree fast.

Vergil=That's right. If those roots continue to spread through the town, It'll just interfere with our business.

Y/n=Now, that's the smartest thing I've ever heard from you.

Y/n=... Better hurry up. We still have to clean up this garbage.

Vergil=Evidently

I then started walking with Vergil.

Rinne=Wait, where are you going?

Vergil=We need to sever the Qliphoth roots from the underworld itself.

Rinne=Wait, Is there another way?

Y/n=No. This is the only way.

Rinne=But Y/n.

Y/n=Don't worry Rinne. My pop is with me this time, I'll be fine.

Rinne=Promise me you will return safely.

Y/n=Yes, I promise.

I then continue walking but..

Rio=Papa! Please don't go!!

Rio held my hand so tightly.

I then knelt down and rubbed Rio's head.

Y/n=Rio, Papa promised Papa would come back to you and Mama

Vergil=Make haste, Y/n.

Y/n=Okay!

Y/n=Listen, Rio. Papa has to go now. Please go back to the Fraxinux with Mama.

Rio=Papa, Are you really promised to come back?

Y/n=Yes. Papa promise.

I then kissed Rio's forehead. After that, I stood up again and walk toward Vergil.

a bright yellow light then appears around Rio and Rinne.

Rinne=Y/n! don't break your promise to us!

Y/n=Okay!

They then disappear.

Y/n=Alright... Let's go Vergil!

I and Vergil transformed into our Demon form and then we fly toward the portal.

[At the Fraxinux]

[Rinne POV]

Me and Rio have now returned to Fraxinux.

Shido=Rinne, where's Y/n?

Rinne=... Y/n went to the "Underworld" with his brother...

Now everyone was shocked.

Kotori=Why did he do that?

Rinne=He said he had to cut Qliphoth roots from the Underworld itself with his brother.

Shido=Will he comes back?

Rinne=He promised me and Rio, he would come back... I'm sure! He would return...!

[At the Underworld]

[Y/n POV]

Y/n=Wow, this thing got really big...

Y/n=So, we have to cut this thing down?

Vergil=That's right.

Y/n=Well. You tryin' to compensate for something?

Vergil=Yes. Your incompetence.

Y/n=... By the way, I think you should catch up with me and get married.

Vergil=There's no need for me to "catch up".

Y/n=Well, with an attitude like that, you will never have a kid.

Vergil then pointed Yamato to me.

Vergil=That's enough. I don't want to hear it.

Y/n=O...kay.

Vergil=Now, don't get in my way.

I then summoned my sword.

Y/n=Took the words right out of my mouth...!

Vergil=Hmph..!

Y/n/Vergil=Haaaaaaaaa!!!!!

*Two hours later*

[At the Fraxinux]

2 hours have passed after Y/n left.

Rio=Mama. Will Papa really return back to us?

Rinne=I'm sure He will come back...

Shiizaki=Commander! Look at this!

Kotori=What?

A monitor then appears in front of us.

Shiizaki=The Qliphoth tree and its roots are starting to crumble! It's the same in every country! The demons also died one by one!

Kotori=They did it!

Everyone in this room seemed very happy after all of those roots were destroyed.

But I'm still worried about Y/n.

Rinne=Y/n please return back to us...

[Meanwhile at the Underworld]

[Y/n POV]

After two hours non-stop, Vergil and I managed to cut down the Qliphoth tree.

Y/n=Fuuuu. Cutting this garbage is sure is hard work.

Vergil=Well, for the first time, I agree with you.

Suddenly a big quake happens.

Y/n=What now?

Vergil=...! The portal to the human world is closing, Y/n. Because the Qliphoth has been cut down.

Then at the same time, thousands of demons surrounded us.

Y/n=What are we gonna do now?

Vergil then gave Yamato to me.

Y/n=What are you...

Vergil=Give that to your daughter. It stays in the family.

Vergil then transformed into his Demon form and summoned his spectral sword.

Y/n=But Vergil, I can't-

Vergil=

Y/n=But...

Vergil=

Vergil=...

Vergil then kills half of the thousands of demons that surround us to clear my path.

Vergil=

Y/n=Cihh... I don't have any choice...

I then transformed into my Demon form and then I flew towards the portal.

I made it through the portal and returned to the human world. After that, I sealed the portal with Yamato.

Y/n=

[At the Fraxinux]

[Rinne POV]

Right now, everyone including Rio and I is waiting for Y/n's arrival.

Mana=Do you guys think he will come back?

Kaguya=Yes. I'm sure!! He is our rival! the Legendary Yamaii sisters !!! He will definitely come back!!!!

Suddenly the space in front of us got distorted and a blue portal appears.

Mana=What is this?

Then someone wearing a red coat and had a white hair came out of the portal while holding a Katana.

That person is...

Everyone=Y/n!

Y/n=Hey, everyone. I'm back...

I then ran towards Y/n and hugged him tightly.

Rinne=Y/n! I know ... I know you will come back to us!

Y/n=Y-Yeah..

Y/n seems to be sad about something... Wait, where's his brother?

Rinne=Y/n, where's your brother?

After I said that, I saw tears slowly come out of his eyes.

Rinne=Y/n... Are you crying..?

*Y/n POV*

Tears slowly came out of my eyes after Rinne asked me about Vergil.

Rinne=Y/n... Are you crying..?

Y/n=... My brother... He... He sacrificed himself so that I could get out of the Demon world ... He saved me ...

Rinne=Y/n...

Y/n=I... I lost my family again... I don't have a family again ... He is my only family and now I lost him again ...

Rinne then wiped my tears.

Rinne=Y/n. You still have me, Rio, and everyone else here. You're not alone, so don't be sad.

Y/n=Rinne...

I then hugged Rinne tightly and I crying on her shoulder.

Y/n=Thank you ... Thank you, Rinne ... you are always by my side when I need you ...

Rinne=It's alright, Y/n... It's alright. I will always be beside you. No matter what happens I will always be beside you and I will never leave you alone...

Y/n=Rinne...

[Seven months later]

[Y/n Residence]

Seven months had passed after my incident with Urizen. And since that time Demons never appeared again.

Everything went back to normal. Tengu city is now recovering from the damage caused seven months ago..

And now, I reopened my cafe after a long renovation. Thanks to Ratatoskr I now get money to start my business again.

Rinne=Hey, Y/n. don't be too loud. Riko is sleeping now.

Y/n=I'm sorry, Rinne.

Oh. and yesterday Rinne just gave birth to our baby. We named our baby "Riko Sonogami" just like what we promised a few months ago.

By the way, I gave Yamato to Rinne shortly after the incident with the Qliphoth Tree. I told Rinne to keep Yamato until the time was right to give it to Rio.

And about Vergil, I think he is still in the underworld fighting those demons to this day. Well, I'm sure he's all right now. Since he ate the Qliphoth fruit, he should have the same strength as a Demon King.

Rio=So now Rio has become Onee-chan right, Mama?

Rinne=Yes that's right Rio. You now have a little sister and that means you have become Onee-chan.

Rio=Yaayy!!!

Rinne=Rio, please lower your voice, Riko-chan is sleeping right now.

Rio=Hai, Mama...

Rio then whispered in a low voice to Riko.

Rio=Hey, Riko. When you grow up, let's play together with Onee-chan...

Rio=Hehe... Riko is very cute just like Mama!

Rinne=Hahaha... Thank you, Rio.

From this day forth, there are things waiting for me and Rinne that I can't possibly imagine, and I ready for that, we will face the future together.

Rinne=..I'm so glad Riko came into our lives...

Y/n=Yes. Riko brings happiness to our family...

Rinne=Yeah. You are right...

No matter what obstacles life threw at us we learned to heal. I know it to be true. Of course, you can't let life pass you by sometimes, you need to confront your Demons.

Rio=Papa, Mama! thank you for bringing Riko to our family. I really love Papa and Mama!! Papa and Mama will always be with Rio and Riko forever!!

Y/n=Right. Papa and Mama will always be with Rio and Riko.

Rio=Thank you Papa! Mama! I'm very happy!!

... The legend of Sparda and his three twin sons is now over. The dark fate of the Sparda family is now reached the end.

Now, a new era will begin. An era that could take up the rest of our lives, protecting what's dear to us....

Rinne=.. In my life... I think I'm the happiest.

Rinne=Y/n... Let's be together forever..

Y/n=Yeah. Let's be always together... Forever...
