-AUTHOR's POV-

.

.
.
Meanwhile, somewhere under the station, there, we see someone who survived from one of Jogo's attacks from a while ago after Dagon's death, it was Nanami, he was walking down to the station, half of his body burned to crisp, and yet he seems tired already...as he knew his time was up, or to say he's finally about to take his vacation.
.
.
He began to daydream about where he would take his vacation. He pictures himself in a lonely, quiet and calm beach. He can feel the fresh air around him, the beautiful view of the ocean too, walking down and hearing seagulls.
.
.
In the real world, Nanami arrive to an area filled with transfigured cursed spirits, and at the same time to think about where he would take his vacation on the other side.

Nanami: Malaysia...Yeah, that sounds like a nice place to be there. It's nice and peaceful there. I'll build a hut there close to the beach. Finally have quality time to read the books I've never read...I'll go through page by page, and take all the time I lost....but...right now, I have to go find Fushiguro...but, what about Maki?? And Naobito?? What happen to them? ....Shit, Im really tired, exhausted even...yeah, exhausted...I've done enough, have I?

with that said, Nanami charges to the transfigured cursed spirits and started killing them one by one, but at the same rime he's tired...all he could think of is Malaysia...think about the calm and beautiful beach, and feel the fresh air and feeling free from working so hard after all the risk he has put, and has never regret at all. He's down everything he can to protect the ones he cared for and the ones he's close, and now...he will finish one last job so he can clock out...and call it a day.
.
.
.
As he now finished taking care of the transfigured spirits, and none to be left...he stood still...and felt someone touching him from his back...

Nanami: So...you're here.

Mahito: ...I've been here, this whole time.

It was Mahito, and since he touched Nanami...Nanami can't do nothing about it but accept his fate already, and he will.

Mahito: Shall we chat for a bit? You and I do go way back after all.

Nanami: ....

Nanami stood quiet...and began to think of Haibara, his old classmate when he was once a student of Jujutsu...

Nanami Mind: Haibara...what was I even hoping to accomplish to the end? I ran away, and yet I came back cause if a vague idea for a job worth doing...I can't...that's wrong. I can't, Haibara. I can't see that. I'll become a curse upon him.

Nanami began to imagine Haibara, right informe of him, smiling at him, how he always love to smile...almost like he can refer Haibara to Itadori, how they always like to be so joyful and excited and pure hearted.
.
.
Suddenly, Mahito heard footstep behind, as if someone was running down here...he turns and to spot Itadori...

Mahito: Oh. Just in time.

Itadori then notices Nanami there, in such bad condition...

Itadori: Nanami...

Nanami sees Haibara, pointing over to Yuji...telling him to look at him...but he doesn't...then, he began to have a little flashback, the time when he first met (YN).

-FLASHBACK-

Back then, before the Shibuya incident, (YN) was gonna make a trip to Africa to go see and meet Yuta for training, but not to go alone, to go with Nanami as Gojo introduce to him...

Gojo: Hey Nanami! This here is my student, (YN) (LN), he's a special grade too.

Nanami: ...

(YN): Um...nice to meet you, Mr.Nanami, sir.

Nanami: Pleasure, and just call me "Nanami."

(YN): Okay.

Gojo: Anyways, I have a favor. He's gonna head over to Africa to meet one of my other students, Yuta Okkotsu. So I want you to join with him.

Nanami: What? But-

Gojo: Yea? Great! The tickets are booked in and only have an hour left before your plane leaves. Bye!

Nanami: Hey wait!

Gojo leaves, and leaving (YN) with Nanami in his office...

Nanami: ...Like I don't even have a choice I guess.

(YN): So...Nice office. Like to be formal??

Nanami: Yes. Okay, let's make this clear. You won't find me like Gojo, not that type of person to be kind and sweet with first meeting with people. So just-

(YN): Woah! You have lot of books, cool!

Nanami: ....Uhh, why yes, I do.

(YN): Oh man! You got some books I wanna read! Like this one here, I mean....if you can let me borrow it? I promise to keep it safe and not let nothing bad happen to it.

Nanami began to have second thoughts on (YN)...to think he's almost like Itadori...

Nanami: ...Go ahead. As of matter of fact, you can keep it.

(YN): Really?! You mean it?

Nanami: Don't make me change my mind.

(YN): O-Okay! Sweet! Thanks! ...Heh, you know? Gojo told me you would've been such a lame guy.

Nanami: ...Did he?💢

(YN): Heh, yeah, but...you seem like a nice guy. I hope we can get along more later, we might even fight alongside together sooner or later. That'll be so cool.

Nanami: ....*gently smiles* I'm looking for it. Anyways, let's get going and head to our plane.

(YN): Sure!

-END OF FLASHBACK-

Nanami Mind: ...Oh (YN)...I'm sorry...but, I know you're strong. I know you are, I can tell. So please...wherever you are...take care, and keep our friends safe. And....

Nanami looks back to Itadori...and giving him one final smile to him...and says his last words to him...

Nanami: Itadori....You got it from here.

With that said....his whole body began to transfigured...and yet his whole upper body exploded by Mahito, and killing him....and Itadori witnessing it...yet to loose someone again and taken by Mahito once again....
.
.
.

Itadori: N-Na..Nanami......wh-wha..what...NRRRGH!!!! WHAT THE HELL ARE YOU, MAHITO?!?

Mahito: YOU DONT HAVE TO SHOUT, I CAN HEAR YOU LOUD AND CLEAR, YUJI ITADORI!!!

Itadori charges to Mahito and ready to beat him up.
.
.
.
.
Meanwhile, outside of Shibuya, in the Dogenzaka Alleys, around 11:16pm...there, we see another Mahito.
.
.
If you're wondering how is Mahito there if he's about to fight Itadori...well, before that, Mahito, Jogo, Dagon and Choso were playing a "game" to whoever finds Itadori first, either kill him or feed him Sukuna's fingers to awaken him. While playing the game, Mahito duplicated himself to find Itadori easier. One to look for him in the station, and other outside of Shibuya...the one outside of Shibuya, he bumped into someone from Jujutsu High...

Mahito: Did you see that earlier? That was crazy. I was wondering around that area not that long ago.

And that Jujutsu High student is Nobara...

Nobara: Patch-Face! Was it you? Was it you that's been messing around with our idiot??

Mahito: Oh my my, hehe, am I really that famous??

Nobara: Yea, for running away like a little bitch, hehe.

Mahito: ...I like you, you seem worth to kill.

Nobara: Well I haven't had any chances to shine myself today. *If I remember, his technique has to do with transfiguring souls. Can't let him touch me.* So I'll have to give myself an exercise against a coward like you.

Nobara tosses her nails and to hit them with her hammer with her cues energy as the nails go straight to a sign board above Mahito and to fall in front of him, and Noabara to dash to that sign and to drop kick it to Mahito and hit more nails through the sign and going through Mahito's head.

Nobara: Hairpin!

The nails exploded and Mahito to bleed out from his head as Nobara backing away...

Mahito: Haha, not bad! But...in general, it won't work on me. *Judging from what she said, she must be close to Itadori. Then, I'll bring her dead body right to him, and destroy his soul! It'll be so laughable.*

.
.
.
Meanwhile, somewhere in Shibuya, we there see (YN) swinging around with his black webs and making his way over to go and find Nobara...

(YN): Hang on Nobara. Im on my way.
