"As for the troublesome stuff!"

Izuna grabs Boruto's right hand. There is a diamond-shaped Kama mark on Boruto's hand. Izuna activates his Rinne-Sharingan. ​​

Shoom…

He appears in a mental plane.

A pale figure with pale-blue hair tied in a long ponytail appears in front of him. His hairs are parted in a zig-zag pattern and his head is adorned with a pair of flat, curved horns.

"Gokigenyou! I never expected a low-life like you to intrude in this place. You do possess a certain level of ability to fight on the equal front with us, noble Otsutsukis!"

Momoshiki activates his Byakugan as he gazes at Izuna.

Izuna raises his head and stares him in the eyes.

Tsk…

"You sure talk a lot for a dead man!"

Izuna smiles at him.

"Humph… you low-life were lucky to be able to kill me." Momoshiki harrumphs at him.

"Low-life! If I am a low-life, then what are you? A parasite?! Feeding on others to sustain your existence!"

"Shut up! You lowly being! How dare you insult a noble Otsutsuki?!"

Momoshiki activates his Rinnegan, ready to attack Izuna at any moment.

"Oh! Looks like I hit the sore spot!" Izuna slowly walks in front of Momoshiki and confronts him.

Both of their eyes meet each other as Momoshiki peeks through Izuna, trying to figure out his secrets.

"Momoshiki! You are trying to ride the coattails of this child of destiny to preserve yourself in the upcoming chaos! Do you think you have what it takes to survive in this turmoil?"

Haha… Ahaha…

Momoshiki laughs hysterically and remarks.

"An insect-like you think he knows the big picture of the world! You aren't even worthy of being a pawn in this game!"

Haha…

Izuna burst out in laughter as he activates his Rinne-Sharingan.

"No!"

Shoom…

The surroundings change as a large torii gate falls from the sky and pins Momoshiki down. The Torii gate suppresses Momoshiki as the latter is unable to even resist slightly.

"I am not a pawn! I am a beater!"

Shiing…

Izuna reveals his Rinne-Sharingan to Momoshiki.

"It can't be!"

Momoshiki is horrified to see Izuna's Rinne-Sharingan.

"That pattern! How could it be?"

Cold sweat runs down Momoshiki's spine as he notices Izuna's Rinne-Sharingan.

"Do you still think I don't possess the abilities?" Izuna calmly stares at Momoshiki.

Hmph…

"So what?! Even with your eyes you 're nothing more than an ant! Fodder for the truly powerful beings!" Momoshiki scoffs at him as his nerves calms down after the initial outburst.

"It's indeed true that the current me is too weak to wield this power. But in this mental space where I am not restricted by the limitation of my body, you are nothing more than a worm in my eyes."

Izuna swings his arm as the torii gate presses on Momoshiki, pinning him to the ground.

"I can easily squash you if I want. But I will give you an opportunity!" Izuna slowly walks in front of Momoshiki.

"Hmph… do you honestly think I will agree to you?!" Momoshiki scoffs at Izuna.

"No! I don't believe you will agree, I am sure you will agree!"

Izuna has a smile on his face.

"As far as I can see, you lot are nothing but disposable pawns. But I can see the will to survive burning brightly in your eyes. This is part of the reason you cling to Boruto's fate.

Also, you don't hold any considerable power among Otsutsukis, or else they would surely have taken measures to save you! What does this mean? Either you fulfilled your job or you have lost your usefulness." Izuna smirks at him as he stretches his arms.

"Don't tell me you are also a disposable pawn!"

"You!" Momoshiki's face turns ugly as a figure with crown-shaped horns flashes in his mind.

Tch…

"Fine, I will agree with you! But don't think a measly human like you can control the likes of me!" Momoshiki clicks his tongue.

"Of course! I am proposing a partnership beneficial for both of us! Help this boy with his growth and in return, I will help you with your ambition!"

Izuna walks near Momoshiki and whispers something in his ear.

"What?!"

Momoshiki's eyes widen in shock.

"Fine! I get it!" He nods his head.

"Haha… I was right! You will agree with me! Death sure has toned down your aggressive character!"

He pats Momoshiki's back.

"I won't ask you to utter any Otsutsuki secret since you won't be able to reveal anything either way!"

Izuna walks towards a white gate that appears in the mental space.

"But I am sure, you will be of great help in other matters!"

Izuna steps through the gate and disappears.

"Damn! This human thinks he can manipulate me!"

Momoshiki grinds his teeth.

"Just you wait!"

Swoosh…

Izuna opens his eyes and smiles at Boruto. There is a circular seal around the Kama.

"You don't have to worry about this Kama seal for a while."

Phew…

Sasuke heaves a sigh in relief. One of his purpose besides dealing with Urashiki was to seek Izuna's help with Boruto's Karma Seal. This seal is like a ticking time bomb and it was partially their fault for dragging Boruto through that incident.

"Now then! It's time to return!"

Sasuke pulls out Karasuki from his storage.

"Sasuke-sama! Karasuki at your service!" The turtle briefly opens its mouth.

"Here!"

Izuna feeds some of his chakra to Karasuki, as Karasuki greedily sucks it all.

"Destination confirmed! Initiating Temporal Shift in…"

"Hold on!"

Izuna pulls out a scroll from his pocket and passes it to Tatsuya.

Tatsuya tilts his head in confusion.

"This scroll is the amalgamation of all my Ninjutsu, Genjutsu, Kenjutsu, Senjutsu, Fuinjutsu, and Taijutsu technique. This is the path I walked on. I hope for you to learn from my mistakes and take a path of your own. I hope one day, you will surpass me in the future!"

Izuna smiles at his son.

"Of course!"

Tatsuya dashes towards him and hugs him.

"Dad! I will keep my promise!"

"Now! Now! Don't make me tear up even before you are born!" Izuna chuckles and pats his head.

3…

2…

1…

Izuna steps behind as a temporal bubble forms around Sasuke and the group. He activates his Rinnegan to spectate the process.

'This temporal shift involves Time-Laws. If I can figure out even a fragment, my time-related abilities will improve vastly.'

Izuna records the entire process with his Rinnegan.

'I will study it during my free time.'

Shoom…

Blue energy flickers out from the bubble and it vanishes with a flash.

"So, these are so-called temporal tunnels." Izuna notices a portal irradiated with blue energy.

The portal is slowly closing as the energy supporting it dissipates.

"Guess, I will return to the clan!"

--------------

Back in the future,

Swoosh…

Another portal opens on top of the Hokage Office.

"They are back already!"

Minato, Naruto, Mei, Tsunade, Kakashi, Shisui, Itachi, and Shikamaru warily stare at the portal.

Whoosh…

Three-figure jumps out of the portal and lands on the roof.

"Onii-chan!"

A tall slender figure with fair skin jumps in Tatsuya's embrace. The figure has black eyes and ankle-length, auburn hairs with a tint of blue at the end. Two short bangs are framing the sides of her face, covering her eyes slightly.

She wears a long-sleeved black dress that falls just below her knees. The Uchiha symbol is imprinted on the back of her dress.

"Yes, I am back, Kanna!"

Tatsuya ruffles her hair.

"Ne… Ne… Onii-chan! Tell me more about father! How much different was he in his youth!" Kanna curiously asks him.

"Alright! I will tell you everything. But before that…"

Tatsuya takes out a scroll from his pocket and walks towards Mei.

"Mom! It's a souvenir from dad! He especially asked you to open it as soon as possible or it will be spoiled!"

"Oh!" Mei curiously takes the scroll from his hand and opens it.

Poof…

With a puff of smoke, a bento packed in a blue cloth appears in front of them. A mouth-watering fragrance wafts in the air

"This fragrance…"

Mei hurriedly unpacks the bento as the layers of well-cooked steak appear in front of her.

"It surely is…" Tears rolls from her eyes as she gently picks up a piece of steak and nibbles on it.

"This taste… I have been yearning for years… it is still the same taste!"

Mei wipes her tears and savors the steak.

Kanna and Tatsuya are surprised to see their mother like this. It has been almost ten years since their father left them, but until now they never saw tears in their mothers' eyes.

"Tatsuya, Kanna! These steaks are the reason I fell in love with your father."

Mei closes her eyes as she reminisces about the moments when she first met with Izuna and later how the latter would cook these steaks in wild.

On the side,

Sasuke explains the turn of incidents to the group.

"As expected of Izuna! He is always so mysterious!" Minato shakes his head.

Swoosh…

Suddenly, the surroundings turn dark as a gigantic portal opens in the sky.

The expression of the group turns ugly as they stare at the portal.
