Inside the academy classroom,
Tok… tok… tok…
Ayaka is walking back and forth with impatience.
"It's already an hour. How long do we have to wait?" She has a livid expression on her face.
"All other genins already left with their Jounin instructor." She folds her hands around her chest.
"Now… now… Ayaka! Don't be so impatient. I am sure the jounin must be held back by something. Also…"
Hanabi stares at the vacant spot beside her.
"Since we will form a three-man squad, we have yet to see our third member!"
Click…
The door is creaked open as two figures walk in.
"Oh!"
Ayaka's ears perk up as she curiously stares at the newcomer. But soon her expression turns to dismay.
A nine-year-old girl with long brown hair and light brown eyes enters the room. Her hairs are braided on one side and left straight on the other.
The girl is escorted by a masked anbu.
"Stay here and behave! Don't create any ruckus."
The Anbu warns her before he departs away.
"Oh! So, you are going to our third member!"
Ayaka curiously inspects the girl. She notices her pale color and flabby skin.
'Hmm… looks like this girl doesn't exercise often!"
"What's your name? My name is Ayaka Uchiha, and she is Hanabi Hyuga." Ayaka introduces herself.
She tries to initiate a conversation with the newcomer.
Hmph…
The girls snort and walk to a corner of the room.
Ayaka frowns at the attitude of the girl and her expression turns unfriendly.
"Whatever!"
She continues to stroll back and forth in the room.
"Oh!"
Izuna is monitoring the girls using the crystal ball in the Hokage Office
"So, that's the Kurama clan girl, Yakumo Kurama!"
Mm…
Tsunade nods her head.
"She has got quite the attitude!" Izuna stares at Yakumo.
Izuna walks towards the nearby sofa and lies down on it.
"…"
Shizune and Tsunade silently stare at him.
"Aren't you going to introduce yourself to them?"
Yawn…
"They can wait for another half an hour. I will take a quick nap."
Izuna closes his eyes.
"…"
"Well, whatever!"
Tsunade and Shizune return to their work.

In the academy classroom,
Hmph…
Ayaka puffs her cheeks in anger.
"When will the Sensei arrive? I am tired of waiting for him."
"Ayaka, maybe you should relax and sit down. Sensei will come eventually!" Hanabi tries to console her.'
"No, I am impatient because Onii-chan is waiting for me. I have to tell him about my new Sensei!"
Ayaka shakes her head.
She rummages through her storage and takes out a black ball.
"Since he likes to come late, then he shouldn't mind if I prank him a little!"
Ayaka has an evil smile on her face.
"But… but what if Sensei got angry?" Hanabi asks in trepidation.
"Daijoubu! Daijoubu! I will take full responsibility."
She tosses the black ball in her hand walks towards the door.
"This is a new Fuinjutsu tool made by Kushina nee-san!"
She places the ball against the door.
Swoosh…
The black ball sticks to the door and releases a sealing formula.
Whoosh…
The sealing formation crawls over the entire door and disappears.
Yakumo, who is sitting in a corner, raises her head. She curiously stares at the sealing formation.
'What if I temper with this door? I can get rid of this nuisance once for all!"
She takes out a painting scroll from her bag.
Fwoosh… fwoosh…
Yakumo quickly makes a few strokes of the brush and draws the door.
Fwoosh…
She makes a few more strokes and the door slightly changes. A guillotine appears at the upper hinge of the door.
Huh!
Ayaka frowns as she stares at the door.
'Just now, I sensed a strange chakra in this door.'
She curiously inspects the door for changes but didn't notice anything out of ordinary.
'Must be a figment of my imagination!'
She shakes her head and returns to her seat.
Ah!
Ayaka lazily rests against the desk.
"Ehto! Ayaka! What did you do to the door? What was that black ball?"
Hanabi curiously asks her.
"Oh, that! It's nothing major. It's a small ninja tool which upon contact with a person will trigger the seal and dowse the victim in black ink.
This is a special ink which will cause slight burns in the eye and the victim will turn blind for a couple of days."
"Oh!" Hanabi opens her mouth in an ellipse.
"But Ayaka-chan! That's too evil!" She shakes her head.
"What's so evil about it? It's a small trick from a genin. If a jounin can't even sense such a small trick, then I might not as well allow him to teach us. Also, that's what he gets for being so late." Ayaka snorts.
"Umm… that makes sense! But somehow there is something wrong with your statement." Hanabi shakes her head.
Half an hour later,
Yawn…
Izuna slowly opens his eyes.
"That was a good sleep. I must get going now!"
He cracks his neck and walks out of the room.
"This is Hokage Office! Not a public restroom!" Tsunade groans in anger.
Izuna ignores her and walks towards the academy.
He approaches the classroom.
Hmm…
He senses something odd about the door.
"Interesting!"
Izuna activates his Sharingan and investigates the door.
"A sealing formation and a genjutsu! This sealing formation must be from Ayaka and Genjutsu from that Kurama clan girl. Also, this genjutsu gives off murderous vibes. Looks like this girl wants to murder her Sensei!"
Izuna has an incredulous expression on his face.
"Does this brat really think she can kill a jounin with such a lousy trap?! Well, I will entertain them!"
"Yo!"
He steps inside the door and waves his hand.
Swish… Fwish…
Ayaka makes a hand seal and Yakumo makes a stroke of the brush.
"Release"
Clang… Swoosh…
A metallic guillotine with a sharp blade falls on Izuna's head and a dark blob of ink is hurled towards his eyes.
Clang… Puff…
Izuna raises his arm and grabs the blade with his bare hand.
Crack… crack…
The blade shatters in countless ink particles and disperses. A windshield appears in front of his face and blocks the ink blob.
"Nice attempt! I have to give you that. I will give you a score of six out of ten for an attempt to blind and kill your Sensei!"
Izuna flashes a smile at the trio.
Gulp…
Ayaka gulps her saliva.
"Nii-san! What are you doing here?" She asks in confusion.
"What am I doing here? Of course, I am here as your jounin instructor!"
Izuna has a devilish smile as he stares at Ayaka.
"Also, address me as Sensei when we are on a mission!"
"O… Ok!"
Ayaka nods her head as she clutches her head.
'What should I do? Onii-chan is my new Sensei, and I tried to prank him.'
She turns to Izuna, who has a silly smile on his face.
'I guess he deserved it for being so late!' She consoles herself.
"I will talk to you later for using the ink of the Poisonous Phantom Squid!"
He turns towards Yakumo.
"As for you, I will give you a score of four out of ten for your genjutsu. Although your genjutsu was powerful, it was in plain sight and thus easy to notice! I will show you what a real Genjutsu is!"
Shiing…
Izuna casts a powerful genjutsu on Yakumo.
Sweat starts to trickle from her forehead as she tightly clenches her fists. Her expression turns pallid as horror appears in her eyes.
Tick…
Izuna snaps his finger and dispels the genjutsu.
"This is what you call a genjutsu? What you are using is quite crude? You waste lots of your chakra and thus it is easy to spot the abnormality?"
Izuna lectures her.
"If you want to learn, then come to the roof for the introduction!"
He turns to Ayaka and Hanabi.
"As for you two! Follow me to the roof!"
Whoosh…
He flickers out of the room.
Sigh…
Ayaka heaves a sigh of relief.
"Let's go!" Both Ayaka and Hanabi follow him.
Umm…
Yakumo has a conflicted expression on her face.
Just now, she was trapped in a powerful genjutsu. These three seconds felt like three days to her. She was helpless to do anything while caught in the genjutsu.
"I… I… what should I do?" She helplessly stares at the roof.
"The other members of the clan call me a monster and imprisoned me in that mansion. These people of Konoha acts as the gatekeeper to that prison. They won't allow me to move out of that mansion.
What should I do? Will he really teach me?"
Various questions flash through her mind as the scene of that dark red sky with a black moon flashes through her mind.
"Yes! I will learn it. I have to learn it! I want to be a ninja and achieve my freedom."
She relaxes her fists and steps out of her room.

A/N:- Casting Tsukuyomi on a little girl might be too much for people's taste, but that's just a part of Izuna's personality. He is straightforward when it matters. Also, Yakumo is a special case if you know her story.
