At night Akashi was peacefully sleeping in his large and comfortable bed, when...
"Swoosh, slash,"
He shouts out of his bed in an instant avoiding a slash that cut through on his bed.
His sharp eyes opened wide revealing his blazing sharingan.
The seals on his hands activated and his swords appeared in his hands.
"Clan, clank..."
In an instant, he confronted the assailant in the darkroom using his full strength and speed, and with his Sharingan, he was able to distinguish the assailant's chakra flow.
The sound of weapons clashing resounded in the room while sparks flew everywhere.
'he is strong, who is it? I can identify his chakra signature," Akashi thought his swords started gleaming charged with chakra.
He was about to send one of his slashes toward the opponent when
"Alright it's enough, you did well,"
"I recognized that voice, Old man!" Akashi exclaimed in surprised
'His chakra signature now,' He thought the light permeated the room revealing the appearance of the Kuroko
"You! Why, how!?" many questions appeared in Akashi's mind in a split seconds before he regained his calm
"The room is destroyed," he said looking around, the room that was fine barely a few seconds ago was now in disarray, the walls were marked by traces of the clash, and the furniture was overturned.
"Good Reflex," Kuroko said putting the kunai he was holding away.
"What was that, a new form of training," he asked looking at Slash that the old man had made on his bed.
"You would've slashed my throat if I didn't move," he complained angrily.
"No! Just the forehead," the old man corrected nonchalantly,
"How did you escape my perception? And why wasn't I able to identify you?"
"Not now," The old man interrupted him.
"It's not just for training that I woke you Up," He said looking at Akashi seriously.
"The why!?" He replied with a questioning gaze.
"She started to move," the old man said to Akashi
"Ah," he exclaimed
"the monitor," he thought trying to reach toward it to look through the miniature cameras that had been put in Karin's room.
The moment that it was confirmed that she was under hypnosis she was put under surveillance by the old man.
While he was reaching for his laptop he was stopped by Kuroko.
"You will use the mind eye to spy on her,"
"What!? You know that I'm not at her level she will notice me the moment I start trying," he remarked as it wasn't the first time he did.
"No, she won't, not right now! She isn't in the right mind right now or she would've noticed the commotion in the room,"
He said and Akashi realized that this attack was a way to test Karin too.
"Hm, I see, alright!"
With that, he closed his eyes.
Activating his mind eyes his field of vision changed, it was like his soul was floating above and he was seeing everything from a third-person point of view.
He was seeing the whole room from above his body standing still and the old man beside him.
"One second the old man said putting his hand on his head.
He immediately felt the vast and deep spiritual energy of the old man surround him.
"I will guide you," he said "Even though she is under hypnosis we need to be careful."
"Alright!"
He responded casting his gaze toward the room of Karin, his spiritual perception expended passing through the walls.
"Hm!"
Before he could look inside the room with his mind's eye he felt it,
Karin's spiritual energy, dense yet subtly, was carefully woven around the room stopping anything from entering without alerting her.
That spiritual energy was like a cocoon around the room.
"I don't see how I can bypass that shield," Akashi said observing from all sides.
'Not even by the ground.' he thought and it was at that moment that Kuroko finally talked.
"How did you think that I infiltrated your room without you noticing even though you have a similar spiritual shield around you,"
"Mine is nothing like that!" he said admitting that compared to Karin he was very making in that domain.
"Doesn't matter how you think that I did it, bypass all your defense to attack you in your sleep and how did you even though I was right in front of you evade your spiritual probing,"
'Because you are old and decrepit,' he thought.
At the moment that thought crossed his mind he was struck on the back of the head by the old man, it was strong enough to hurt him but not enough to make him lose his control.
"Don't be rude,"
"How! Can you read my mind?"
"I am in contact with your spiritual energy, I can't read your mind, just feel your mood!"
"I see!" he said thinking if he would be able to do something like that later.
After that, he refocused on the task at hand,
"I honestly don't know," he responded truthfully
"Spiritual perception isn't infallible, there are techniques that allow you to bypass or trick spiritual perception, but that's not what I want you to use, I want you to feel the hole in her defense," the old man explained.
"Holes!"
"There is no infallible technics, particularly spiritual energy, it is harder to control and even harder to train,"
"I'm going to show you," Kuroko said
Akashi felt chakra penetrate his mind from Kuroko's hand.
His eyes shout opened in shock, his already red eyes became even redder.
"What is it?! I can see it," he thought.
Before he was only able to feel Karin's energy, but now he could vaguely see it.
"I see it, the hole too, but it is vague!"
"Of course it is vague, you are only seeing it through me," the old man said
"This is moving, now that is see that it seems like a fluid, like a chakra," Akashi said as he looked at the spiritual energy around Karin's room move.
"Of course it's move, this is a form of energy, the thing is to get control over that energy and make it yours,"
Seeing that he realized that he didn't know a lot about the spiritual energy, even though he was able to use it quite well.
'So it's moving, huh, it's like fluctuation, and if you're able to see that fluctuation you can nearly spy on everyone,' he thought.
'Wait he said that there are techniques capable of tricking spiritual perception, I shouldn't be too cooky about it,'
After that under the support of the old Kuroko, he was able to bypass Karin's defense and enter the room.
'There she is!' he thought he was able to see Karin in a nightgown
"She has a Sharingan in her pupils," Akashi said in astonishment
"Yes, it isn't a simple hypnosis, it seems to be one of the most advanced forms of use of the Sharingan,"
"I see,"
"What is she writing?" he asked
"A rapport," The old man responded "She has been at that for a while now, it is a rapport of everything she has learned since she arrived here,"
"Should we stop it? She is writing about Kushina here right,"
"I doubt this is something they won't be able to verify, with those white creatures, what matters to me is that she didn't share all the details of our plans and even lied to her about a lot, so there is no need, look and you will see that,"
At that, Akashi started to read what she was writing
"That's right, and she doesn't seem to write anything about things that happened before she was hypnotized,"
"Maybe you were right when you said that we may be able to use it to our advantage," he said
After he said that she stopped writing.
"She is done,"
After wrapping the scroll they saw her make a few hand signs before a white mass appeared in white smoke.
"tap," at the moment that it appeared Kuroko grabbed Akashi's head harder wrapping his spiritual energy around his hiding them from the new spiritual energy that appeared in the room.
'Is it another Zetsu, it looks like some kind of white flesh.'
Taking the scroll she places it on the white fleshy things.
They then saw the scroll disappear in it before
"poof," the thing disappeared in another white cloud.
After that, she just got up and returned to her bed, before the Sharingan disappeared.
"She is asleep," Kuroko said
"Yes, she is,"
Akashi reopened his eyes in his room.
"I need to convince my grandfather to give me access to the library of the Uchiha..."
"...Or maybe you can try to stires the conversation on the subject once when you have established contact or a deep connection with him,"
"Yes,"
"Go back to sleep you're going to be really busy in the next couple of days or months,"
After Kuroko disappeared Akashi spent a lot of time thinking about how to free Karin from the control of Madara,"
