==================
"How is that possible? That thing called Rasengan is so small but has so much destructive power," said Jonin to Uzukage.
"What a shock it was, you can use it without even a seal," another Jonin also said about it.
"This guy, it's not a mistake to marry my daughter to him. I think we need to... Wait, what is that?" said Uzukage.
Suddenly, the Rasengan turned into Rasen Shuriken.
"The first one is Rasengan, and the second one is Odama Rasengan. Now I will show you the third form of Rasengan, which is Rasen Shuriken." Setsuna used kage bunshin no jutsu, and a few seconds later he raised a big Rasen Shuriken. "This is the third form, I called it Rasen Shuriken."
(A/N: The third one need Wind Chakra. Someone told me in the comment, only rasen shuriken need wind chakra. The rasengan didn't need)
Setsuna then cancelled out Rasenshuriken because he didn't master Senjutsu and this Rasen Shuriken needed to be thrown. Before this, he practised several times throwing it but failed because it would disappear completely before it managed to reach the target.
"Now this is the Jutsu that I will teach you after you graduate from Ninja Academy," said Setsuna with a grin.
"Woah, I really wanted Setsuna Sensei to become my teacher."
"No, he will choose me to become his student."
Several students said about today's lecture and how excited they are. Before this, a teacher in the academy always taught them about sealing Jutsu. But today was the first time they could see S-Rank Jutsu from another person, so they were really excited to become Setsuna disciples.
On the other side, several Ninja also show some jealousy and opinions about Setsuna.
"I really envy these kids, during our time, we were busy learning fuinjutsu."
"It can't be helped, now the ninja world is very peaceful compared to the past, when it was chaotic."
"I thought Uchiha were cold, but I'm wrong, they are like us too."
"Uzukage's decision to let him teach the student is really the right thing."
AT HOME....
Setsuna looked back at the diagram he drew earlier, this diagram is to evolve Sharingan to Mangekyou Sharingan. If his experiment is successful, Uchiha will become strong like Senju without even needing to sacrifice their own people.
Senju is strong because of their body, and Uchiha is strong because of their eyes, but Uchiha needs to pay a heavy price to open this eye. There is a need to be stimulated and lose their loved ones, but this will result in them having an extremely negative mentality like Madara.
With the blessing he got from the system, his mastery in fuinjutsu can be graded SSS+, and it is extremely easy for him to create a new sealing jutsu or crack an old seal. So with his knowledge, he tries several seals and needs a test subject.
1. Sealing Emotion Jutsu
With this seal, it will create a jutsu, which can trigger angry and sad emotions. The probability sharingan will evolve is amaterasu and flame control.
He remembered Sasuke gaining Amaterasu because he was in an extremely angry condition after knowing the truth about his brother's rebellion. He wanted to destroy everything, and thus Amaterasu was born.
2. Sealing Machine: Virtual Reality
This is the same as Apple Vision Pro or Meta Quest, but the user will enter the dream like State. They will experience war and lose the closest people they wanted to protect.
With this MVR, some of them might develop kamui and many other Mangekyou Sharigan abilities.
3. Seal of protection
Because of the special chakra, it will prevent the special chakra from entering the heart and changing their emotions.
Setsuna then seeks Kagami to give him this seal, and because Kagami is his precious disciple, he chooses the second seal. This second seal is a bit like the NV Link that connects to the brain. To make sure this test is a success, he needs to fool Kagami first.
"Kagami, come here," said Setsuna.
"I'm here, Sensei," replied Kagami after entering Setsuna's personal lab.
"Today, I would like to give you an extra boost. This seal will make your body stronger. I need you to lie down there for me to fix this on your head," ordered Setsuna.
"What is this, Sensei?" asked Kagami.
"Oh, this one is a special seal that I develop to increase the amount of chakra. Lie down there; I need to fix this on your body." Setsuna lied to him to make sure this experiment was successful.
After everything has been put into the body, Setsuna then makes a horse seal to activate MVR.
Kagami, who didn't know the real purpose of this MVR seal, suddenly found his teacher saying the experiment had failed. After that, he was told to get ready with Chino to fend off the enemy that tried to invade Uzushiogakure.
The enemy is too strong, and while his teacher is busy, suddenly 100 enemies come and kill Chino. Setsuna came and fended off the enemy. Kagami, who saw Chino in critical condition, tried to heal her, but to no avail, she became very weak. He hopes this is just a dream, but Chino died by his side.
"No.. No.. This can't happen," shouted this 13-year-old boy, Kagami. "Chino, please, I wanted to grow older with you. Please don't die, there are so many things I wanted to do with you."
"Sob, Sob, Sob," Kagami cried, he suddenly heard a voice. "Why are you crying?"
When Kagami opened his eyes, he saw the injured Chino was missing, there was no blood, and he still lying down in the lab.
"Sensei, How?" Kagami is confused about what happened to him. Suddenly, Setsuna passes a mirror to him. "Look into your eyes"
