He was too embarrassed to say it out loud, or else that arrogant Kakashi would make fun of him again. Actually, Kakashi probably wouldn't make fun of him; if Kakashi were an Uchiha, he'd probably be able to awaken a Revolving Sharingan with three tomoe too.
He hadn't expected Rin to hold such a significant place in his heart, but he thought it was only right. His clan sister often cared for him and never disdained him for being a dead last.
Rin often encouraged him. If he hadn't fallen for Rin first, perhaps he would have fallen for a wonderful girl like Rin.
Obito indeed had great talent in Sharingan; he awakened a Revolving Sharingan with three tomoe right away. Next time, killing Rin Nohara in front of him should allow him to awaken the Mangekyo, Rin thought maliciously.
Rin walked up to Shisui, intending to check what was going on. Obito said he suddenly fainted, but Rin saw that Obito had already awakened his Sharingan, so she had a certain guess about Shisui's fainting.
As Rin expected, Shisui's brain and eyes harbored a powerful and cold Yin Release Chakra, and its quality far surpassed the Doujutsu of Rin's Revolving Sharingan with three tomoe.
It was clear that Shisui had awakened the Mangekyo Sharingan, though she didn't know if it was still Kotoamatsukami. Unfortunately, Shisui was currently unconscious.
Shisui's unconsciousness was caused by the overly intense stimulation of negative emotions causing brain mutation, coupled with the impact of the Yin Release Chakra generated by the Sharingan's evolution on his brain.
Awakening the Mangekyo at eight years old was truly too early. Shisui's body in all aspects could not support a pair of Mangekyo Sharingan.
In the future, his body would be worn out, just like Itachi in the original story, suffering from a severe Bloodline Limit disease. Shisui's Bloodline Limit disease might even be more severe.
The inherently evil Senju Tobirama was right; Uchiha who awaken the Sharingan will have their personalities affected to varying degrees, and Uchiha who awaken the Mangekyo Sharingan will inevitably become extremely stubborn and eccentric in some aspect.
Their external manifestation is somewhat like a mental illness, appearing broken, often unable to control their crumbling expressions. They themselves believe they have awakened, that they are no longer their old selves, and do not need the understanding of the world, even if they are misunderstood by the world.
However, she wasn't without a way to solve Shisui's problem. She just needed to give Shisui a White Zetsu Mark that only produced Yang Release Chakra.
But she certainly couldn't do that now. Revealing her researched black technology in broad daylight would cause huge trouble.
"Rin, how is Shisui?" Obito watched Rin finish her examination and then space out, immediately unable to resist asking.
Rin turned to look at the concerned gazes of everyone present. Rin's conscience couldn't help but ache, because she was about to lie again. She couldn't tell them yet that Shisui had awakened the Mangekyo.
Shisui awakening the Mangekyo at such a young age, whether Sunagakure or Konoha knew about it, would not be a good thing for Shisui or the Uchiha.
The Village was extremely wary of the Mangekyo. Rin planned to tell them in a few years. Konoha's corrupt higher-ups might not have the magnanimity to not be wary.
"It's nothing. He just thought I was dead, couldn't believe it, and was too pained, which triggered his body's self-preservation mechanism and forced him into unconsciousness."
Rin used the Reversal Technique to repair some of Shisui's damaged brain nerves, and then used Sage Art Chakra to place a Sage Art Sealing Jutsu on Shisui's brain.
This Sealing Jutsu was only to temporarily seal the already awakened Mangekyo Doujutsu, to prevent Shisui's Revolving Sharingan with three tomoe from turning into Mangekyo if he got emotional.
It also prevented Shisui from overusing the Mangekyo, leading to Doujutsu depletion and then blindness. The Mangekyo recovers Doujutsu extremely slowly, measured in years.
But once the Doujutsu is used up all at once, it will lead to the Mangekyo Sharingan inevitably synthesizing a large amount of Mangekyo Doujutsu, causing the Mangekyo Sharingan to suffer a backlash, damaging the eye structure, and leading to blindness.
Having Yang Release Chakra makes it easier, or fusing with a close relative's Mangekyo to stabilize the Mangekyo Sharingan's structure will also prevent blindness.
This Sealing Jutsu is a safeguard. The process of Shisui's Mangekyo Sharingan slowly accumulating Doujutsu will not cause the Mangekyo to activate.
However, once the threshold for using Doujutsu is met, the Mangekyo will activate. By then, Shisui should be around ten years old and able to barely withstand the Mangekyo Sharingan.
At that time, Shisui's own status would have touched the Kage-level limit, and he wouldn't be overly reliant on the Mangekyo, like Sasuke who went blind in a few months.
However, how long this seal can last is hard to say. The erosive nature of Yin Release Chakra is too strong, plus the unavoidable emotional fluctuations causing internal and external Doujutsu clashes, the Sage Art seal probably won't last for several years.
When there's an opportunity, she'll still put a White Zetsu Mark on Shisui. During this time, Shisui's strength will increase due to the Mangekyo.
After all, the essence of his eyes is already Mangekyo, so even if it's a Revolving Sharingan with three tomoe, it's much stronger than the original Revolving Sharingan with three tomoe. Coupled with his own Chakra growth, Shisui should be able to possess Jonin level strength through genjutsu.
Rin was somewhat envious of Shisui awakening the Mangekyo Sharingan. Rin's Sharingan evolution didn't follow the path of negative emotional stimulation.
Instead, it was a passive evolution triggered by the qualitative change in mental power caused by the increase in Curse Power obtained from subduing shikigami, but it also had the effect of Rin's long-term practice of Reincarnation Technique to strengthen her soul.
With the promotion of Sage Art Chakra and Curse Power, Rin was able to awaken her Revolving Sharingan with three tomoe at this age. Others relied on the Sharingan to promote the strengthening of their spirit and soul, while she relied on the strengthening of her soul and spirit to feed back and evolve her Sharingan.
Currently, Rin's physical fitness and mental power are capable of supporting the Mangekyo Sharingan, but to awaken the Mangekyo, Rin estimates she needs to subdue the strongest Mahoraga to have a chance.
Rin is currently practicing the'Sitting in Oblivion' state of the Reincarnation Technique. Her soul can already barely wander outside her body, but to enter an enemy's body with her soul to attack their soul, she still needs more practice.
Rin is not used to the feeling of her soul leaving her body, it's like dying, and the connection with her body is very weak. This feeling of weakness makes Rin, who is accustomed to a powerful physical body, extremely dislike it.
Moreover, the soul leaving the body is too dangerous for the physical body. Didn't Kato Dan, that idiot, die that way? He even wanted to become Hokage by relying on the Reincarnation Technique, but that's not how you dream of a pipe dream.
Not long after Rin sealed Shisui's Mangekyo Doujutsu, Shisui slowly regained consciousness. His brain and eyes no longer stung, and he seemed to have heard Rin's voice.
Wait, Rin's voice? Did he and Rin both die? He was truly useless, not only couldn't he protect Rin, but he also died himself.
Rin hesitated whether to tell Shisui about awakening the Mangekyo and her sealing of his Mangekyo Doujutsu, but after thinking about it, she decided to tell him.
After all, many relationships break down starting with concealment. Rin couldn't let Shisui, this good helper, betray her. She couldn't be like Minato when he became Hokage, having no Kage-level subordinates, only Kakashi and Shiranui Genma, those three Special Jonin, to hold the fort.
