In Shinji's secret laboratory.
Mumei, lying in the nutrient pod, slowly opened her eyes, and the first thing she saw was Shinji's face, filled with concern.
"Shinji!"
Seeing him, Mumei felt an inexplicable sense of reassurance.
Shinji quickly asked, "How do you feel?"
"Feel? Hmm…" Stretching lazily, Mumei said, "My body feels much lighter. I haven't slept this well in ages!"
Shinji nodded while starting to record.
Seeing him meticulously noting in the experiment log, Mumei leaned in curiously. "Shinji, what are you writing?"
"Of course, I'm recording your physical condition!"
With that, Shinji pointed to the data in the log, explaining it to Mumei.
As he had predicted, Mumei's body was severely depleted, sustained purely by the hegemony of 'Yachihoko.'
After the first round of slumber, her cells had not only replenished sufficient nutrients but were gradually adapting to the unsealed state, slowly getting back on track.
After hearing Shinji's explanation, Mumei nodded vaguely. "So, you're saying my body is starting to recover? When can I use my Sharingan again? I still haven't returned the Mangekyo dojutsu you entrusted to me!"
Shinji said, "In your current state, you can use your Sharingan, but not excessively!"
"Really!"
Mumei's face lit up, and her dark pupils instantly turned a vivid scarlet! Looking at the Mangekyo Sharingan in her eyes, radiating an eerie glow, for a moment, even Shinji felt as if his soul was captivated.
Snapping out of it, Shinji said, "What a beautiful Mangekyo!"
"Really?" Mumei grinned, then asked, "By the way, you still haven't told me why you lost your dojutsu. Is something wrong with your Sharingan?"
Shinji shook his head and removed his tinted contact lenses.
Without the dark lenses concealing them, his pale purple Rinnegan immediately caught Mumei's gaze.
"What's this?"
Mumei froze.
The powerful intuition granted by 'Yachihoko' told her that Shinji's eyes were far more powerful than the Mangekyo Sharingan! Shinji said calmly, "They're called the Rinnegan. You can think of them as an advanced form of the Sharingan!"
Mumei stared intently at Shinji's Rinnegan, whispering, "So the Mangekyo Sharingan can evolve further? That's incredible!"
Shinji explained, "The Mangekyo Sharingan is actually unstable."
Mumei nodded. "Mm, mm, I know. The clan said that Mangekyo Uchihas always end up in complete darkness and despair! That's why they called the Mangekyo Sharingan a cursed eye, and those of us who awakened it are cursed! But for some reason, my vision never deteriorated, so they treated me as an outlier!"
Shinji smiled. "No, the Mangekyo Sharingan causes blindness not because of a curse but simply due to insufficient dojutsu power."
"Huh!?"
Mumei was shocked, her common knowledge shattered.
But she had grown to trust Shinji, so instead of arguing, she widened her eyes, waiting for his explanation.
Shinji continued, "Above the Mangekyo Sharingan, there's another form of Sharingan I call the 'Eternal Mangekyo Sharingan.' Once you have it, you're no longer plagued by the loss of dojutsu power or blindness."
Pointing at Mumei, he added, "As for you, the reason your vision hasn't deteriorated is simply because 'Yachihoko' can replenish dojutsu power! You're not an outlier—you're just luckier than others!"
Mumei pursed her lips. "Thank you, Shinji!"
Shinji said, "Why thank me? I'm just stating the truth!"
Mumei started counting on her fingers. "Sharingan… Mangekyo Sharingan… Eternal Mangekyo Sharingan… Rinnegan… So there's such a long gap between the Mangekyo Sharingan and the Rinnegan! Shinji, can I awaken the Eternal Mangekyo Sharingan and Rinnegan too?"
"Of course!" Shinji paused, then said, "If we factor in 'Yachihoko,' you might even have an easier time than I did. But once you awaken the Rinnegan, you can't use Sharingan dojutsu anymore. Are you willing to give up 'Yachihoko'?"
"So that's how it is!"
Mumei instantly understood why Shinji had lost his 'Jikibi,' 'Wazunagi,' and 'Susanoo Tomoshibi.'
Shinji sighed. "Before awakening the Rinnegan, I didn't know what would happen to my Eternal Mangekyo Sharingan dojutsu. Only after awakening it did I realize I couldn't retain both the Sharingan and Rinnegan dojutsu. That's just how the world works—things rarely go as planned!"
Mumei suddenly grabbed Shinji's hand. "Shinji, you've helped me so much. This time, I want to help you!"
"Help me with what?"
Shinji chuckled.
He knew 'Yachihoko' was powerful, but it likely couldn't transfer Mangekyo-level dojutsu so easily.
That's why he hadn't asked Mumei to try before.
Seeing Shinji's skepticism, Mumei insisted, "I can do it, I really can!"
Shinji patted her shoulder. "Alright, I believe you. Let's give it a try! But don't push yourself too hard. If it doesn't work, it's fine—as long as those dojutsu are still recorded in your Glowstone, I'll definitely find a way!"
"Mm!"
Mumei agreed, then summoned the Glowstone tied to her and Shinji.
Seeing the Glowstone that recorded every moment of their connection, Shinji couldn't hide the amazement in his eyes.
Mumei tightly gripped Shinji's hands. "Shinji, get ready. I'm about to activate 'Yachihoko'!"
Since Shinji himself possessed abilities similar to 'Yachihoko' with 'Jikibi' and 'Wazunagi,' he was already prepared. "Begin!"
Boom
As soon as Shinji spoke, a massive surge of chakra flowed from Mumei's body into his.
"This!?"
Shinji was stunned.
The chakra Mumei transferred was far purer than he'd expected, almost instantly usable without refinement.
At the same time, he faintly sensed something returning to his body along with the chakra.
Thud
Mumei suddenly collapsed weakly to the ground.
Reacting quickly, Shinji crouched down. "Mumei, are you okay? I told you not to overdo it—why did you transfer so much chakra to me?"
Pale-faced, Mumei stared at Shinji's eyes and exclaimed joyfully, "Shinji, magatama have appeared on your Rinnegan!"
