Setsuna roughly explained, "These are realms I comprehended in the living world. The Sixth Sense is consciousness perception, capable of transcending the perception of the material plane and touching the realms of mind and spirit. The Seventh Sense is time perception, allowing glimpses of fragments of past and future. So, simply manipulating the five senses indeed has limited significance."
After hearing this, Aizen felt somewhat dejected. "It seems I truly lack the talent to become a real powerhouse..."
Yoruichi couldn't help but retort, "Don't listen to his nonsense. How many people in this world can transcend the five senses like him? For the vast majority, Kyoka Suigetsu's ability is already powerful enough."
Setsuna, however, shook his head. "Is being better than most people enough? Since you choose to follow behind me, you must have the belief to 'stand in the heavens'. It is precisely because I see his potential that I believe the future him can stand at the pinnacle of the world alongside me."
Aizen's heart trembled, filled with an indescribable surge of emotion, 'I never expected Setsuna-nii to think so highly of me.'
At the same time, a deeply buried ambition quietly ignited within him: 'This world should not be ruled by mediocrity. Only people like Setsuna-nii and myself were worthy of dominating this world's future.'
"I will teach you to comprehend the Sixth and Seventh Senses," Setsuna said, looking at Aizen. "If you can develop Kyoka Suigetsu to a level where it can dominate the Sixth and Seventh Senses, then it can truly be called powerful."
Yoruichi raised her hand. "I want to learn too!"
"Fine," Setsuna nodded in agreement.
Aizen asked further, "I just heard you mention the Eighth Sense, Setsuna-nii. What is that?"
"The Eighth Sense transcends the boundary of life and death," Setsuna's expression turned serious. "If you can develop Kyoka Suigetsu to the point of dominating the Eighth Sense, you might be able to hypnotize the will of the Soul Society itself, manipulating this world's rules. For example, hypnotize the Soul Society into believing a dead person is still alive. Then, the deceased might truly be revived."
Both Aizen and Yoruichi were inwardly shaken, 'Could anyone truly be powerful to such a realm?'
At this point, Setsuna turned to Yoruichi, giving a solemn warning. "Regarding Aizen's ability, do not reveal it to outsiders."
Yoruichi was still somewhat puzzled. "Wouldn't showing his potential allow him to receive better nurturing?"
"Aizen's ability is prone to arousing suspicion from the upper echelons," Setsuna said meaningfully. "You'll understand in the future."
Yoruichi puffed out her cheeks, glaring angrily at Setsuna.
'Again with 'you'll understand in the future'. Father was like this, now Setsuna too. Did they both treat me like a child?'
…
On the training ground, fluctuations of Reiatsu spread like ripples.
Setsuna held a wooden sword, using precise and restrained attacks to guide Yoruichi's movements.
Their figures intersected in the empty dojo, the crisp sounds of wooden swords colliding echoing in the air.
Fine beads of sweat formed on Yoruichi's forehead, her breathing gradually becoming labored. But her eyes grew sharper. She could feel a certain boundary was being broken.
Suddenly, Setsuna intensified his assault. The wooden sword shot toward Yoruichi's chest with a sound of parting air.
Yoruichi felt an inspiration. The Asauchi in her hand suddenly crossed a certain limit, arriving later yet striking first, parrying Setsuna's attack.
In the next moment, Reiatsu surged from Yoruichi like a tide. Her Zanpakuto emitted a clear, vibrant hum.
The blade shimmered with a faint purple glow, its form beginning to undergo subtle changes.
Setsuna withdrew his sword and stepped back, a pleased smile appearing on his face. "Congratulations. You've finally attained Shikai."
Yoruichi looked down at the Zanpakuto that had completed its Shikai in her hand, feeling the surging increase in power within her.
But the joy lasted only a moment before being replaced by another emotion.
She looked up, glaring at Setsuna with great indignation. "You attained Shikai in one day. That guy Aizen only took three days. But I spent a full seven days… more than both of you combined!"
Hearing this from the sidelines, Aizen sighed helplessly and thought to himself, 'It seems I still stood out too much.'
Omaeda, standing nearby, felt like crying but had no tears.
He had been enrolled for four years, practicing day after day, yet still hadn't touched the threshold of Shikai.
Yoruichi took only seven days to attain Shikai and actually complained it was slow.
'Since when had attaining Shikai become measured in units of 'days'?'
Setsuna nodded slightly. "Your talent with the Zanpakuto is indeed relatively ordinary. Rather than expending too much effort in this area, it's better to specialize in Hakuda and Shunpo."
Yoruichi nodded in agreement. "You're right. I'm actually mainly interested in the Reiatsu Boost from Shikai and Bankai. It's enough to just casually develop the Zanpakuto to the Bankai-level."
Hearing this, Omaeda silently turned around, his shoulders trembling slightly.
'Casually develop to Bankai? Listen, is that human speech?'
As a regular genius surrounded by these three super-geniuses, the pressure on him was simply too great.
After saying this, Yoruichi asked again, "You've already reached the graduation standard for all four disciplines, Zanjutsu, Hakuda, Hoho, Kido, which is equivalent to a sixth-year student, haven't you? Logically, you could apply for graduation now."
Setsuna shook his head slightly. "Still far from it. I've only mastered Kido below #10 so far. I'll consider graduation only after I've mastered all Kido, completed courses like the Soul Burial ceremony, knowledge regarding Hollows, and practical techniques for hunting Hollows. Hmm... it'll take at least a year."
Hearing this, Yoruichi couldn't help but feel speechless. "Even with your talent, wanting to master all Kido within a year is impossible."
She paused, then added, "Of course, the most crucial point is that the academy simply doesn't teach Kido numbered above 60."
"They don't teach them?" Setsuna was somewhat surprised.
Yoruichi couldn't help but complained, "Do you think everyone is as monstrous as you? A Shinigami graduating normally who can master all Kido within #30 is already considered excellent. Most Shinigami, in their entire lifetimes, can only proficiently master a dozen or twenty Kido. Why would they need to consider learning all Kido?"
She walked closer to Setsuna and continued explaining. "Kido above #60 can be considered high-level Kido, requiring extremely strong Reiatsu Control and deep theoretical foundation. Shin'o Academy is only responsible for laying the foundation. Truly high-level Kido are either learned after joining the Gotei 13 or acquired by joining some noble families and receiving their heritage."
At that moment, a clear, bright voice came from the training ground entrance. "Kido requires heritage. Even after joining the Gotei 13, before becoming a Captain, one can at most learn Kido up to #90. For most Shinigami, that is already enough. But for a genius like Setsuna-kun, I'm afraid that might not be sufficient, right?"
Everyone turned to look. A young man wearing a Shihakusho, with an outstanding demeanor, was leaning against the doorframe. The hilt of the Zanpakuto at his waist was wrapped with exquisite cord.
Yoruichi exclaimed in surprise, "It's you? Kuchiki Koga!"
Setsuna had naturally heard this name as well… Kuchiki Clan's head's son-in-law, the genius Shinigami hailed as 'the future of the Kuchiki Clan'.
It was said that even during his time at Shin'o Academy, he was a prominent figure. After joining the Kuchiki Clan for just a few years, he had already displayed astonishing strength.
