Shifting Shadows

Time flowed like an unceasing river, carrying Yami through the currents of his second year at the Shin'o Academy. The elusive perpetrator of the Great Spirit Corridor remained shrouded in mystery, slipping through the fingers of vigilance. Eventually, the heightened alertness subsided, gradually replaced by the rhythm of routine.

Yami discovered his strengths and became skilled in unarmed combat and ho oh. His broken asauchi, the sword he once had, remained hidden away. Instead, he used the zanpakuto he had taken from the mysterious man. Even though it looked different from his old sword, nobody knew it was a stolen weapon. It transformed from a Shikai state to an asauchi-like form after losing its connection with its previous owner.

During his second year, Yami had the chance to choose classes that matched his talents. He focused more on sword fighting and ho-oh and also attended standard courses like math and spiritual control. Due to a shortage of shinigami after a previous war, the lessons became more intense. A particular class for confronting hollows was optional for first-year students but mandatory for fourth-year students and above. Those below the fourth year were given extra courses to learn about hollows and their ways.

Yami's understanding of hollows grew deeper in these classes. Hollows were born from human suffering, transforming into powerful beings like Gillian and Adjuchas. Vasto Lorde, the apex predators of the hollow realm, were rumored to be stronger than most captains. They were a mystery considered to be legends.

Yami also learned about the weaknesses of hollows. Their masks were both a weapon and a vulnerability. Breaking the mask could weaken or defeat a hollow. The hollow hole, a void in their body, was another weak point. Targeting it could give an advantage in battle.

Yami's curiosity was piqued by the Vasto Lorde. He wondered about their true strength and how they compared to shinigami captains. It was also rumored in a realm where water manifested as reiatsu, Vasto Lorde stood as lakes. In contrast, captains were mere ponds, their reiatsu a fraction of these apex entities.

The academy's focus shifted to confronting hollows, and Yami played the role of protecting healers and Kido experts from these menacing creatures.

Days turned into weeks, and Yami found himself constantly imagining battles with the man from the Great Spirit Corridor. No matter how much he practiced, he couldn't defeat the man or figure out his true strength. Yami suspected that the man might be hiding his true power.

In his quest to improve, Yami looked to heroes for inspiration. Bang, a martial arts master, used a defensive technique called Water Stream Rock Smashing Fist. a defensive art unparalleled in its majesty. A cerulean aura enveloped his extremities, mirroring the fluidity of water. It repelled and redirected attacks, doubling its force like a raging river swelling its banks.

Atomic Samurai was a sword master who could precisely cut opponents into countless pieces. Yami wished to learn these skills, as even his lack of reiatsu made it no less challenging to put theory into practice as it did not require any supernatural power.

Yami realized that he could blend into the surroundings because he had no reiatsu. This unique power gave him a sense of invisibility. However, he understood that this power had limits. It was like being an assassin rather than a shinigami who relied on reiatsu.

However, even as Yami marveled at his newfound ability, he acknowledged its limitations. His blending prowess, while potent, could not compare to the awe-inspiring tapestry of shinigami abilities. Records spoke of legendary zanpakuto like the one said to be held by Genryusai Yamamoto, the captain commander of the Gotei 13. Its bankai was rumored to possess the cataclysmic potential to reduce the entire Soul Society to ashes. Yami's power, while intriguing, was dwarfed by such power. Moreover, his encounter with the man from the Great Spirit Corridor lingered as a testament to the imperfection of his newfound ability.

As he ventured into the realm of self-discovery, Yami's thoughts drifted to the enigma that had perplexed him since that encounter—how the man had perceived him despite his blending. It was a question that gnawed at his consciousness, demanding answers. Why had the man detected him when others remained oblivious until he was upon them? Yami's musings propelled him into a realm of introspection, a journey to explore the limits of his unique power.

He questioned his own limits and sought ways to escape more effectively. His first pursuit was swiftness—a skill he recognized as vital for survival. His escape from the man in the Great Spirit Corridor had been far from flawless. Determined to rectify this vulnerability, Yami committed himself to mastering the art of rapid evasion. Hours bled into days as he honed his agility, exploring the synergy of physical finesse and bodily control. Yet, as he delved deeper, he realized that raw speed alone might not suffice.

He embarked on a path of scientific exploration, delving into the intricacies of flashbangs and smoke bombs. Physics and chemistry became his guides, leading him to create spiritual variants of these tools. The concept was simple—disrupt reiatsu flow and distort perception. The clash of energies would yield a momentary disarray, a vital window for escape. Yet, all this to be implemented, needed reiatsu.

As Yami prepared for the upcoming hollow confrontations, he knew his journey was far from over. His arsenal of skills and ideas was expanding, and he was ready to face the challenges that lay ahead. The mysteries of the supernatural world beckoned, and Yami was determined to uncover their secrets.
