It had been nine long years since Yami Hozuki had last been seen, and in that time, he had grown into a formidable force to be reckoned with. At just 15 years old, he had already earned the title of the youngest swordsman and the Raging Water Storm of the Mist, serving as the third Mizukage's right-hand man. Together, they had worked tirelessly to improve Kirigakure's economy, implementing a ninja ranking system and forming three ninja squads to bolster the village's forces. Additionally, Yami had taken on the leadership of the Mūn, a sub-division founded by Saizō Terumī, the Mizukage's younger brother, to control mob wars within Kirigakure.
Over the years, Yami's demon eyes abilities had evolved, granting him heightened perception that made others' movements seem slow in comparison. He could now see the water within people's bodies within a one-mile radius, giving him a unique advantage in battle. His newfound powers included the ability to unleash a sky-blue ice freezing technique akin to Susanoo, as well as a frost flame so cold that it burned and an Ice Age technique that could freeze everything within a three-mile radius. His arsenal of jutsu had also expanded, encompassing a wide range of water, wind, fire, lightning, and earth techniques, as well as clan techniques and kekkei genkai moves.
Inside the Mizukage's office, Yami stood before the Sandaime Mizukage, a tall and imposing figure with black sclerae and long black hair. The Mizukage informed Yami of their plan to seal the Three-Tails into a Leaf Village shinobi, but Yami expressed his reservations, believing they should focus on monitoring the Kaguya Clan's movements. Despite his concerns, the Mizukage insisted on carrying out the sealing, revealing a sense of complacency that concerned Yami deeply.
As events unfolded near the Kannabi Bridge, Yami utilized his Hydrification technique to conceal himself and observe from the shadows. He witnessed the harrowing events that transpired, including the kidnapping of Rin by enemy shinobi and the subsequent rescue mission led by Kakashi and Obito. Tragically, Rin was forced to implant Obito's Sharingan into Kakashi's eye socket before sacrificing herself to protect the village, choosing to impale herself on Kakashi's Chidori rather than risk Konoha's safety. Her selfless act left both Kakashi and Obito devastated, with Rin's dying words echoing in their ears as she passed away.
Yami watched in silence, his heart heavy with the weight of loss and sacrifice. The memory of his fallen friend, Soma, intertwined with Rin's tragic fate, fueling his resolve to protect those he cared for at all costs. As he prepared to embark on his next mission, the shadows of the past loomed large, reminding him of the harsh realities of the ninja world and the sacrifices required to navigate its treacherous waters. With Hiramekarei in hand and his demon eyes ablaze, Yami set out to fulfill his duty as the Raging Water Storm of the Mist, a beacon of hope in the midst of darkness.
