Toshi Uzumaki finally decided to bring Ryusuke and his younger siblings, Sirin and Joyce, to his homeland, Uzushiogakure. His instincts told him that these children would bring prosperity and wealth to the island nation. However, he was unaware that Ryusuke would also bring Honkai Energy an chaotic, highly advanced force far beyond this world's understanding.
Honkai was not just energy; it was a cataclysmic force. Its advanced technologies could revolutionize civilization, yet its destructive power could trigger an apocalypse on a scale beyond the world itself if recklessly used it.
Toshi, as the first son of Shinji Uzumaki, the current head of the Uzumaki clan and Daimyō of Uzushiogakure, held significant influence. However, the chaos of the Warring States Period had left the Uzumaki dissatisfied with Butsuma Senju, the leader of the Senju clan. While their two clans were distant relatives and long-time allies, the growing tensions could not be ignored.
─────────── ⋆⋅☆⋅⋆ ──────────
After a month at sea, their ship finally arrived at the port of Uzushiogakure. Sirin and Joyce, filled with excitement, eagerly took in the majestic sights of the village.
"Woah! Big brother, look!" Sirin said cheerfully, pointing at the unique architecture. Unlike the traditional Japanese-style buildings of the mainland, Uzushiogakure featured mid-story structures a design distinct from any other country.
Ryusuke silently observed before glancing at Toshi, who gave him a knowing nod. Together with his younger siblings, Toshi, and the ship's crew, Ryusuke made his way to the Administrative Office of Uzushio, where they would meet Shinji Uzumaki, the ruler of the island nation.
As they stepped into the hall, a deep, authoritative voice rang out. "Toshi, who are these outsiders?" Shinji Uzumaki's sharp gaze locked onto Ryusuke. "Since the founding of our clan, our rule has been clear. No outsiders shall set foot on our land."
Suddenly, an oppressive killing intent filled the room, targeting both Toshi and the three outsiders. Ryusuke, Sirin, and Joyce.
However, before Shinji's aura could fully take effect, the temperature in the room plummeted. Snowflakes began to fall, despite Uzushiogakure's tropical climate.
Shinji's eyes narrowed in confusion. The source? Ryusuke. His glowing bluish-purple eyes with finality's symbol, brimming with immeasurable Honkai Energy, locked onto Shinji with an icy glare. Ryusuke stood firm, shielding his frightened younger siblings from Shinji's intense aura.
Even Shinji, an experienced Kage-level ninja, hardened by years of war, flinched under Ryusuke's presence. "This kid…" Shinji muttered, his sharp gaze scanning Ryusuke.
Despite being only a boy, Ryusuke's tall, muscular frame was clear even through his fishnet shirt, which outlined his dense yet perfectly balanced physique. His strength and agility surpassed even Shinji's own, despite his decades of experience. Realizing the situation was escalating, Toshi stepped forward, attempting to defuse the tension.
"Father, stop." His voice was firm. "Ryusuke may be cold and distant, but that's because of his circumstances. I brought them here, so they are my responsibility. They want to settle in our homeland."
Shinji furrowed his brows, deep in thought. "And what if they are spies?" he challenged. "Or worse what if they are Uchiha's spy, sent to infiltrate our clan?"
"They are survivors of the fallen Hyoudou clan." Toshi answered. Shinji's sharp gaze remained on Ryusuke. "Then tell me, what is your true goal here?"
Ryusuke met his gaze, unshaken. "I want my siblings to live in a peaceful environment." he stated, his cold, cynical tone unwavering. "And I want to establish a new clan." Shinji's eyes narrowed. "You want to rebuild the Hyoudou clan?"
"No that will be foolish," Ryusuke said, shaking his head. "That name is a curse, a stain that would bring nothing but harm to Uzushiogakure and the Uzumaki clan's reputation. The entire ninja world knows that no one associates with the Hyoudou clan, especially after its failure two generations ago."
His gaze hardened. "From this moment onward, I am Ryusuke Kaslana." Toshi and Shinji were stunned. Moments later, both Sirin and Joyce followed suit, renouncing their old surname and adopting the name Kaslana as well. That day, a new name one that would shape history was born in Uzushiogakure. The House of Kaslana had emerged.

After Ryusuke and his siblings settled in Uzushiogakure, his system notified him of a quest completion. He claimed his rewards, 90 pulls for the standard banner and 10 pulls for the limited event banner. Choosing to use all 90 pulls on the standard banner, he eagerly awaited his gacha results. To his delight, he received two 5-star weapons.

'Nice! I got Void Archives, which contains libraries of all the PE technology, and the powerful Star of Eden that can create artificial black holes, even at an atomic level.' he thought with a smile.
"Big brother, why are you smiling? Are you happy?" Joyce asked.
Ryusuke simply nodded. "Yes, because you two are finally safe from the chaos of the Warring States." Although he smiled, he kept the existence of the system secret; some higher power prevented him from revealing the truth to his siblings.
Uzushiogakure has a population of 20,000, 80% civilians and 20% ninjas.
A week later, Ryusuke and his siblings met the entire royal Uzumaki family, the purebloods who rule the Land of Whirlpool. To his surprise, Ryusuke encountered a Uzumaki version of Elysia, the beloved character from one of his favorite games, Honkai Impact 3rd, known as the Herrscher of Humanity.
Elysia Uzumaki is almost a one-to-one replica of her original HI3rd counterpart in personality, eye color, looks, and voice. However, there are key differences. In HI3rd, the original Elysia had pink hair, elf-like pointed ears, and was in her twenties before she died 50,000 years ago. In contrast, her simulated version SIM-Elysia is over 50,000 years old, residing within the Elysian Realm with the other 12 Flame-chaser. She is the bearer of Signet: Ego, second-ranked and co-leader of Flame-chaser and the founder of the 13 Flame-chasers, living in an advanced, Honkai based high-tech era. Born from nothingness, she holds the titles of both the 0th Herrscher the Herrscher of Origin and the 13th Herrscher the Herrscher of Ego.
This version of Elysia, however, is quite different. With her signature red hair, abundant chakra, and the longevity typical of the Uzumaki clan, she is a human ninja and the youngest princess of the Uzumaki clan at just 15 years old. She lives in an era where electricity and modern technology have yet to be invented, as the chaos of the Warring States halted technological progress before the steam era. Tragically, this Elysia bears a dark legacy, having taken hundreds of lives as part of her work, accepting commissions from wealthy nobles and businessmen from distant lands.
"The phrase 'I love you in every universe' carries a profound truth," Ryusuke muttered sadly, his usual cold expression softening as he looked at his younger siblings and Elysia. This was his first meeting with her, and as a True Herrscher, he sensed her inner emotions. Despite her hardened exterior, shaped by a life of hardship and loss, she was, at heart, a good person.
Elysia, trained as a Warring States ninja, had keen senses and clearly heard Ryusuke's words. Yet, she chose to remain silent, pretending not to notice, as her high-profile background forced her to be on high alert around newcomers. Through her Mind Eye Kagura, however, she sensed that Ryusuke's words were genuine, a confusion that stemmed from the fact that she had never known him personally. This was their first meeting after Toshi had introduced Ryusuke and his siblings to her and her older sister, Mito.
Later, Ryusuke was summoned to the Uzushiogakure Administrative Office to present his proposal. He planned to introduce Honkai energy-based technology for power generation, civilian applications, and military uses, while also addressing its pros, cons, risks, and the dangers of reckless misuse. Despite these risks, his proposal promised to boost the Land of Whirlpool's economy, improve logistics, and bring high technological advancements to both military and civilian sectors.
"So here are my plans for Uzushiogakure and the entire Land of Whirlpool to spur development in our economy, military, logistics, and technology." Ryusuke announced as he presented his proposal to the royal family and clan elders of the Uzumaki clan. "First, we establish advanced infrastructure for energy, civilian needs, logistics, and military applications. Second, we create an industrial district for processing raw materials into finished products. Third, we set up a dedicated energy department. Fourth, we develop cutting-edge military technologies, all powered by a single type of energy."
Shinji, the current Uzushiogakure Daimyō and clan head, interjected, "What kind of energy? Are you talking about chakra? These advanced technologies are far too advanced for our era. Even with our chakra and sealing arts, it might take years and enormous resources to develop them." Elysia, Mito, and the other clan elders murmured their agreement. Only Toshi, who already knew about Ryusuke's plan, looked on in contemplative amazement at its complexity.
Ryusuke then dropped a bombshell. "We are not relying on chakra and sealing arts alone." The room fell silent in shock.
One of the Uzumaki elders began, "That level of technology seems impossible to achieve. You just—" but Ryusuke cut him off.
"There is a higher form of energy than chakra or any natural energies, it's called Honkai energy." While everyone else reacted with astonishment, Toshi remained unsurprised. During the sea voyage before arriving in Uzushiogakure, Ryusuke had already explained the pros and risks of Honkai energy to him. Yet even Toshi hadn't expected its potential to be so vast.
Shinji asked, "So, what exactly is this Honkai energy you speak of?" Ryusuke replied coolly:
"Honkai energy offers many possibilities. It can transmute matter and conventional energy by up to 350%, enhance combat capabilities, and power technologies and weapons based on Honkai principles. It is a powerful and efficient energy source. But as its name suggests, 'Honkai' meaning collapse or decay every source of Honkai energy emits dangerous Honkai radiation. This radiation can be lethal to ordinary people lacking Honkai resistance or adaptability genes. At high levels, it can cause plagues, supernatural disasters, the creation of silicone-based monsters, and even spawn a Herrscher. For example, at 10hw (Honkai welt) the energy can reanimate the dead or alive into Honkai zombies, at 100hw it spawns Honkai beasts, and at 2000hw or more it can trigger a catastrophic Honkai Eruption that births a Herrscher, an god-like being that can bend physical laws at will and, worst of all, herald the end of the world."
A heavy silence followed as everyone absorbed the gravity of his words. "Such a dangerous type of energy." Elysia murmured, and the other elders echoed her concern. Only Toshi seemed unfazed. "So, that event is like the one in the Land of Lightning that caused a Honkai eruption, who becomes a Herrscher?" Shinji pressed.
Ryusuke's tone turned even colder yet honest. "I did it. I am the True Herrscher, the Herrscher of Finality, who outclasses all other Herrschers combined. However, during that Honkai Eruption, my younger siblings became Herrschers as well."
The room erupted in shocked murmurs, and several clan members began to ready their weapons and channel their ki against Ryusuke. Before anyone could act rashly, Toshi stepped forward. "Ryusuke and his siblings are good people, despite the circumstances that made them Herrschers. He shared his secrets with me during our voyage before they settled here in Uzushiogakure."
Toshi continued, "It is my decision and responsibility to bring them here. I did not intend to break our rules by admitting outsiders into our midst, traditions, or overestimating our art of sealing because of the protection of the Senju clan. Yes, the use of Honkai energy is risky, but with strict protocols and security measures, it can become our greatest asset. To be honest we only had unparalleled talent for sealing arts but that's only we had. What if the Senju clan changes its interests. Because there are no such things as eternal allies only interests. And interest can be changed."
After a tense moment, the elders, including Shinji, Mito, and Elysia, finally relented. One by one, they signed the scroll. All future projects based on Honkai energy would fall under the joint oversight of Ryusuke Kaslana and Toshi Uzumaki.
Thus, a new chapter began for Uzushiogakure, a future powered by the dangerous yet transformative potential of Honkai energy also the change of saving the Uzushiogakure's ill fated its destruction during the 2nd great ninja war because of over trusting to their ally and besieged by 4 nations.
