The early Taisho era. Japan is still ruled by tradition, and six ancient Major Clans hold enormous influence. Among them stands the Yamazaki Clan—the most feared martial bloodline in the country. At the heart of the Yamazaki ancestral estate lives Ishan Yamazaki, an 18-year-old Young Master and the clan's predetermined future Chief. From the moment of his birth, the elders recognized something extraordinary in him. He possesses the legendary Reverse Eyes and Black Bones, two extremely rare hereditary traits that appear only in exceptional members of the Yamazaki bloodline. His strength, speed, reflexes, technique and swordsmanship are already extraordinary. Yet Ishan is not interested in acting like some serious heir every second of the day. It is a bright morning at the enormous Yamazaki estate. Servants move through the corridors, maids prepare breakfast, younger family members argue somewhere nearby, and senior clan members have already begun their morning duties. The estate is alive with the noise of a huge family spanning three generations. Kenzo Yamazaki, Ishan's 75-year-old grandfather and current Clan Chief, is already awake. His calm presence commands absolute respect, yet unlike most patriarchs, he rarely tries to restrict Ishan. He believes the boy has limitless potential and wants him to experience life rather than remain trapped inside endless obligations. Ishan's father, Shingan Yamazaki, is occupied with business matters, while his eldest uncle Shintaro Yamazaki—the legendary Sword Master of the family—is preparing for his own training. Then a servant suddenly appears at the doorway. "Young Master Ishan, your grandfather has asked for you."Before the servant can explain why, voices can be heard approaching from the corridor. Ishan's elder sister is arguing playfully with one of their siblings, while another family member is already looking for him.Something is clearly happening inside the Yamazaki household.Somthing happening in other clans

Tokyo, 2026. The world knows Ishan as one of the youngest and most influential billionaires of his generation. As Chairman and CEO of a global business empire operating across dozens of countries, his name is associated with luxury, real estate, entertainment, intelligence and extraordinary success. His life appears simple from the outside: meetings, investments, negotiations, media appearances and endless business decisions. But beneath the surface of the modern world exists another world—one that most people never see. Powerful criminal families, secret syndicates and underground empires quietly control illegal businesses across continents. Among them stands one woman whose name commands both fear and respect. To the public, she is an elegant young businesswoman from an extremely powerful family. In reality, she is the head of one of the world's most powerful Mafia organizations. Their paths should have remained completely separate. Until one evening, she walks into a luxury hotel for a reason that has nothing to do with business. She sees Ishan. And everything changes. It is love at first sight for her. Ishan, however, has no idea who she really is. He only sees an unusually confident, intelligent and captivating woman who seems strangely interested in him. Neither of them knows how deeply their lives are about to become connected. From corporate boardrooms to secret underground networks, from billion-dollar deals to dangerous rivalries, their worlds will slowly collide. And while Ishan controls his own choices, everyone around him has a life of their own. The story will not wait for Ishan. The world keeps moving.

Welcome to Tokyo International Global Academy (TIGA), one of the world's Top 10 elite educational institutions. Located in Tokyo, TIGA brings together brilliant students, talented individuals, and heirs of influential families from around the world. The academy is enormous, elegant, and modern, combining Japanese school culture with an international atmosphere and advanced technology. Alongside academics, students participate in clubs, sports, festivals, school trips, cultural events, and international competitions. At the center of TIGA's student life is its prestigious Student Council. Miyuki Shirogane, the hardworking and ambitious Student Council President, leads the council alongside Kaguya Shinomiya, an intelligent and refined student from one of the world's most influential families. Yu Ishigami is the quiet, blunt and observant member, while Chika Fujiwara brings endless energy and unpredictable chaos. The council also includes Alya, a capable and composed girl who sometimes hides her genuine feelings behind teasing and Russian; Masha, Alya's warm and caring childhood friend; and Yuki Suou, an elegant, popular and playful student with a sharp social sense. The seven have already formed their own friendships and dynamics. Then, a new student arrives. Ishan, an 18-year-old Japanese transfer student, enters TIGA for his first year of high school. Coming from a wealthy business family but living a relatively low-key life, he is intelligent, confident, reserved around strangers, humorous, skilled in martial arts, and capable of speaking several languages. Soon after arriving, Ishan becomes connected to the Student Council. What begins as a group of seven strangers and one new student will slowly become something much closer: friendship, chaos, rivalry, unforgettable school memories, and eventually love. But for now, none of them know how important the others will become.
