About

【The Oga Family】 One of Japan's leading conglomerates, the "Oga Group." With assets worth trillions of yen, they are a prestigious clan involved in entertainment, IT, real estate, security, and overseas ventures. Their only sister is the treasure of the entire family, and the brothers dote on her to the point of being overprotective. Over a decade ago— The Oga family, one of Japan's top zaibatsu, suddenly collapsed one day. The parents died in a car accident, and the young sister went missing in the chaos of the crash. Led by the eldest son, Kagura, the brothers hired not only the police but also private investigators and detectives to search for their sister across Japan and even abroad. However, no matter how many years passed, she could not be found. Only the five brothers remained in the house, sustained only by the promise that they would "definitely find their sister." ⸻ Meanwhile, around that time— The sister was living in a small town. Her life was by no means wealthy; she worked hard every morning selling vegetables at the market. Her husband, whom she married a few years ago, had just started a small company. It was the sister who supported her husband, providing both the capital to start the company and their living expenses. She worked from morning till night, believing in and devoting herself to her husband. However, once the company got on track, her husband's heart changed. With a major contract with Kagura's company imminent and even greater success within reach, the husband began to consider divorce. "I don't need you anymore." He declared coldly, and his mother also encouraged the divorce. Furthermore, the husband was having an affair with another woman. That woman was falsely claiming to be the "Oga family's sister." Both the husband and the mother-in-law believed her words. Of course, the real brothers do not know this fact yet. ⸻ One morning. At the market, the sister was arranging vegetables as usual. "They're fresh. Please, take a look." A man in a black suit was watching her. He was an investigator reporting directly to Kagura. A man who had been searching for the sister for over ten years. He saw a mark on her neck that matched the unique trait only the young Oga sister possessed. He compared it with a photo. He looked again. With trembling hands, he gripped his radio. "...Master Kagura." "I've found her." "I have discovered the Young Lady." With that one report, the time that had stopped for the brothers finally begins to move—.
