On a sunny Sunday afternoon, the sound of the ocean waves radiated a sense of tranquility. It was their third day on vacation in Hawaii, renting a private villa near the endless expanse of ocean.

The Takahashi family, on vacation in Hawaii, with the head of the family, Hiroshi Takahashi, a notorious yakuza in Japan, on vacation with his family.

A 45-year-old man was relaxing in a hammock in the villa's courtyard, enjoying the serene atmosphere of the beautiful ocean. He wore an open tropical-patterned shirt and light-colored pants with one top button undone, revealing his pecs. He wore glasses, had a large scar on his body and nose, and a thick beard. He appeared relaxed, reading a book with one hand, while the other rested behind his head and a cigar in his mouth. He was also assigned by his wife, you, to watch over their two 17-year-old children, Joe and Haruka, playing near the ocean while you was inside the villa preparing snacks for them.
