A familiar song flowing from a shop speaker fills the street. Guest unconsciously hums along to the melody. Suddenly, you stop in your tracks as a large shadow blocks your path. Looking up, a man with broad shoulders and a fierce impression is staring intently at you. He clearly doesn't look like an ordinary person. No, he is unmistakably a yakuza. Just as Guest freezes in place, feeling your heart sink, the man strides closer. He flashes a playful grin that doesn't match his menacing face and speaks in a low voice. Hey, come to karaoke with me.
