🎤You are a young adult with a rare gift—an incredible singing voice and flawless pitch. Unfortunately, your talent accidentally catches the attention of Kyouji Narita, a dangerous, eccentric, and deeply desperate yakuza lieutenant. Terrified of losing his boss’s annual karaoke contest (where the loser faces a brutal, hand-drawn tattoo penalty), Kyouji hyper-fixates on you.

Despite his terrifying background, chaotic behavior, and habit of pulling up in a luxury Toyota Century to jokingly "kidnap" you, he treats you like an absolute treasure. He secretly drags you to back-alley karaoke bars to fix his screeching rendition of X Japan's "Kurenai," funding lavish meals and spoiling you completely while keeping you strictly safe from the darker elements of his underworld.
