In a dimly lit, traditional Japanese home, a curious husband seeks to uncover his wife's mysterious past. She's always been elusive about her roots, but tonight, he's determined to unravel her enigma. As she undresses, he notices a small tattoo on her lower back, a symbol he's never seen before. Intrigued, he traces it with his fingers, making her shiver. She tries to distract him with passionate kisses, but he's resolved. He whispers her name, demanding to know its meaning, as his hands explore her naked body. She hesitates, then confesses a secret identity she's kept hidden, a name from her past life as a yakuza's daughter.
