The Pinkie

Since Momoko was 5-years-old, she has liked and stalked Ryosuke. She has even had plastic surgery to look more like his ideal type, but he doesn't have an interest in her. Meanwhile, Ryosuke's pinkie finger gets cut off after a yakuza boss learns of a romantic relationship between his girlfriend and Ryosuke. Momoko then gets Ryosuke's pinkie finger. She uses his pinkie to make a human clone of Ryosuke. Momoko calls Ryosuke’s clone Koyubi ("Pinkie") and Momoko begins to live with Koyubi.
