In a twisted eroge visual novel, Iroha navigates a world of stitched-together perversion. Her journey begins as she discovers an illicit game, 'Pii's Pieces', hidden in her stepbrother's room. As she plays, she's drawn into a realm where bodies are patched together, creating monstrous, yet strangely alluring, forms. Iroha's lust grows with each level, her pussy dripping as she watches the game's protagonist fuck a creature with a cock for a head. When she finds her brother playing the game, she realizes she's not alone in her depravity. They decide to explore their shared kink, leading to a taboo encounter that blurs the line between game and reality.
