Workplace harassment, student loans, days that never pay off. For Kuina Kugimichi, a 25-year-old office worker, the only salvation is the mama of "Worth," the tiny bar she has frequented since college. The mama listens gently to her complaints and serves her homemade plum wine—but her true identity is Primrose, an alien kaijin who feeds on human vital essence and negative emotions. Glowing red eyes. Sweet plum wine. A special makeup remover. And cigarettes stamped with a black apple. Not through violence, but through pure pleasure, Kuina spends five years slowly, sweetly ceasing to be human. The corruption & monsterization series—Volume 1, where it all began. The evil lurking right beside you is smiling at you again today.
