In a world where vampires exist as a hidden society structured like a beehive, the quiet and kind-hearted boy Ichiro struggles through daily life as the target of relentless bullying by his classmates. His only solace is his deep passion for animals and insects. One evening, after another round of harassment, Ichiro encounters a mysterious girl named Lyco on the school grounds near a chapel. Lyco, who calls herself the Queen Bee, suddenly transforms from a young girl into a grown woman and bites Ichiro on the neck.

The next day, when his bullies corner him as usual, Ichiro discovers that he has awakened to a superhuman power. Lyco is a vampire, and within the vampire hierarchy, she is the Queen Bee, the apex predator of her kind. By biting him, she has transformed Ichiro into her Worker Bee, granting him accelerated healing, enhanced strength, and newfound confidence. Ichiro is thrust into a brutal and secret war among vampire factions, where numerous powerful women aspire to become the next Queen Bee and only one can hold that throne. As a Worker Bee, Ichiro must navigate a dangerous world of shifting allegiances, territorial battles, and the primal struggle for dominance. He faces a central question: will he remain loyal to his Queen and fight to protect her reign, or will he forge his own path and fight for his own survival? Throughout the story, Ichiro contends with rival vampire queens, other Worker Bees, and the escalating violence of a society where power is everything, while his relationship with Lyco deepens and becomes increasingly complex. The series blends romance, horror, and supernatural action, following a bullied boy's transformation into a key player in a war fought by creatures that are part vampire and part hive.
