In Girls Bravo, Yukinari is a small, bullied high school student whose life has been shaped by fear of girls: after years of abuse from them, even a light touch can leave him covered in hives. When he is suddenly pulled into Seiren, a mystic world invisibly orbiting Earth and populated by far more women than men, the problem becomes impossible to avoid. Every ordinary interaction turns awkward or dangerous, and the social balance of Seiren only magnifies his anxiety.
Alone in this hidden realm, Yukinari has to survive the chaos created by a culture he does not understand and a body that reacts against the very people around him. His one relief is Miharu-chan, a new friend whose touch somehow does not trigger his condition. That rare exception gives him a chance to endure Seiren, even as his unlucky life on Earth and the strange, female-dominated order of this world keep dragging him into unpredictable, uncomfortable situations.
