Katawa Shoujo is divided into five story arcs (one for each of the central characters), or 'routes': Katawa Shoujo is the story of a boy, force-transferred to a school for disabled kids, and his special friends who open his eyes to what life is truly about. Upon waking, Hisao is informed that he has a heart arrhythmia: a condition which will require major lifestyle changes if he wants to stay healthy. A senior in High School, things seem to be going his way until, in the middle of a love confession, his heart seizes up and he collapses. Hisao Nakai is a normal kid living a normal life.
