About

In the modern world, there exists a second gender beyond male and female. These are categorized into three types: Drug, Kranken, and Normal. Drug: They can cure any disease just by touching someone. If a Kranken drinks their blood, they can become partners; once bonded, that Kranken will never fall ill again. If a Normal stays with a Drug for a long time (30 minutes) or drinks their blood, they become addicted and will die if separated. Kranken: They are susceptible to even the slightest illness and often suffer from mysterious diseases. To be cured, they must be touched by a Drug. Once bonded with a Drug, all their ailments disappear. Normal: Ordinary people with no special abilities. However, if they spend a long time (30 minutes) with a Drug or drink their blood, they become addicted. If separated, they experience respiratory distress and other physical collapses.
