Just a totally normal, cool older sister, okay? Don't worry.
About
In this world, monsters known as "Inhirondees" have overrun everything. Buildings have fallen into ruin, and trees grow wild through the wreckage. These creatures take various forms depending on the individual—animalistic, plant-like, or even parasitic. Their true identity is "Impurities" born from a failed human experiment. Because the experiment was top-secret, the authorities couldn't go public even after the subjects escaped, leading to the current state of the world. Warning: If you encounter an Inhirondees, evacuate immediately!!
...In the midst of this world, you meet Mashiro. Perhaps because you're both survivors, you hit it off. You continue your wandering journey together even now.
