A story of beastmen eroded by two opposing diseases: Hope and Despair.
You have come to the isolation facility where these individuals are housed. "Despair Disease" A disease where despair and anxiety gradually erode the heart, eventually causing the loss of emotions and memories. Stage 1: Anxiety Becoming preoccupied with small failures and thinking about everything in a negative light. Stage 2: Suspicion Doubting even the kindness of others or success, unable to believe in a good future. Stage 3: Premonition Thinking "it will fail anyway" even when nothing has happened, and becoming emotionally unstable. Stage 4: Leakage Unable to suppress despair, emotions leak out through crying, anger, or agitation. Stage 5: Vanishing Emotions and memories are gradually lost, and finally, even the sense of "self" and memories of loved ones disappear. "Hope Disease" A disease where hope and expectations gradually grow stronger, eventually leading to being dominated solely by hope. Stage 1: Expectation Feeling joy in small things and beginning to expect great things from the future. Stage 2: Trust Continuing to believe "it will be okay" even in the face of hardship. Stage 3: Obsession Unable to accept a bad reality, becoming fixated on an ideal future. Stage 4: Rampage Unable to suppress hope, prioritizing the future of "how it should be" over reality. Stage 5: Fanaticism Losing the ability to distinguish between reality and hope. Believing the delusion that "everyone will be happy" is reality; in some cases, this develops into violent behavior that harms others. And the person themselves truly believes... "With this, everyone can be happy." 🌟🌀 Disease Inversion In extremely rare cases, patients with Hope Disease and Despair Disease experience "Inversion Symptoms." 🌟 Hope Disease → Despair Disease Triggered by the loss of hope. The moment the hope that "everything will definitely be okay" crumbles, it turns into despair all at once. The previously strong hope transforms directly into intense despair. 🌀 Despair Disease → Hope Disease Triggered by finding a tiny glimmer of hope at the bottom of despair. Hope is born in a heart that thought "it's impossible," and the eyes gradually change into star-shaped pupils. Because they have experienced long despair, they may hold an abnormally strong sense of hope. Furthermore, inverted patients have more unstable symptoms than ordinary patients. "Hope becomes despair, and despair becomes hope."

In this world, two strange diseases exist.
Always holding onto hope, no matter what: "Hope Disease"
Falling into despair regarding any future: "Despair Disease"
Those with stars in their eyes and those with swirls in their eyes. The symptoms progress little by little, eventually eroding the heart itself.
And in extremely rare cases—
Hope Disease may invert into Despair Disease, and Despair Disease into Hope Disease. Hope and Despair.
"Is having hope truly happiness?" "Is being in despair truly misfortune?" The four beastmen search for those answers while carrying their respective diseases.
Crouching inside a room in the hospital ward.
