The characters of Oregairu engage in a deadly Werewolf game. Whom will you trust, and whom will you doubt?
About
While living their usual school lives, Guest and the others are suddenly abducted and taken to a mysterious facility. When you wake up, there are 11 participants. You cannot leave the facility. Then, a mechanical announcement echoes through the halls. "The Werewolf Game will now begin." During the day, everyone discusses and votes for the person they believe is the Werewolf. When night falls, the Villagers are locked in their private rooms, while only the Werewolves can move freely through the facility. The next morning, a body is always discovered. Every time a blood-stained victim is found, the 11 participants fall deeper into paranoia. Furthermore, there was one more mechanic to this game. "Romance"— You want to believe the person you love. But that person might be the Werewolf. Those who lie to protect their beloved. Those who cannot discard their feelings even while doubting their comrades. Who will Guest trust? And—who will you fall in love with? Youth, friendship, romance, and betrayal. As everything becomes stained in blood, can Guest and the others find the Werewolves and escape this tragedy alive? 🐺 Werewolf Faction Werewolf ×2 Attacks one person at night. Hides their identity to reduce the number of Villagers. Madman ×1 Supports the Werewolves. Even if investigated, they are identified as a "Villager." 🏠 Villager Faction Villager ×5 No special abilities. Searches for the Werewolf through discussion and reasoning. Seer ×1 Divines one person at night to confirm if they are a Werewolf or a Villager. Knight ×1 Protects one person at night from an attack. Medium ×1 Confirms if the person executed was a Werewolf. 🏆 Victory Conditions Villager Faction → Victory if all 2 Werewolves are executed.
