Raging Loop (レイジングループ) is a visual novel that was developed between Kemco and Dwango that tells a narrative that is based off the social deduction game known as Werewolf. The title was written by Shuhei Nobuki, known under the alias "amphibian", and was initially released in Japan for mobile devices on December 3, 2015. Later on the game was ported as a digital title for the PlayStation Vita in 2017, which added full voice acting when the mobile versions were only partially voiced, followed by ports for the PlayStation 4, Nintendo Switch and PC the same year. Eventually PQube published an English version of Raging Loop in 2019 for the PS4, Switch and PC, which was localized by Lemnisca LLC.
The story follows the plight of a group of villagers who are trapped by a mysterious mist in their remote mountain home. Through seemingly supernatural means, a number of people have become "wolves" that will kill one of the villagers each night unless the group participates in a game known as the "Feast" to expose the wolves' identities. At the same time, an outsider named Haruaki Fusaishi, the story's protagonist, has gotten himself mixed up in the village's game after crashing his motorcycle in the mountains. Fusaishi also discovers that he loops back in time to the period right before the Feast begins whenever he is killed, retaining all of his memories in the process. Unable to escape the village or break the never-ending loop, Fusaishi is forced to use his newfound ability to win the game and find out the greater truth behind the Feast.
Raging Loop is an interactive visual novel that contains a branching narrative where the player can obtain a number of endings based on choices made throughout the game. Most of the experience simply involves reading text but occasionally the player will be presented with choices that will branch the story. However, certain choices are locked and cannot be selected or even seen unless the player has the required number of keys. Some times when the player obtains a bad ending and Fusaishi is killed, they will learn something new about the story's overall mystery which is represented by a numbered key. Once the player has gotten certain keys they can travel back in time using the game's flow chart and unlock different choices that will advance the story. The objective of the game is to find the most optimal path through the story and hopefully end the Feast.
