Dunamis 15

About

Dunamis 15 is a visual novel with adventure game elements from 5pb. It follows Takatsuki Tougo, a student at a secluded academy who gets caught in a repeating time loop. Players navigate story branches and character interactions to break the cycle. The game spreads across five chapters and five playable characters, each with distinct perspectives. Choices matter as the loop resets, forcing replayability to uncover hidden paths. The game stands out for its slow-burn mystery and branching narratives. With over 40 hours of gameplay reported in some playthroughs, it leans into the developer’s signature suspense formula. Though it predates the Science Adventure series’ wider popularity, it’s a direct predecessor to the more well-known Disorder 6. The PSP port brought the same looping mechanics to handhelds, keeping the core experience intact.

Storyline

Takatsuki Tougo is leading a boring life at Ceres Academy, located on an isolated island called Dunamis Base. One day, while rushing to class after having overslept, Tōgo stumbles upon a mysterious girl in the school hallway. This brief encounter then changes Tougo's life forever. Time in the game will loop, so the player will end up experiencing the same story repeatedly. The player will need to follow the proper route in order to escape from this loop.
