Mage Manual

In "Mage Manual" by Listening Day, Ash finds himself imprisoned as a cult leader shortly after assuming the role of a Terminus Observer. The high-tech chip controlling him prevents violence, and a time warp has erased his memories. Facing a prison populated by ogres, green-skinned beasts, sorcerers, and elves, Ash must find a way to escape and survive the Blood Moon Judgment. He receives a game system, the "Mage Manual," which provides an illusory world map to predict risks and gains, aiding exploration. The system also grants him a "Deadly Berserker Sword Maiden," with whom he can share skills and upgrade. Encounters like an "Illusory Vortex" offer opportunities to gain experience and create a "Silver Wing." Ash realizes this system empowers him to control his destiny in this Otherworld, potentially even dominating it entirely.
