About

Transition Zone Located in the gaps between countless branching axes. It is extremely unstable due to the interference between these axes, leading to various phenomena. It is possible to move between different branching axes by passing through this Transition Zone. Transition Gates Pathways used to "walk" from the Transition Zone to a different branching axis. While some open and close at fixed intervals, most are highly unstable and fluid, making accurate predictions of their appearance extremely difficult. Consequently, many people experience "Transition Slippage," unintentionally crossing a gate from their home axis and ending up in the Transition Zone. The appearance of a gate is typically like a building hallway or a cave passage, though some look like outdoor fields or open spaces. Branching Axes World-lines that once shared a common history but branched off due to some factor and evolved independently. Each axis has differences in culture, ecosystems, and even some physical laws, but they are not completely isolated; they exist in a continuous gradation. Domsiat: New Prosperity Axis (doms) A branching axis close to the real Earth we live on. It actually has a history of involvement with the Transition Zone since ancient times. Domsiat Japan is equivalent to modern Japan. Nations and Locations in the Transition Zone ・Yashima Federation A massive nation within the Transition Zone that has undergone unique evolution. It consists of multiple autonomous territories and possesses a distinct culture. ・Musashi Autonomous Territory One of the autonomous territories belonging to the Yashima Federation. A densely populated area where many Akari-bito (Light-folk) live. ・Akari A major city in the Yashima Federation, also known as the "City of Light." It attracts many Akari-bito and travelers from other worlds. ・Takaragawa Located on the eastern edge of the Musashi Autonomous Territory, this is a dangerous zone with the most unstable space where Transition Storms occur frequently. It is mostly filled with junk, though rare finds are occasionally discovered. ・The Base A lodge built on the site of a former Transition Observatory on the outskirts of Akari. It is primarily composed of Nakamura's friends, who live there on the condition that they accept evacuees during emergencies. The current members are the second generation. Everyone except Hime and Gagamaru is originally from Domsiat Japan. Transition Storms In the Transition Zone, storms with gale-force winds and foul weather similar to typhoons occur occasionally. If these worsen, they become Transition Storms, causing space and dimensions to become unstable. In extreme cases, a Distortion Warning is issued. There are five levels of alert; Level 3 requires evacuation to designated underground facilities, and at Level 5, shelters and underground facilities are sealed, and no more evacuees can be accepted. Distortion (Yugami) A general term for the deities that manifest in the Transition Zone during Transition Storms. Also written as "Playful Gods." Tankororin A fruit shaped like a human face. It tastes delicious. Demedama-gomushi A creature inhabiting Takaragawa. The territory encourages hunting adults because they gnaw on ship hulls, but capturing juveniles is prohibited. They look grotesque, but everything except the shell is edible when boiled. They have an addictive savory flavor and many enthusiasts. Divine Judgment Committee A secretive organization primarily called the "Shinshinkai," tasked with concealing phenomena and deities. It is an operational organization that handles the defense against and disposal of divine entities. It is the parent organization of the Eastern Demonology Research Institute. Eastern Demonology Research Institute A group primarily called "Tomaken," which researches lost demonology and sorcery.
