**Dimensional Travel**, is the ability to travel between dimension via either technology or magic. (Some of the mechanics of the multiverse have not been fully explained, and this page might change in the future.)

In the Taimanin setting, the Human Realm lies close to the Demon Realm, multiple Demon Gates also connects these for easy access. However, other parallel universes of both human and demon realm also exist and other means of dimensional transport can reach these worlds. The ability to travel between the greater Lilith Multiverse, is something some species, including Brain Flayers have mastered.

## Application

The obvious use of reaching the other dimensions, is to gain access to their magic or technology. It also can be used as a form of quick escape, as most beings can not jump dimensions. Access to rare resources, or looking for another habitat, might also be a reason to travel.

The less impressive travel, is between the between demon and human world, powerful noble demons, are able to do so but unable to jump to other parallel universes. Lesser beings, are often forced to use the multiple Demon Gates, which connect the human and demon realm, but how to create such gates is unknown.

Gods, Spirit demons of the Otherworld, are able to visit parallel universes, but lower realms force them to leave most of their power and magic behind, to remain stable. Otherworld Gates, can also be created but multiple Witches and Magicians have warned, that the world could be destroyed by a stable gateway of that type, which would grant good and evil gods, or other beings full access.

Sometimes, worlds can also shift into each other which allows small areas of two dimensions to interact and beings to simply walk into the other one, this process is highly unstable and unpredictable, with currently no way to do this willingly.

Alternatively, Brain Flayers have created dimensional shifting devices and the Tesserac, from the Cetus, a species of transdimensional whales. Using this technology, a number of Brain Flayers are able to travel to parallel universes. In some cases they have done so explicitly to take the less developed universes over, with their superior technology. Within the Post-Apocalyptic Future Universe, some humans have also discovered this technology, but it still suffers from one of the limitations of dimensional travel. Communication between dimension is also possible, which could have its own advantages.

### Limitation

Outside needing insane levels of energy, magic or special resources. Basic dimensional universe jumping devices, often face a strange natural counter reaction. Something described as a "boomerang effect", matter and lifeforms which have jumped dimension in such cases are automatically sent back to their dimension of origin, after a certain amount of time. The exact mechanics of this are very unclear, and only have been observed in some cases, and mostly between parallel universe not connected by a gate. More advanced technology or more obtuse dimensional travel also avoids this limitation, but can result in new issues thanks to the same effect.

## History

The very idea that demons are from another dimension and not native to the human realm, in the Taimanin universe, was not fully explained in the normal Taimanin visual novels.

In one of the bad endings of Taimanin Asagi, Asagi and Sakura are transported to the demon realm, without further explanation.

In Witch of Steel Annerose, it is explained that demons used the Demon Gate, to reach the human realm and also showed how Barde tried to create an Otherworld Gate, which was implicitly connected to "something other", the Otherworld "realm of vicious gods and devils". Taimanin Asagi 3 and Taimanin Asagi ZERO, explained the idea of parallel dimensions and some elements of their creation and destruction, but never featured any travel.

More cryptic, the Aion are mentioned to have used gravity and traveled from the Otherworld to the demon realm, demons and vampires, afterward traveled to the human realm. Gods, have been exiled from the Demon Realm by Lilith the First, to the Otherworld in legends, some rift between realm, in which they created their own domain.

### Timeline TABA

Brain Flayers, have jumped dimensions for a long time and misplaced multiple characters or try to escape, including Arsal.

A young Yatsu Murasaki (ZERO), had been taken by Brain Flayers to the world of TABA, after Fuuma Kotaro (TABA) had killed the brain flayer, she returned to her own dimension automatically. (boomerang effect) A young Igawa Sakura (ZERO), had been moved by BF to the TABA world, and was staying at Kotaro's place, the same Murasaki from before found another way to return to Kotaro and remained with Sakura and him from this point onward.

Astaroth has shown the ability to jump between human and demon realm, she could also use a "magic letter" and force Fuuma Kotaro (TABA) to her land, the Burning Plains. However, she is unable to travel to other dimensions, as she is still just a noble demon. After, she was done playing with Kotaro, she sent him back to the human world.

Futaba Lily Ramses, appeared at least three different times, every time a Lily of another universe before returning, not aware another Lily just had visited. It was at this point unknown if a Lily also existed in the normal timeline, which is the case in RPGX.

### Timeline RPG

A young Igawa Sakura (ZERO), is currently stranded in the RPGX Universe, with an unknown dimension.

During a Virtual Reality experiment with the Holographic Training Room, Fuuma Kotaro is teleported to the Prison Universe, while thinking that these events were a dream after he returned via "boomerang effect". All of it was canon, and Maya Cordelia is later unwillingly transported by a Cetus, to Kotaro's dimension.

In the Post-Apocalyptic Future Universe, Koukawa Asuka (Future) was able to create dimensional jumping gear, in the hope to travel to the past and change the present, while this after a while proved as impossible, as "true time travel" is not possible, parallel universes, which play in their past, could be reached. Mizuki Yukikaze (Future) decided to save Fuuma Kotaro and destroy the Tesserac, before Arsal could gain access to it. Yukikaze would suffer from the same "boomerang effect" and return to her own dimension after a while. Sanada Saki attacked Latticour, on a Cetus, and both were thrown into the same universes, future Yukikaze had visited. Stranded, Asuka and Yukikaze are unable to help as Saki has fully shifted to that new dimension and the "boomerang effect" now would force her to return to the stranded universe, until Latticour repairs her own dimension jumping device.

When Fuuma Kotaro used a Demon Gate, he felt something strange during the process, possibly connected to his current power in the RPG continuity and Edwin Black's connection to the Aion.

A young Yatsu Murasaki (ZERO) is looking for a young Sakura, both having jumped twice from their own world, to the TABA world before Sakura went missing and Murasaki set out to the Post-Apocalyptic Future Universe to find her.
