World Travelers

World Travelers are a select group of humans who have traveled from one world to another. Notably, the ones who are chosen are usually young adults from Japan.

They are typically transported to the Isekai planet, however different worlds are also the subject to this event.

Methods
There are several ways in which a person can crossover from one world to another.
 * Reincarnated: A person who has died by any means has potential to be reincarnated so long as they have a strong will, though it is more of a rarity. When a person with the potential has died, their dying wish is granted in the form of granting their new body with unique skills that reflect the wish. Normally, a human who is reincarnated returns to a human form that closely resembles their original form, however there has been some instances where they have turned into a monster form.


 * Stray: A Stray is the term referred to a person who has traveled to another world by accident, and was not summoned or reincarnated.This case is completely random, with the chosen person not necessarily being capable of surviving in the target world. As with being random, the person has no guarantee that they will appear in a safe location, nor will they have any guarantee that they will have any unique capabilities.

Trivia
 * Summoned: A person can be specifically summoned if they meet certain requirements. These requirements differ based on the world and the individual.
 * Isekai Summoned: On the Isekai Planet, in order to summon an individual, you must gather a group of at least thirty powerful mages to chant for three days to have at least a 0.03% success rate. These mages then cannot cast the summoning again for 33-88 years. The element of time can be avoided by improperly summoning individuals, but this has an extremely high chance of summoning human children that become overwhelmed with magic. This causes them to either slowly succumb to the overdose of magic, or rage out until they are killed or die.
 * Legendary Weapon Summoned: On the plane where the Legendary Weapons reside, mages can summon Legendary Weapons and their wielders. This is done by preforming a ritual that brings forward a human of Japanese nationality that one of the four Legendary Weapons deems worthy. These individuals can come from parallel universes so long as they meet the requirements of the Weapons.
 * The World Travelers stem from the anime genre known as Isekai.
 * The term World Travelers specifically comes from The Time I Got Reincarnated as a Slime.
