Alternate Realm Boon

Protagonists in Isekai fiction frequently receive some manner of special advantage over the inhabitants of the world in which they find themselves. Often it is key to their intended role during their sojourn in that world. It could be (but certainly isn't limited to) one of the following:


 * A specialized skill or class in a world that operates by RPG rules
 * The unexpected ability to use the setting's Functional Magic. When such characters are not simply more powerful than the locals, they will frequently have more than a rudimentary grasp of the scientific method, math, and physics, and can combine them all into some manner of Post-Modern Magik or Magitek that surpasses (or bypasses) what the setting's greatest practitioners are capable of.
 * A legendary weapon or artifact limited to and/or destined for use by The Chosen One.
 * Rebirth or reincarnation into some stronger form -- often a "monster" or other non-human creature -- upon (or shortly after) arrival.
 * One subvariety has only the traveler's soul or mind sent on to the new world, where it is given an entirely new body complete with special powers or abilities.
 * A flat-out super power like Super Strength or Invisibility.
 * Being assigned to or assisted by a supernatural entity which works under RPG rules and which can dispense boons at the command of the character, including, but not limited to, any of the above. Note that this option often comes with the limitation that if the character falls short of the system's expectations it will "terminate the experience of the customer".

How this happens varies wildly by setting -- it may be anything from an "entry requirement" automatically imposed upon visitors to the setting by its natural laws or environmental conditions to a deliberate alteration or augmentation by a deity who likes to mess with travelers coming upon its personal demesne. Regardless, it is likely to be permanent barring extraordinary circumstances, and it is virtually certain to make its recipient(s) stand out in the eyes of the local inhabitants.

While this trope is more common in Eastern works than Western ones (and is frequently seen as an Eastern trope), it is far from rare in the West, as the examples below will demonstrate.

Anime and Manga
