A world hopper is referred to those who hop between worlds and reality

World hoppers are often called foreign travelers to the worlds they visit but mostly they tend to keep quiet about there world hopping skills for they probably used to to live a quiet life

The power of a world hopper is a rare power that is not used today as for its been lost to time due to how little it used

But thanks to recent media such as isekai,reincarnation and more its been Making a slow comeback albeit with a different name

Although not many today know how its properly used as for the methods above are normally a one way trip with proper practice you can jump to any world and back with ease

However there are cases where a world will recognize the hopper as a being that shouldn't be in that world thus marking them as an singularity

Those marked as this will have unnatural abilities and powers but before long will be rejected by the world and be sent back to their home worlds

But there only one person that was marked as a singularity but is able to traverse the worlds with ease making them a walking singularity

Regardless of what and how the power to hop between worlds is used today it all depends on the user and how they will use it
