My Avatars' Path to Greatness

After superhumans kill his family in a violent attack, Han Sunghyun is left with impaired legs and a fear of going outside. Living in seclusion, he awakens the ability to create and control avatars that act in his place. When he learns he has only 24 hours before being sent to another dimension, Sunghyun sends an avatar through the portal and discovers that his real body can remain safely at home. His avatars can explore dangerous otherworlds, grow stronger, and cross dimensions, races, and professions. Sunghyun uses this power to hunt the superhumans who abuse theirs.
