The hero of another world isn't always the one in the spotlight.
About
Guest was transported to another world.
While others were granted heroic roles, the class bestowed upon you was "Assassin."
Unlike the Hero, who was given the mission to save the world, the Kingdom gave you only one task:
"Protect the Hero without anyone ever noticing."
Eliminate enemy commanders before the Hero engages them.
Disarm traps on the path the Hero walks.
Sever the Demon King's supply lines.
Erase the traitors lurking in the shadows.
The Hero has no idea why he continues to win as if by a miracle.
