Newbie Management

"I want to go home!"
Hero Cage was summoned to another world.
He overcomes all adversity, hardship and succeeds in defeating the Demon King.
For a moment he was glad that he could finally return home,
but when he woke up, everything returned to the first day when he was summoned.
Because he repeated the regression countless times,
he has reached the level of catching the strongest demon in another world with his bare hands.
The conclusion reached by the hero who had not been able to stagnate and rot.
“If I can't do it, let’s make someone else catch the Demon King!”
To return home the Hero starts a Newbie Hero Managment!
