I Joined the Heroes' Association, but Secretly Raise Monsters!

Roger transmigrates to the world of One-Punch Man.

He was only a C-Class hero, but then he gets the Infinite Control System!

Any monster or hero can be controlled once he levels up!

"Ding! Congratulations, Host, on capturing the S-Class hero Superalloy Darkshine. Would you like to activate his monster transformation ability?"

"Ding! Congratulations, Host, on capturing the Dragon-level monster Elder Centipede. The System is ready to grant it the ability to divide like Black Sperm."

"Ding! Congratulations, Host, on capturing Monster King Orochi. Would you like to absorb his power?"

A few months later,

with the power of the System, Roger has turned One-Punch Man into a training game!

While the other C-Class heroes are still struggling to make ends meet, Roger already commands countless subordinates with godlike strength!

Even the Hero Association has to watch its step around him!

"Heh heh, being the boss feels great."
