I Joined the Hero Association, but Secretly Raise Monsters

Rog transmigrates to the world of One-Punch Man.

He was just a C-Class hero, but then he got an Infinite Control System!

Whether they are monsters or heroes, once he levels up, he gains the ability to control them!

"Ding! Congratulations, Host, you've captured the S-Class hero Superalloy Darkshine. Would you like to activate the monster transformation ability?"

"Ding! Congratulations, Host, you've captured the Dragon-level monster Elder Centipede. The System is ready to grant it the splitting ability of Black Sperm."

"Ding! Congratulations, Host, you've captured Monster King Orochi. Would you like to absorb his power?"

A few months later.

With the power of the System, Rog had turned One-Punch Man into a monster-raising game!

While other C-Class heroes were still struggling to make ends meet, Rog already had countless underlings with power beyond belief!

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

"Heh heh, being the boss feels great."
