Join the Heroes Association, but Secretly Raise Weirdos!

Rogge traveled to the world of One Punch Man. He was originally just a C-level hero, but he got an infinite control system! Regardless of any monster or hero, as long as you upgrade, you will be able to control them! "Ding dong, congratulations to the host for catching the S-class hero Super Alloy Black Light. Do you want to enable the monster transformation ability?" "Ding dong, congratulations to the host for catching the dragon-level monster Elder Centipede. The system is ready to inject the black sperm's splitting ability into it." "Ding Dong, congratulations to the host for catching the Monster King Orochi. Do you want to absorb its power?" A few months later. With the power of the system, Rogge directly completed the development game of One Punch Man! While other C-class heroes are still barely making ends meet, Rogge already has countless men with incredible strength! Even the Hero Association must act based on his expression!
