“Of all things, why did I have to become......a muscular, brainless muscle-head!?”

As Muscular recalled his past life, he realized he had been reincarnated as a character from a game he’d loved in his previous life. However, that character was a brainless muscle-head specialized in physical attacks, an underdog who couldn’t even play a meaningful role in the latter half of the game!?

“I’ve finally made it to the world I love so much......I’m going to enjoy this world to the fullest, no matter what!”

Muscular trained the muscle-brained character with all his might and, using his knowledge of the game, worked his way up from the bottom. He also met his favorite heroine from his past life and began helping her avoid the tragic events that were destined to befall her—. A physical-focused fantasy where everything is settled with fists alone begins!
