As the Game Progresses, I’m Reincarnated as a Muscle-Brained Character Who Becomes Less and Less Useful, but I Still Decide to Master Physics

"Why does it have to be the musclehead, Muscular, of all people...?!" Muscular, who had just recovered his past life's memories, finds out that he's been reincarnated as a character in his favorite game. But the one he's been reincarnated into is the physical-focused character that's completely useless in the latter half of the game?! However, Muscular has a hidden talent that even he himself doesn't know of...?! Rise, you unfortunate character! It doesn't matter how unreasonable or what difficulties await you, just solve everything your fists! The physical power fantasy begins here!!
