Magical Explorer, Vol. 1 (light novel‪)‬

OUT OF THE FRIEND ZONE AND INTO THE FIRE! Few titles are more revered among horndogs-(ahem) connoisseurs of Japanese erotic video games-than Magical Explorer. One day, our smut-loving hero wakes up to find he has been reincarnated into the body of the game’s dreamboat protagonist! Or rather, his hapless comic-relief best friend, Kousuke Takioto. But with his unparalleled knowledge of Magical Explorer and Kousuke’s unorthodox abilities (a scarf that doubles as a fist?), our hero vows to turn the game’s unluckiest loser into its mightiest heartthrob. In this world, nothing is out of reach when you’ve got the know-how!
