A brief description of the manga NTR in Another World ~Sullying My Best Friend’s Women With the Strongest Skill~
Our hero, together with his friend, are transported to the so-called “game” world, in which they have to defeat the Demon King in order to complete the “game” and return home.
Kenji Kinoshita, a friend of our hero, has a super strong “gift” for fast leveling, but our hero is deprived of this, but Naoto has his own “special” gift, with which he will not lag behind.
What is this gift? He is able to subtract the levels of others through sex, and the rest you will see in the NTR in another world.
