The Whole Class Got Isekai'd In An Uninhabited Island In Another World

I’m Shinomiya Hokage, a 3rd-year high-school boy who dreams of a survival life. One day, everyone in my school transferred to a mysterious island in a parallel world. I woke up in an unknown cave and I started moving on my own. Then, I met up with some of my classmates. My knowledge and tools in survival shines through. I was a plain guy in school but I’m the leader in this world. ■□■　It’s a story where they make earthenware and stone tools　■□■ There’s no development where they get unique adventurer skills. I don't own the novel or the image, and there will be R18 here and is just a repost and I don't own it The Novels Full Name Is EASY SURVIVAL LIFE IN THE OTHER WORLD ~EVERYONE IN SCHOOL TRANSFERRED TO AN UNINHABITED ISLAND IN THE OTHER WORLD BUT IT’S AN EASY VICTORY FOR ME~
