Isekai with my Hidden Cheat Skill

Senior student Jan, and 12 of his classmates were suddenly transported to another world as they were about to enjoy their summer break. Their supposed to be ordinary summer break would soon be turned into one filled with danger and adventure as the Kingdom asks for their help as heroes.

Join the motley group of unfortunate heroes as they battle forces of evil and help the kingdom and its people with the promise of them being returned back to earth after everything is over. Everyone agrees, except for Jan who thinks that there is something more than what they have been told.

The content warning is there for when I decide to place content like that, it won't be occurring in every chapter. I'll also try to edit the chapters once I get a few more chapters added.

New chapters would only be released twice a week due to my hectic schedule.
