Our main character Yuuya Kamigasaki is a seemingly normal high school student, however he is also known to have the tendency to open unlocked doors and drawers. It is no surprise that one day he is told that he will reincarnate into another world as a hero. Don't all RPG heroes open every door, drawer and chest etc to get all the loot? And so the princess from another world tell him he can reincarnate in another world as a hero. Sounds cool right?

However there is a twist and spoilers ahead. (Spoiler is only for until Chapter 3)

What she didn't tell him is that he needs to die; It's reincarnation after all, how can you reincarnate when you are still alive and well on Earth? And so in an epic twist the princess is trying to get him killed to be reborn in another world. As the chaos ensues the demon lord comes over as well, for the purpose of protecting Yuuya Kamigasaki from dying and preventing him from reincarnating. Suddenly the good guys are the bad guys and the bad guys are the good guys.

Oh, there is also a childhood friend involved and a lot of plot.
