You transmigrated, and ended up in the world of the Grim Reaper Elementary Schooler. Oh, maybe there are some sports anime in the mix too? Of course, that doesn't matter. It's a little dangerous, but you can't die. However, every time you die, you gain another secret identity. All you have to do is witness the end of the Conan storyline and stay firmly on the Black Organization's side.
That's easy, isn't it?

:D
Who... am I?
I want to go home.
