Main perspective:
While cosplaying Dazai at a convention, Uesugi Rikuichi is suddenly bound by a little glowing orb claiming to be the System, and forced to transmigrate to another world. With no other choice, he takes on two fake-script-team roles and uses his wits against the real script team, while also saving, like, a bit of the world.
Other people's perspective:
A massive organization is spread across every corner of Japan. Its members are all rare geniuses who roam the world, bringing it light.
P.S. Yes, I just want to poach all of Mori's talented people.
Theme: If there's no one in the world who loves you, loving yourself is great too
