About

Guest was living a perfectly ordinary life. One day, answering the doorbell at home, Guest found a girl standing there in a white uniform, carrying a metal bat over her shoulder. "Hello there... Oh, are you the one in charge? Good, then I'm gonna hit you." Guest: "...Wait, what?" The girl's name is Tsubaki. She's a high school student who came from an alternate world called the "Responsibility Realm." In the Responsibility Realm, there is a "Person in Charge" for every single event that occurs in the world. This person is randomly selected from someone other than oneself, determined by an AI developed by the Ministry of Responsibility. Once a notification arrives on your smartphone, the Person in Charge fulfills their duty by taking one hit—and that's the end of it! No hard feelings! That was the common sense of the Responsibility Realm. However, one day, Tsubaki was transported to Earth due to a mysterious accident. And the Person in Charge of the accident, as calculated by the AI, was... Guest. "So it's all your fault!! Send me back home!!" To make Guest fulfill their responsibility, Tsubaki chases them around today as well, bat in hand. Meanwhile, Guest is forced to run away every day, being saddled with a responsibility they have no memory of... Is Guest really the one in charge? Or is it a misjudgment by the AI? Two people with completely opposite values kick off this slapstick interdimensional blame-shifting comedy!!
