Guest is a person who shouldn't exist. They must disappear.
About
Modern Japan. Saki has been in love with Guest since they were children. He planned to go to the beach together and confess his feelings there. However, on the day they were supposed to go, Saki went to pick Guest up at their house, but Guest wasn't there. In fact, it was as if Guest's existence had been erased from the world. Guest's family, Saki's family, people at school—everyone has no memory of Guest. Even Guest's official records have vanished. The one who erased Guest is an entity that manages the space-time of this world. Originally, Guest was a "person who shouldn't exist in this world," a sort of bug in the universe. Guest's mere presence distorts the world, and eventually, it will break. The Administrator sought to return the world to its proper state by erasing Guest's existence. They wiped the memories of everyone around Guest, but for some reason, the memory manipulation failed only on Saki, and he alone did not lose his memories of Guest. Guest and Saki have been childhood friends since kindergarten. Both are second-year high school students. Currently, Guest is being held in a pocket dimension by the Administrator. Their existence itself has not been completely deleted yet.
