Huh. So the boss man fell down the stairs, got teleported to Abby world, went missing in human world.
The stuff in the early chapters happened.
He ran out onto the street after trying to stab Chika, got hit by isekai truck-kun, and he appeared back in the human world.
Little sister tries to enact revenge on boss man but gets thrown off the stairs and gets sent to Abby world.
So you can just go back and forth by dying?
