Kokushibo Is a Little Split-Personality

Kunikuni Iwakatsu is a corporate drone, because he has to manage a lot of worlds.

And time flows differently in every world.

It nearly drove Kunikuni Iwakatsu insane.

For example:

He tells Yoriichi Tsugikuni in World 12 that he needs to use the bathroom, but actually sneaks off to World 11 to slay demons with Yoriichi Tsugikuni there.

Since time keeps passing in every world, he has to slay demons quickly!

Otherwise, Yoriichi Tsugikuni in World 12 will suspect his brother has fallen into the toilet and go in after him!

Or:

He has just turned into a demon after accepting blood in World 11, and then has to rush straight to World 5 to fight the elderly Yoriichi Tsugikuni of World 5 in their final battle!

The only time he can catch his breath is probably when he returns to the citadel for a snack during the night, while everyone is asleep.

Actually, when you think about it, World 5 is pretty nice. With one fewer Yoriichi around, he doesn't have to worry about mistaking one Yoriichi for another.

But why is the dead Yoriichi Tsugikuni from World 5 following him around like a ghost?!

Bug! This is a bug!

Headquarters! Hurry up and fix this bug!
