About

If you saw the title and cover art of this work and thought, "Oh, a BSS story... I love those," and opened this,

I recommend you hit the back button.


This is a world where every single law has collapsed.

Laws of physics? They resigned a long time ago.

Gravity, common sense, and causality no longer exist.

Anything is possible. Anything can happen. And no matter what happens, nobody takes responsibility.

If you take it seriously, you've already lost.

No—

The moment you think seriously, your brain will be destroyed.

Just yesterday, I was eating curry when I was suddenly ambushed by a crawfish.

The bathtub became a gate to another world, and I was warped away. Then I thought, "Actually, never mind," and I came right back.

I was growing carrots in the garden, but I harvested a luxury car instead.

If you walk down the street, a grumpy old man will shoulder-check you and shout, 「Hey, you there!」 「Yes?」 「—It's time to Duel!」

If you arch your back like a bow, an actual arrow flies out.

If you flap your mouth like a goldfish, you turn into a killifish.

The moment you mutter 「That's not fair,」 the whole world screams in unison: 「IT IS FAIR!!」

Commuter passes for the Catbus are sold in town.

You can join Death Games via a monthly subscription.

Some people get into the University of Tokyo just by doing muscle training.

You might get mugged by a baby. 「Hand over the cash, punk.」

And sleep time— 30 minutes is plenty.

A country that didn't exist yesterday will celebrate its 「100th Anniversary」 tomorrow.

It makes no sense.

It makes absolutely no sense.

I feel like I'm going insane...
