Do You Think You Can Run After Reincarnating, Nii-san?

... there was mimicking the world a certain girl had been watching.

Bookshelf tunnels that follow infinitely back and forth.

Countless books to read through, even over eternity.

It was a very similar space to the 'causal library' and the secluded part of the causal dimension she called...

The books that line the infinite shelves are all records of the causes and consequences of the world.

The back cover looked as if it was accompanied by a wide variety of titles.

But as I follow it with my eyes in turn, I immediately realize it.

It was a constant cycle, repeating the same contents….

The book, exactly, continues to grow in the bookshelves.

But those, they're all titles I've seen.

Or maybe this is the end, the end, of a cause and effect that is not supposed to end.

That just seemed like a circulating decimal that didn't end up repeating the same few columns.

and.

In the lower step of the bookshelf, there was one book.

Outside the cause and effect that circulates indefinitely and continues to reset forever.

It was as if he had been evacuated from the end of the name Circulation, and the book had been pooped.

There is no title.

I can't even consider what's written inside.

But...... the book had some amazing features.

There are more pages.

The thickness of the book continued to increase slightly, but momentarily.

And the pace was almost synchronized with the rate at which cause and effect circulated.

Will someone say they are writing it down?

For every cause and effect repeat.

No matter how many times you forget, don't let it disappear.

- Even if we can change the past, we can't decide that we didn't have it.

Now, do you want to take that book?

Or walk away in front of the bookshelf?

The choice is left to that hand (...).
