“If I put my life in a notebook, it would end in one page.”

Seal, a young man in prison, had so much spare time.

Closed space, unchanging scenery. Every day he read books inside the prison cell.

A boring life that made him feel like he was going insane.

Then, a newcomer came to his prison cell.

His name was Barha Zetta. 79 years old, male. Occupation―Sealer.

Seal was interested in the job of Barha-Zetta and became his disciple to kill time.

Without knowing that it would bear the fate of the world.
