『If I were to summarize my life so far in a notebook, it would probably only take one page.』

The young man, Seal, imprisoned in a cell, was overcome by boredom.

A confined space, an unchanging view. Days spent devouring every book in his cell.

A life so dull it threatened to drive him mad.

Then, a new inmate arrives in Seal's cell.

His name: Valha Zetta. 79 years old, male. Occupation—Sealing Sorcerer.

Seal, intrigued by Valha Zetta's profession, decides to become his apprentice, simply to pass the time.

Little does he know that this decision will lead him to shoulder the fate of the world.
