Summoning Heroic Spirits Through Dimensional Shifts

After a cataclysm, Earth plunged into an apocalyptic crisis. To defend against it, humanity summoned Servants to fight invaders from other dimensions.

But all of this was merely the setting of a novel once written by an author who had transmigrated.

This is a slow-burn story, with few exciting moments at the beginning.

I realized that both of my previous novels had the same problem: they didn't match their titles. They were supposed to be about transformation, but ended up being about summoning. This time, I'm writing about summoning from the start, no transformation gimmicks.

The early part of this book is apocalyptic fiction, while the middle and later parts are an infinite-worlds story. There is no female lead, but you can think of the Servants as a harem.

This novel and its characters are entirely fictional. Any resemblance to real people or events is purely coincidental. Do not imitate.
