What Is "Isekai Reincarnation"? The Roots of the Genre Lie in "Narou-kei"
"Isekai reincarnation" refers to a story in which the protagonist is reborn into another world (isekai) for some reason.
While stories set in fictional worlds have existed for a long time, the true rise of the genre began in the early 2010s, when a surge of isekai-themed novels appeared on web novel platforms such as "Shousetsuka ni Narou" (Let’s Become a Novelist). These stories are collectively referred to as "Narou-kei," and many hit titles from the site were later adapted into anime, accelerating the boom and solidifying isekai reincarnation as a genre in its own right.
From Accidents to Summoning—Many Paths to Reincarnation!
The causes for reincarnation vary widely. Some of the most common triggers include traffic accidents, death from overwork, or being summoned by another world. These events mark the end of the protagonist’s former life and the beginning of a new one in a completely different world.
What Kind of Worlds Do Characters Reincarnate Into?
While each story features a unique setting, the most popular worlds tend to resemble fantasy RPGs. These often include medieval European-style castles and towns, the presence of magic, and dungeon exploration as key themes. This game-like atmosphere allows readers to feel as if they themselves have become the main character, providing a highly immersive experience.
Overpowered with Cheat Skills? The Special Abilities Given to Isekai Protagonists
Protagonists who are reincarnated into another world are often granted special abilities, or "skills," that help them survive in their new environment. These powers are a central element of the story and play a key role in shaping the narrative.
Modern Knowledge
In some cases, the protagonist uses their pre-reincarnation knowledge from the modern world. By applying science, culture, and common sense that don't exist in the isekai world, they can solve problems, earn the respect of others, and gain an advantage in various situations.

Unique Skills
Many protagonists are given rare "unique skills" that only they can use. These powerful abilities often allow them to defeat enemies or overcome obstacles with ease, placing them in an overpowered, or "muso," state. A key appeal of this type of story is the mystery surrounding the origin of these skills and the hidden clues connected to them.

No Abilities
Some protagonists appear to have no powers at all. However, these stories often follow a pattern where the character eventually awakens a hidden ability that surprises everyone around them. Watching the protagonist grow and evolve is both relatable and inspiring.
