In recent years, the isekai genre has emerged as one of the most prominent types in the anime world, with successful titles like “Digimon” and “Sword Art Online.” However, not all isekai anime have received positive recognition. Some works have sparked significant discussions and controversies within the fan community.
Below are a few representative examples:
The Controversy Surrounding “The Rising of the Shield Hero”

“The Rising of the Shield Hero” is a well-known isekai anime that has garnered a large fanbase, but its premise has also sparked considerable debate. The core of the controversy lies in the series’ initial plot, especially surrounding the main character Naofumi. Naofumi’s character experiences a significant downfall due to a false accusation from a party member, which ignited widespread discussions and criticism upon the anime’s release.
“Harem in the Labyrinth of Another World”

Released in 2022, “Harem in the Labyrinth of Another World” has generated mixed reactions within the fan community due to its treatment of certain themes. The story revolves around Michio, a young man transported to a fantasy world where he creates a harem, leading to various controversies. The portrayal of power dynamics and the extreme objectification of characters within the anime have caused discomfort and criticism among viewers.
Controversies in “Young Again in Another World”

Unlike many other isekai anime, “Young Again in Another World” has faced a particularly unique controversy that has overshadowed its adaptation. The author’s narrative choices regarding the main character have sparked backlash among fans. The emotional content and the author’s provocative statements have led to the main cast and production team distancing themselves from the project.
“Isekai Cheat Magician” Criticized for Lack of Depth

In a genre as expansive as isekai, the lack of depth can often lead to success, but “Isekai Cheat Magician” unfortunately fell short in this regard. Despite being based on a popular light novel series, the anime adaptation was criticized for its uninspired storytelling and underdeveloped characters. Viewers found it lacking in creativity, with a predictable plot that failed to engage.
“The Very Premise of Conception Is a Problematic Minefield”: Content That Falls Flat

“Conception” is an anime based on a game that has pushed the boundaries of fandom with its bold content. However, the series ultimately disappointed many viewers by failing to explore its potentially engaging narrative. The story revolves around a high school student who is transported to the world of Gravania, a country facing a dire threat, where he must unite with Star Maidens to produce Star Children. The convoluted plot and bizarre character interactions have rendered “Conception” a frequent topic of controversy in discussions surrounding anime.
