Summary
The isekai brand of anime has opened the gates to a variety of wild fantasy series over the years. The genre has frequently served as a highlight of otherworldly settings and situations.
Typically, an isekai protagonist finds themselves thrown into a brand-new world. While dark fantasy is commonplace when it comes to the new world in question,isekai has provided writers spaceto create all manner of new, wild settings for their protagonists. The fish-out-of-water storytelling can lead to all manner of themes and tones, from horrifying situations to fun, upbeat adventures. Some series, however, manage to walk a tightrope, hitting viewers with harsh, often cynical storytelling whilst also providing a surprisingly strong sense of fun along the way.

Naofumi Iwatani, a high-schooler turned fantasy hero, struggles with life after betrayal in this dramatic series. The princess of the kingdom he serves throws him under the figurative bus with false accusations that derail his life and reputation.

The swashbuckling action and colorful supporting characters lend a sense of fantastical fun to the series.

MyAnimeList: 7.96
This dark piece of fantasy isekaiintroduces viewers to a salaryman who finds himself in a truly bizarre situation. After being murdered by an enraged employee he recently sacked, the unnamed protagonist is reincarnated as a little girl.
As if the situation wasn’t bizarre enough already, the newly named Tanya is also stuck in a violent, alternate World War I timeline. Stuck in a grim loop of death and reincarnation, Tanya’s march into a world of military brutality and bloodshed is equal parts disturbing and darkly amusing. Between its eyebrow-raising narrative and frequent depictions of a murderous, Darwinist kid in the lead role, the series is a distasteful, borderline nihilistic affair that also managesto be action-packed and colorful, providing viewers with an eclectic, one of a kind viewing experience.
