It's remarkable that the first season of this beloved isekai anime only premiered in January 2026, yet it is already returning with a second season this summer. This is a strong and clear indication of HELL MODE's instant popularity among fans.

Unlike many isekai protagonists who are handed overwhelming power from the start, Allen earns every one of his power-ups through relentless effort, determination, and experience. It's easy to see why fans have become so attached to the series, and Allen's earned growth is certainly a major factor.

While the first season wasn't without its flaws, with the use of CGI being one of the most common criticisms, it still delivered a cozy and enjoyable viewing experience that left many fans eager for Season 2, which premieres on January 10, 2026.

Another overpowered protagonist is joining the isekai genre with the Wind Sage Ephtal's anime debut during the Summer 2026 anime season. Hailing from modern Earth, Ephtal reincarnates not once, but twice, in different worlds in pursuit of the peak of magic power.

While Ephtal's first life ended in failure, his second chance grants him the ultimate advantage: vast knowledge of magic and the power needed to finally achieve his bold ambition.

The Summer 2026 anime season wouldn't be complete without an exiled isekai protagonist who wants to prove his worth above all else. Born into a prestigious lineage of master swordsmen, Elymas is eventually cast out after being labeled a failure due to his Heavy Knight class, which is widely regarded as having low offensive power, limited versatility, and poor growth potential.

What his critics fail to realize is that Elymas is an otherworlder with firsthand knowledge of the VR game world he has been thrown into. With that advantage, he already knows the secrets needed to rise from exile to the top. His journey begins on July 3, 2026, with the debut episode of The Exiled Heavy Knight Knows How to Game the System.
