Hell Mode is back for a second season on July 4, 2026, and the show used its latest update to lock in two supporting voices, a new opening theme, and the broadcast slot. Taketora joins as Dverg and Shinichiro Miki plays Theodosir, while the band Romanha Marshmallow handles the OP.
Quick answer
Hell Mode: The Hardcore Gamer 2nd Season premieres July 4, 2026 at 1:00 a.m. JST on Tokyo MX, with MBS, AT-X and BS Nippon Television to follow, and streams on HIDIVE (licensed by Sentai Filmworks). The new season is directed by Masato Tamagawa at Yokohama Animation Lab, with series composition by Daishiro Tanimura and character designs by Kei Tsushima. The opening theme is "○✕△□" by Romanha Marshmallow. It adapts Hamuo's light novel (illustrated serialization on Shosetsuka ni Naro since 2019, published by Earth Star Entertainment). Per SenpaiRanks, Hell Mode lands on the Summer 2026 isekai ranking board, where its position updates live as viewers rate each episode.
The new cast
The headline addition is Shinichiro Miki — a veteran whose voice anchors half a dozen long-running franchises — stepping in as Theodosir. Taketora takes Dverg. They slot into the returning core cast around protagonist Kenichi, the gamer reborn into a world running on the brutal "hell mode" difficulty he chose himself.
Production side
Yokohama Animation Lab returns to produce, with Masato Tamagawa directing, Daishiro Tanimura on series composition, and Kei Tsushima handling character designs. The first season ran 12 episodes in Winter 2026, so the turnaround to a summer second season is quick — usually a sign the production pipeline stayed intact between cours.
When you can watch it
Japan gets it first on Tokyo MX at 1:00 a.m. on July 4, with MBS, AT-X and BS Nippon TV close behind. Internationally, Sentai Filmworks holds the license and HIDIVE streams it with multiple subtitle options. The OP, "○✕△□," comes from Romanha Marshmallow.
Worth a slot?
Hardcore-gamer isekai is a crowded lane, but Hell Mode's hook — a player who deliberately picks the hardest settings and grinds his way to absurd power — gives it a clearer identity than most. A fast second season suggests the first found its audience.
