Three major isekai anime—That Time I Got Reincarnated as a Slime, Mushoku Tensei: Jobless Reincarnation, and Re:Zero—are streaming simultaneously as of August 12, 2026. Re:Zero's fourth season second cour began on Crunchyroll that day.

The surge marks a return to a densely scheduled period reminiscent of the early 2000s when multiple popular series aired concurrently.

Re:Zero's second cour follows Subaru, who has lost his memories and is searching for a cure for the curse affecting Rem and Julius while exploring the Pleiades Watchtower. Episode 11 resolved a traumatic arc, and episode 12 shows Subaru awakening after his Return by Death ability triggers; Meili, seeking vengeance for her mentor Elsa, had pushed him from a staircase before being forgiven by the group.

Season 4 of Re:Zero returns to a formula that emphasizes trial-based storytelling and repeated cycles of death and rebirth, a method the series used in earlier seasons.

Mushoku Tensei season 3, which aired two strong opening episodes, has slowed since episode 3. Episodes 3 through 7 focus on Rudeus's domestic life, including his family, his sister, and his mother's recovery, with minimal action.

The series has hinted at upcoming danger in the Chaos Breaker arc, as shown in a released trailer.

Reincarnated as a Slime, which split its fourth season into five cours covering roughly 15 months, has maintained a steady pace. The first 11 episodes adapted the tenth light novel, and six additional episodes covered most of the eleventh novel without pacing issues.

Fans have noted that Slime balances slice-of-life moments with political intrigue and fantasy action, while Re:Zero and Mushoku Tensei have been criticized for slower setup.

While Re:Zero and Mushoku Tensei may accelerate their storylines, Slime continues to dominate the current anime schedule.
