Why That Time I Got Reincarnated as a Slime Leads the Rankings
Based on Fuse’s light novel series, That Time I Got Reincarnated as a Slime follows Satoru Mikami, a corporate worker who dies and is reborn as a slime named Rimuru Tempest in a fantasy world. After gaining extraordinary abilities and befriending powerful monsters, Rimuru sets out to build a nation where humans and monsters can coexist.
The fourth season continues the franchise’s story of political conflicts, expanding alliances and powerful rivals. Its strong position in the streaming rankings also follows the series’ established popularity across anime, manga and light novels. The new season is produced by Eight Bit and began airing in April 2026.
Meanwhile, Mushoku Tensei: Jobless Reincarnation secured third place with 666 points. The series follows Rudeus Greyrat, a man reincarnated into a fantasy world who attempts to make the most of his second life by developing his magical abilities and navigating complicated relationships. Its latest season remains a major contender in the isekai genre, although it trails Tensura in this particular ranking.
Re:Zero − Starting Life in Another World Season 4 finished fifth with 489 points. Its darker fantasy narrative, centered on Subaru Natsuki’s ability to return from death, gives it a different approach to the genre compared with Rimuru’s nation-building adventure.
The results suggest that established isekai franchises continue to attract strong streaming interest in Japan. While the ranking offers a snapshot of Summer 2026 performance rather than a definitive measure of every anime fan’s preferences, That Time I Got Reincarnated as a Slime Season 4 secured a substantial lead over its competitors.
