This is a sequel-heavy year. Ao Ashi, Blue Box, Mushoku Tensei, Spice & Wolf and Girls und Panzer all have new installments landing in 2026, and the question most fans are actually asking is which continuations earned their return. We ranked the biggest sequels by the SenpaiRanks score their earlier seasons already banked, not by hype, so you can see where each franchise stands before the new episodes drop.
Quick answer
According to SenpaiRanks, the strongest returning anime of 2026 by prior-season score are Spice & Wolf: Merchant Meets the Wise Wolf (original TV run tracked at 8.04), Blue Box (8.01) and Ao Ashi (7.79). Ao Ashi Season 2 premieres October 4, 2026 on NHK-E, Blue Box Season 2 and Mushoku Tensei: Jobless Reincarnation III continue their runs, and Spice & Wolf's second season is confirmed for 2027. All are ranked on SenpaiRanks's dual-axis board (Consensus + Quality) rather than a single number.
How we ranked them
Most of these sequels haven't aired enough episodes to earn a fresh aggregate yet, so we anchored the order on each franchise's prior-season SenpaiRanks score — the honest signal for whether a continuation is worth your time. Where a season is mid-run, we note it. You can always open a show's page and rate it yourself to move its position on the board.
The ranked list
1. Mushoku Tensei: Jobless Reincarnation III — Studio Bind
The isekai benchmark returns for a third season at Studio Bind, continuing Rudeus's journey. SenpaiRanks tracks the franchise in the upper tier of its isekai ranking, and the production values that made the first two seasons stand out are intact. If you're new, start at season one before this one.
2. Spice & Wolf: Merchant Meets the Wise Wolf Season 2 — 2027
The original Spice & Wolf sits at 8.04 on SenpaiRanks, one of the highest marks any economics-driven romance has earned here. The 2024 remake's second season is confirmed for 2027, so Holo and Lawrence's ledger stays open a while longer. We covered the season 2 date and streaming details separately.
3. Blue Box Season 2 — October 2026
Blue Box (Ao no Hako) landed its first season at 8.01 on SenpaiRanks, a rare score for a school romance. The badminton-and-basketball love triangle returns for a second season; full release and where-to-watch details are here.
4. Ao Ashi Season 2 — October 4, 2026
The original Ao Ashi holds 7.79 on SenpaiRanks — near the top of its sports ranking. Season 2 premieres October 4 on NHK-E from TMS Entertainment, with 10-FEET and Ai Higuchi on the theme songs. Ashito's climb through the Esperion youth academy continues.
5. You and I Are Polar Opposites Season 2 — 2026
The Shonen Jump+ romcom's first season tracks in the mid-7s on SenpaiRanks. Season 2 keeps the opposites-attract premise going, and it's an easy watch if you want a lighter counterweight to the heavier sequels on this list.
6. Girls und Panzer das Finale — Part 5
The long-running film series reaches its penultimate chapter. Part 5 hits Japanese theaters October 9, 2026 from Bandai Namco Filmworks, with the third-years' final tournament run against St. Gloriana. One more victory to go.
