October is when the fall slate actually starts, and over the past week the last few premiere dates finally locked. Black Clover's second season has a day. So does the new Sgt. Frog. Ace of Diamond Act II picked its return slot, Junket Bank slipped out of the season entirely, and a cluster of October 3–5 debuts all confirmed inside seventy-two hours. Here is the dated calendar, with where each one streams.
Quick answer
The biggest confirmed fall 2026 anime premiere dates are Black Clover Season 2 on October 3 (Crunchyroll, with a U.S. theatrical preview on September 21), the new Sgt. Frog on October 3, A Tale of the Secret Saint on October 3, Hotel Inhumans Season 2 on October 4, So What's Wrong with Getting Reborn as a Goblin? on October 5, Ace of Diamond Act II Second Season Part 2 on October 11, and Dark Machine: The Animation on October 13. Junket Bank has been delayed out of October with no new date. Per SenpaiRanks, the highest-ranked returning franchise in that list is Ace of Diamond Act II at 7.81 on our Consensus board.
The calendar
October 3 — Black Clover Season 2
The headline slot. WANIMA performs the opening, One or Eight takes the ending, and Crunchyroll is running a U.S. theatrical preview on September 21 ahead of the broadcast debut. The first Black Clover series holds 7.65 on our Consensus board — solid rather than elite, and the second season is the franchise's chance to move that number.
October 3 — Sgt. Frog (Keroro Gunsō☆)
A full revival of the Keroro platoon with a new main cast. This one is pure nostalgia arbitrage and the broadcast date is now firm.
October 3 — A Tale of the Secret Saint
Additional cast landed alongside the date in a new promo video. Isekai-adjacent, single cour, and the kind of title that lives or dies on its first three episodes. If that is your lane, the best isekai anime board is the better map.
October 4 — Hotel Inhumans Season 2
Theme song artists confirmed with the date. The first season is already on our board; the sequel inherits its audience rather than building one.
October 5 — So What's Wrong with Getting Reborn as a Goblin?
10:00 p.m. on Tokyo MX, then BS11, Sun TV and AT-X. Sou performs the opening "Hello," AHUB the ending "Chiisana Bokura."
October 11 — Ace of Diamond Act II Second Season, Part 2
Daisuke Sakuma joins as Shinichiro Saotome. This is the highest-scoring returning series on the October list — Act II holds 7.81 on our Consensus board, and the parent series sits at 7.71. Baseball anime does not get a lot of seasonal attention, which is exactly why it keeps outperforming expectations on our sports anime ranking.
October 13 — Dark Machine: The Animation
Three new cast members announced with the date. Late-slot October debut, so it runs well past the seasonal cutoff.
Delayed out of October — Junket Bank
The premiere has been pushed with no replacement date announced. Do not plan around it.
Broadcast
Most of these run on the Tokyo MX / BS11 / AT-X chain, which means simulcast timing in North America and Europe lands the same day rather than a week later. Crunchyroll has the widest slice of the October slate; a handful of titles are HIDIVE or Netflix exclusives in specific regions. We list every platform per show rather than pushing one — the Ramparts of Ice Season 2 Netflix premiere, the HIDIVE run for Nia Liston, and the Magical Explorer White Fox slot are all on different services, and pretending otherwise helps nobody.
For the live view, our schedule page tracks air times as they update, and what to watch this fall is the curated version of this list.
How to read it
A premiere date is not a quality signal. What the dates do tell you is where studios put their confidence: October 3 is the prestige slot, and putting Black Clover, Sgt. Frog and Secret Saint there on the same day is three different bets on the same premium evening. The October 11–13 arrivals are the ones with something to prove.
Per SenpaiRanks, none of the brand-new October titles have enough votes yet to move off the 6.5 prior — that is the point of a prior. As episodes air and ratings come in, the Consensus and Quality numbers separate, and you can watch a show's two axes drift apart in real time. MyAnimeList shows you one number that only moves one direction. Rate the ones you are watching from each show's page above and you are the reason the board moves. For the finished field, our best fall 2026 anime ranking is where these end up.
