A fourth season for Toaru Kagaku no Railgun (A Certain Scientific Railgun) was announced at the Dengeki Bunko New Year Super Appreciation Winter Festival Online 2025 on Monday.

Tatsuyuki Nagai (Kidou Senshi Gundam: Tekketsu no Orphans) is returning to direct the fourth season at J.C.Staff. Kiyotaka Haimura (Toaru Kagaku no Accelerator) is once again credited for the original character design.

Voice actresses Rina Satou (Akiba Meido Sensou), Satomi Arai (Re:Zero kara Hajimeru Isekai Seikatsu), Aki Toyosaki (Yuru Camp△), and Kanae Itou (Sword Art Online) are reprising their roles as Mikoto Misaka, Kuroko Shirai, Kazari Uiharu, and Ruiko Saten, respectively.

The first two 24-episode anime seasons aired in Fall 2009 and Spring 2013. Geneon Universal Entertainment (now NBCUniversal Entertainment Japan) released a standalone OVA in October 2010. The Blu-ray and DVD volumes and official visual books also included OVA and special episodes.

The third and latest season, Toaru Kagaku no Railgun T (A Certain Scientific Railgun T), premiered in 25 episodes in Winter 2020 (pictured right). Crunchyroll simulcast the anime with subtitles, while Funimation (now Crunchyroll Dubs) streamed it with an English dub.

The anime series adapts Motoi Fuyukawa's action sci-fi manga, which he began in Dengeki Daioh in February 2007. Kadokawa published the 19th volume last March.

Seven Seas Entertainment licensed the manga in English in July 2010 and published the 19th volume on February 11. Funimation licensed the anime series in North America and released the first season on DVD in April 2013 and on Blu-ray in January 2015. The second season was distributed on DVD between July and August 2014 and on Blu-ray in January 2016. The company also released the third season on two BD and DVD volumes in March and June 2021. Crunchyroll plans to release it on Blu-ray on April 8.

Im so glad this is getting a new season. Man i liiteraly finished Railgun T a couple of minutes ago, yea the watch order is a mess when it comes to this franchise💀. At the start i thought this might be too girly for me or just not my thing, and it was really confusing but im so glad i stuck with it because im now in a postion to say this is peak💀🙏.

Welp ima go onto index season 3 now since thats all i have left to watch, that being said ive heard the 3rd season of index has mixed reviews. I like index a lot too so i hope it hits the same. and ofc once i finish everything that empty feeling will sink back with me once more rip.
Come the new season comes soon!!!

Oh man, every season of Railgun has gotten better. Dunno if it's possible that the 4th season can be the best. Definitely have high hopes it will be good though! Woohoo!

@Softhenic03 the animation of Index 3 was good though but the sad thing is the screen time for Touma was too short.. 😅

Please also do the Index season 4 soon please ❤️🥺

@MahiaErebeaNegi I'm not against that either. I just don't expect it since they've repeatedly ignored side stories so far it'd be weird to add them back in now.

I'm kinda hoping we get another anime filler arc with this season just so we could maybe get a 5th season for the Freshman arc and not have to wait for the manga to make two whole new arcs.

Why filler arc when they could just adapt one of the three Railgun SS LNs instead (Like the one featuring Xochitl and her magic faction)? Lol

Jailbreaker hype. NGL, I'm kinda hoping we get another anime filler arc with this season just so we could maybe get a 5th season for the Freshman arc and not have to wait for the manga to make two whole new arcs.

Please announce NT Anime adaptation someday.

I love Railgun. I love ITEM. I love Accelerator Anime.

But please Index is the main story. Continue the main story. Thanks.

Let's goooooo!
I hope this is gonna be as good as always 😌

@Cruyfford nah

ITEM>>>>>Railgun S,T>>>>Index 1,2,3>>>>>>Railgun>>>>>Accelerator

There are still complaints about Index, even though Railgun is a very mediocre and overrated product, as it is pure yuri with bad fanservice, but who cares, with people with bad taste.

Index>>>>>Railgun

Feb 18, 2025 10:23 PM by Koishi_SS

F this where is Index? JC Staff needs to repent for that poorly produced S3.

Feb 17, 2025 1:59 PM by DREAM-T

Wow! My favourite series getting another season?
Hope Touma can also get his.

Glad it's Railgun and not Index, still did not expect another entry in the Toaru series to get animated.

Maybe its finally time for me to catch up on this extremely anodyne series. The reception of Index III ended up breaking my hype for almost anything related to it though.

Feb 16, 2025 11:58 PM by VyseLegendaire

Its been a few years since s3 I guess although the gap between s2 and s3 is bigger

So is this gonna be just 12 eps or anime original or do they actually have enough content for 24 eps? S3 was kinda....

And honestly I dunno like being very honest kuroko had barely any relevance in the entirety of s3 (for that matter s2) nevermind uiharu or saten

I suppose its gonna be 2026 soon so if its actually 24 eps they might catch up or something

If I recall correctly, the next arc is breaking into prison, females fighting hilarious robots. Shokuhou does not appear if I recall correctly.

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Well as long as its not girls fighting groups of dudes....

If they manage to adapt up to flashback arc, it will be girls fighting girls.
Flat-chested Sbokuhou. XD

Well, Shokuhou plays a huge role in Index NT LNs~

all i can do is pray to Kamisama they adapt that.... as well as more Index, cause i like Index more than Railgun because more female baddies
