| I always thought we'd see Index season 4 before Railgun sequel, but yeah, guess third season was too big of a disaster. I doubt we'll caught up with the manga even if this comes out anytime next year, but yeah, really looking forward. The flashback arc specifically. |
 |
| Okay, this is just perfection! Nothing more to add. This made my day! |

| I never expected we'd get another season. Hail Saten!! |

| @EcchiGodMamster If I recall correctly, the next arc is breaking into prison, females fighting hilarious robots. Shokuhou does not appear if I recall correctly. If they manage to adapt up to flashback arc, it will be girls fighting girls. Flat-chested Shokuhou. XD Well, Shokuhou plays a huge role in Index NT LNs~ |

| @Cruyfford You do not need to be much better if the "rival" destroyed everything because of the production intervention. It's like sincerely consider himself a champion if your opponent broke his leg and the match did not take place. @Softhenic03 Given the mess with the third season of the index and rumors about the adaptation of the next LN series, I have vague suspicions that they announced Railgun earlier this time to create more Hype for NT. |

| Nice :) Railgun F (the new title perhaps?) is coming sooner than I thought. Nice to see this spin-off is still been given notice and remained popular all this time. |

| @RobertBobert, haha, you're right. Ok so... Any season of Railgun > 1st or 2nd of Index too ✌ |

| @Cruyfford Sorry dude, but you better find another target for such an obvious bait. |
|
| Wonderful news. I am excited. |
If you enjoyed the time you wasted, then its not a waste of time.  |
 After what happened to Index III, I was fearing that JC Staff wouldn't greenlight Railgun S4 until after Index NT or an Index reboot. Though given that JC Staff seemed to consider Railgun as one of their flagship shows, this announcement was just more of a question of "when?" I suppose. I'm glad that key members of the Railgun production staff are returning as well. |

| 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. |
 |
| Glad it's Railgun and not Index, still did not expect another entry in the Toaru series to get animated. |
| Wow! My favourite series getting another season? Hope Touma can also get his. |
| It's not that I dislike this genre but... to add unnecessary fan services to/in/for heroines and ultimately destroys her character and personality; their purity tarnished because of it, is the only thing I hope to not happen to them. For that sole purity is my fan service. |
| 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 |

 |
| Happy news and I don't even watch anime anymore |
| Peak is finally back, hurrah! |
Bum Bum Dum Dum |
| 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. |
| BANZAI NIPPON. Nippon is the Land of freedom. Nippon is the Land of Peace. Nippon is the Land of Justice and Prosperity. In Nippon, we trust. We love Nippon, we love Anime. Anime love us, Nippon love us. 日本 |
| 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. |

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 |

| @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. |
