Episode to be 46 minutes long

The official website for the Blood Blockade Battlefront television anime series announced on Friday that the show's 12th and final episode "Hello,world!" will air on October 3 on MBS from 27:58-28:47 (effectively October 4 from 3:58-4:47 a.m.). The episode itself will be 46 minutes long.

The episode will then air on BS11 on October 7 and on Tokyo MX on October 11. The episode will also stream on GYAO!, Niconico, Bandai Channel, d Anime Store, dTV, Anime Hōdai, U-NEXT, and Anime Pass.

The show's staff will additionally host a "Special Event Kekkai Sensen ~Libra Nihon Shibu Welcome Party~" (Special Event Blood Blockade Battlefront Japan Branch Welcome Party~) event on October 4 at Yomiuri Hall in Tokyo.

The staff members had announced in June that they would delay the final episode until July 4 at 26:28 (July 5 at 2:28 a.m.) on MBS. However, MBS had already scheduled the premiere of the Durarara!!×2 Ten season for the same 26:28 timeslot on July 4. The staff then announced later that month that the episode had been delayed beyond that date. The anime's production committee explained that the staff determined that the final episode cannot air in a 30-minute timeslot, since its required length will be longer than estimated.

Dark Horse Comics, North American publisher of the original manga by Yasuhiro Nightow (Trigun), describes the story:

A breach between Earth and the netherworlds has opened up over the city of New York, trapping New Yorkers and creatures from other dimensions in an impenetrable bubble. They've lived together for years, in a world of crazy crime sci-fi sensibilities. Now someone is threatening to sever the bubble, and a group of stylish superhumans is working to keep it from happening.

Rie Matsumoto ( Kyousogiga , Heartcatch Precure! Hana no Miyako de Fashion Show…Desu ka!? ) is directing the anime at the studio BONES. Kazunao Furuya (live-action Liar Game , Galileo, S -Saigo no Keikan- ) is the scriptwriter, and Toshihiro Kawamoto ( Cowboy Bebop , Wolf's Rain , Golden Boy , Mobile Suit Gundam 0083: Stardust Memory ) designed the characters. Shinji Kimura ( Project A-Ko , Steamboy , Tekkonkinkreet ) is the art director. Taisei Iwasaki ("Kyoshinhei Tokyo ni Arawaru" short, Kanojo wa Uso o Ai Shisugiteru live-action film) is composing the music.

Funimation streamed the anime with English subtitles as it aired in Japan. The company also streamed an English Broadcast Dub in starting in May.

Update: Toho posted a preview of the final episode:
