A new Battle Spirits series starts streaming
Crunchyroll confirmed on Tuesday that it is streaming Battle Spirits [Re] Zekkai no Kū, the newest television series in Bandai's long-running Battle Spirits franchise. The show premiered the same day at 11:00 p.m. JST on Tokyo MX and other Japanese channels, so the simulcast is landing alongside the domestic broadcast.
Who is behind it
Masashi Kudo, whose credits include Terminator Zero, Sanrio Boys and Hayate the Combat Butler! Cuties, directs the series at Bandai Namco Pictures and is also credited with the original character designs. Toshizo Nemoto, who worked on Log Horizon and Metallic Rouge, is handling series scripts, and Bandai Namco Pictures is credited with planning the production. JAM Project perform the opening theme, Here we are!, with Himegoto on the ending theme, Pulse.
The cast
Taichi Kusano leads as Kū Bashin, a cheerful Battle Spirits fan who wants to get stronger, opposite Daiki Hamano as Zetsu Ajara, a feared Eternal Battler assassin. Hiro Shimono, Mariya Ise, Nana Mizuki, Megu Umezawa, Akira Ishida, Daisuke Ono, Jun Fukuyama and Shizuka Miyano round out the main roster, with Junichi Suwabe narrating.
A card game that keeps coming back to television
Bandai launched the original Battle Spirits trading card game in 2008 and brought it to the United States in 2009; the cards represent dragons, demons and other spirits that players command in battle. The franchise's most recent video game, Battle Spirits: Connected Battlers, released on PlayStation 4 and Switch, and the anime has been revived repeatedly rather than retired.
Our opinion
Battle Spirits is one of the quiet survivors of the card-game anime boom, and the reason is structural rather than sentimental: Bandai owns the game, the cards and the animation studio, so a new series can be commissioned to refresh the card pool without negotiating with anyone. That is why a franchise that never had a global breakout hit is still producing television in 2026 while louder contemporaries have stopped. The risk is the same ownership advantage inverted. When the show exists to sell packs, the storytelling can coast on new cards rather than new ideas, and simulcast audiences are quick to notice.
