Battle Spirits [Re] Zekkai no Kū

During the Bakumatsu period, a new way of fighting was born: Battle Spirits, a card game that allowed samurai to fight without one of them having to die. But not everyone is on board with this new way of doing things, and it may be up to Ku, the son of a temple where a sacred Battle Spirits deck is enshrined, to figure out how to change the world.

Battle Spirits [Re] Zekkai no Kū is based on the Battle Spirits TCG. The anime series is streaming on Crunchyroll on Tuesdays.

I firmly believe anime based on games should be accessible and enjoyable even if you've never played the game. (And possibly even more enjoyable if you have.) Battle Spirits [Re] Zekkai no Kū doesn't quite pull that off, despite being a standalone series in a franchise with a ton of different iterations, both anime and manga. It does, however, manage to be unintentionally hilarious by setting its card-battler scenario in the Bakumatsu period. I'm not sure why seeing Edo-period kids whipping out English attack names and cartoony monsters was so funny to me, but I thoroughly enjoyed that part of the episode.

Basically, the idea here is to give a more-or-less origin point for Battle Spirits as a TCG. According to the show, it has become a way for opposing sides to fight without killing each other, which sounds admirable to us, but we're not 19th-century samurai. While children seem perfectly happy with this and keen to compete at Battle Spirits festivals, adults are less thrilled, as we see in the bookended narrative about two adults fighting and unwilling to settle for ignominious survival after defeat by card game. This setup definitely has some potential, and I'm curious as to how our trio of child protagonists Ku, Yui, and Ibuki is going to work to create actual change. Zetsu, one of the adults, has been watching them from the start, and he doesn't seem particularly impressed.

This episode falters by devoting most of its runtime to a battle between Ku and Ibuki. If you're not invested in the game and don't understand its rules, most of it drags. How do turns work? Why are the monster names in English at this point in history? Is playing a fire deck against a water one really a good plan? Without an investment in the game itself, watching plasticky CG monsters go after each other just isn't that interesting, even with enthusiastic narration from Ku's dad and Yui, the token girl. I appreciate that someone was trying – Ku's phoenix at the end of the fight is neat-looking – but whoever thought that putting life points as actual physical bumps on the boys' bodies was a good idea should perhaps be talked to. On Ibuki's arm, they look like pustules. On Ku's chest, they look like extra nipples. Not great.

I am curious how this will fare with Battle Spirits players and franchise fans. As a non-TCG person, it's very much not working for me. But if I get to watch the Shinsengumi play a card battle, I may change my mind.

Battle Spirits [Re] Zekkai no Kū is far from an amazing anime, but I think I played too many Yu-Gi-Oh! games as a kid not to have a soft spot for this one. A flagrant advertisement for Bandai and Sunrise's Battle Spirits card game, this anime seems like a retelling of Japan's tumultuous Bakumatsu period, but with card games settling disputes rather than political violence. While I'm not the biggest fan of this kind of historical reimagining, the premise is stupid enough to be endearing to me, and I hope the show finds its audience throughout the season.

While we get a general sense of the characters that will drive this story forward, like the spirited lead Ku, the tempered Ibuki, and Yui, who is a girl and also there, the main objective of this inherently promotional piece of media is to establish the Battle Spirits card game to new audiences. I'll admit, choosing to render these battles and the creatures within them in PlayStation 2-style graphics immediately piqued my interest, as that's what video game versions of card games look like in my mind as a nerd born in 1995. I also appreciate that this episode threw its audience into a few Battle Spirits games rather than providing a broad tutorial that would have killed the pacing. The team behind this anime made the bet that if they make this game look cool enough in the show, viewers will research the game and how to play after watching it, which is totally what I did once the end credits started to roll.

If I had one big critique of this first episode, it's that it seems like Ku only won his final match against Ibuki because he used a core gameplay mechanic he ignored throughout the episode. That's kind of a bummer, as the main takeaway from this episode is that you can win this game if you have a base-level understanding of the rules rather than a showcase of some of the unique mechanics or strategies within this gameplay system, though hopefully future episodes will get more into the minutiae of this game.

While the streets are clamoring for a remake of the original Yu-Gi-Oh! anime, I don't think Battle Spirits is going to satiate people's appetite for a dark fantasy card game series, but Battle Spirits [Re] Zekkai no Kū is a better anime of this type, and hopefully it inspires a love of card games in younger audiences like Yu-Gi-Oh! did for me back in the day.
