Gundam GQuuuuuuX x Yonezu Kenshi: Plazma Deep-Dive

Okay, so if you care about anime music, mecha history, or both, this one has real nerd gravity. The song is called Plazma, the series is 機動 (kidou, mobile) 戦士 (senshi, warrior) Gundam GQuuuuuuX, and the whole package is basically Sunrise saying, loudly, that the opening song still matters. Good, because it does.

Gundam GQuuuuuuX brings Kenshi Yonezu into the cockpit

No joke: the official video for Plazma confirms what a lot of fans were hoping for: Kenshi Yonezu is performing the opening theme for Kidou Senshi Gundam GQuuuuuuX. The series itself is a big deal already, because it arrives as part of Gundam's 45th anniversary era, which means the music had to carry franchise weight, not just sound catchy over a title card.

And here’s the thing: Yonezu isn’t some disposable pop name slapped on for marketing fluff. He’s one of those artists who can make an anime opening feel like part of the world, not just a promo reel. That matters with Gundam, because this franchise has always loved the tension between spectacle and mood, the machines, the war, the loneliness, the whole thing. Plazma has to do more than slap. It has to carry.

For Japanese learners, this is also a neat little vocab moment. Gundam titles often use kidou for mobile, senshi for warrior, and in everyday anime talk you’ll hear words like 主題歌 (shudaika, opening theme song) for opening theme and エンディング (edingu, ending theme song) for ending theme. Not fancy, not hard, but useful. And if you’re the kind of person who pays attention to credit rolls, this is exactly the kind of context that makes all those words stick. Sounds good, right?

Why Plazma fits Gundam better than a random pop-opener

Did you know that...? Gundam openings work best when they feel slightly larger than the show itself, and I mean that in the least corporate way possible. The best ones don’t just say, “here is the show”, they say, “here is the emotional weather report for the show.” That’s why tracks like this can become part of franchise memory, even when you’re years past the actual broadcast.

Yonezu's music usually has that push-pull thing going on, polished but restless, melodic but a little bruised, and that’s exactly the sort of energy Gundam tends to eat up. If GQuuuuuuX is aiming for that sweet spot between legacy and reinvention, Plazma is doing a lot of the heavy lifting before a single mobile suit even moves. It sets tone, pace, and expectation, which is half the battle with a franchise this old. The other half is making the mecha choreography land. Classic Japan, isn’t it?

What many overlook: an opening theme can shape how a show is remembered in Japan far beyond the episodes themselves. People hum these things, clip them, meme them, argue about them, and then, years later, one opening becomes the shorthand for an entire season. Gundam has been doing this for decades, and when a major artist like Yonezu steps in, the song becomes part of the franchise's public face, not just background music. That’s not nothing.

Suisei's ending theme gives the project a second pulse

To be fair, the ending theme is just as interesting here, because Hoshimachi Suisei performs Moudou Natte mo Ii ya, and that gives GQuuuuuuX a very 2020s kind of one-two punch. You get Yonezu on the opening, Suisei on the ending, and suddenly the series is speaking fluently to both mainstream music fans and anime-native listeners. That is smart. Annoyingly smart.

And here’s where the collaboration stops being just a music-news bullet and starts feeling like a franchise statement. Gundam is 45 years deep, but it isn’t behaving like a museum exhibit. Bringing in Suisei, who already has serious credibility among anime and VTuber audiences, says the production wants current energy, current fandom behaviour, current attention spans. That doesn’t guarantee the show will be good, obviously, because studios can still fumble the actual story. But as a cultural move, it makes sense.

Pro tip: if you’re learning Japanese through anime music, ending themes are underrated. They’re often slower, easier to catch by ear, and packed with everyday phrasing that sticks better than the more dramatic bits in dialogue. So even if you come for Plazma, don’t sleep on the ending. It might be the one that settles in your head at 1 a.m. when you’re trying to go to bed and absolutely failing. Wait, there’s more.

Why this collab has such high search value and nerd factor

Look, this is basically a perfect search-term cocktail, and I mean that in the least soulless way possible. You have Gundam GQuuuuuuX, Yonezu Kenshi, Plazma, Gundam 45 years, and Suisei all sitting in one news cluster, which is exactly the sort of thing fans will look up separately and then end up stitching together anyway. The nerd factor is high because each name pulls in a different fandom lane, and the overlap is where the fun starts.

My tip: if you’re writing or studying about anime music in Japanese, pay attention to how these collaborations are framed. The naming itself matters. A title like Plazma feels sci-fi without being clunky, and that suits Gundam's long habit of mixing real military texture with near-mythic scale. Then the franchise anniversary gives it historical weight, and Suisei on the ending keeps the project from feeling like it is only looking backwards. It is a clean little balancing act. Not bad, right?

At the end of the day, this is the kind of anime-music collaboration I’ll always take seriously, because it understands something simple: opening songs aren’t decoration. They’re memory hooks, identity markers, and sometimes the reason a show lives longer in the culture than it has any right to. I think I speak for a lot of fans when I say: if Gundam wants to go big, give it a song with actual ambition.
