If you’ve only watched the Uma Musume anime, you probably think Team Spica is the center of the universe. You’ve got Special Week, Silence Suzuka, and Gold Ship doing their thing. But if you actually boot up the mobile game and dive into the Main Story, things change. You’re not in Spica. You’re leading Team Sirius.
Honestly, it’s a bit weird at first. You expect the same vibe, but Team Sirius is a whole different beast. It’s a legacy team. It’s a group that feels like it has real weight because of who came before you.
What’s the Deal with Team Sirius anyway?
Basically, Team Sirius is the primary focus of the game’s Part 1 Main Story. Unlike the anime teams, this one is "yours." You play as a protégé, an assistant trainer who takes over after the original head trainer—the guy who coached the legendary Oguri Cap—decides it’s time to step back.
That’s a lot of pressure. Imagine walking into a locker room where the ghost of a Hall of Famer is still basically haunting the place. Oguri Cap is the "Ace" who built the team’s reputation, and after she retires, the team hits a bit of a slump. That’s where you come in. You’re trying to restore that "Sirius" glow.
The roster is stacked. We’re talking:
- Mejiro McQueen (The new pillar of the team)
- Rice Shower (The "Hero of the Heavens" and literal sweetheart)
- Winning Ticket (The ball of pure energy)
- Narita Brian (The powerhouse shadow)
- Silence Suzuka & Special Week (Yeah, they’re here too)
- Gold Ship (Because she goes wherever she wants)
It’s a mix of different eras. In real-life horse racing history, these horses didn't all run together. But in the Team Sirius narrative, they form this tight-knit, multi-generational family.
Why the Members Matter
One of the coolest things about the way the story is written is how it handles the "McQueen as a mentor" dynamic. You’ve probably seen the meme that Mejiro McQueen is the "youngest" member IRL because of when she was born compared to others, but in the game’s story, she’s the veteran. She’s the one who has to carry the torch after Oguri.
She takes Rice Shower under her wing. It’s actually pretty moving. Rice Shower is known for having a lot of self-doubt—people called her the "Heel" or the "Black Assassin" because she kept beating fan favorites. In Team Sirius, she finds a place where she isn't the villain.
Then you have Narita Brian. She’s terrifyingly strong. If Team Spica is about "fun and friendship," Team Sirius often feels like it's about "strength and legacy." Brian represents that raw, Triple Crown-winning power that makes the team feel like a serious contender on the world stage.

The Team Sirius Support Card: Is it actually good?
Okay, let’s talk mechanics. You get a specific group support card for Team Sirius. If you’re a Free-to-Play (F2P) player, this card is kind of a godsend, but it’s also a bit of a trap if you don't know how to use it.
It’s a "Group" type card. This means instead of just one girl, the art features the whole squad.
The Good Stuff:
- You can go on "dates" with the team to recover energy and boost stats.
- It gives you the gold skill 日本一のウマ娘 (Japan's #1 Uma Musume).
- It’s "free" in the sense that you earn copies by playing through the Main Story chapters.
The Not-So-Good Stuff:
In 2026, the meta has moved on a bit. While the Team Sirius card was top-tier for a while, newer scenarios like Project L'Arc or the more recent training modes often favor specific individual SSRs. However, for a new player, maxing out this card is basically a rite of passage. It gives you a solid foundation when you don't have a deck full of 4-star gacha cards.
The "Secret" Unlock
Here’s something most people miss. There is a "hidden" chapter in the Main Story.
If you’re playing through the later stages (around Chapter 5 or the Final Chapter of Part 1), you’ll hit a race where you have to select a "parent" or mentor for Special Week. If you’ve been using the Team Sirius support card and you’ve learned that "Japan's #1" skill, you can unlock an alternate path.
Winning that specific race with the right setup gifts you a 3-star Alt version of Special Week. It’s basically a free high-rarity character just for paying attention to the team's story. That alone makes the Team Sirius grind worth it.
Spica vs. Sirius: Which is better?
Fans love to argue about this. It’s like asking if you prefer the original Star Wars trilogy or the sequels.
Team Spica has the better "friendship" vibe. They feel like a group of dorks who happened to be fast. Team Sirius feels like an elite academy project.
If you look at the JRA (Japan Racing Association) stats of the real-life horses, Team Sirius is arguably more "prestigious." You have Narita Brian and Oguri Cap. These are horses that didn't just win; they changed the culture of racing in Japan. Oguri Cap caused a literal "cinder-gray" boom where people who didn't even care about racing were buying plushies of her.
In the game, this translates to a story that's a bit more dramatic. It’s about the burden of being the best.
Actionable Steps for Your Training
If you want to make the most of Team Sirius in your game, here is what you need to do right now:
- Clear the Main Story: Don't just skip the dialogue. The rewards (gems and support card copies) are tied to finishing these chapters.
- Max the Support Card: Go to the Circle Point Shop. You can buy extra copies of the Team Sirius SSR there. Do not leave it at Level 30. It needs the limit breaks to be viable in modern training.
- Use it for Stamina/Power builds: The card is great for mid-to-long distance runners because of the "dates" that help manage energy during those grueling 10-15 turn stretches where you can't afford to rest.
- Target the "Japan's #1" Skill: If you are building a Special Week or a McQueen for PVP (Room Matches), that gold skill is a massive buff for the final straight.
Team Sirius isn't just a backup for the anime characters. It's the heart of the Uma Musume game experience. It bridges the gap between the old legends and the new generation. Plus, seeing Gold Ship try to behave in a "serious" team is worth the price of admission alone.
Make sure you grab those card copies from the shop before you dump your points into anything else. Your stable will thank you.
