Soul Eater is weird. It’s got that specific late-2000s energy—gothic, moon-with-a-bleeding-face, Halloween vibes—that really shouldn’t work as well as it does. But if you peel back the layers of Atsushi Ohkubo’s masterpiece, you find something way more interesting than just cool scythe fights. Specifically, the relationship between Black Star and Soul.
It’s easy to focus on Maka and Soul. They’re the protagonists. They’re the ones on the volume covers. But the moments where Black Star and Soul Evans have to sync up? That’s where the series actually explores the messy, ego-driven reality of being a "Meister" and a "Weapon."
Most shonen anime treat power-ups like a level-up in a video game. You train, you get a new move, you win. Soul Eater doesn't do that. It focuses on Soul Resonance. To actually fight, two souls have to vibe. They have to match wavelengths. And honestly, Black Star is probably the hardest person in the entire DWMA (Death Weapon Mutation Academy) to vibe with.
Why Black Star and Soul Shouldn’t Work (But Do)
Think about Black Star for a second. He’s loud. He’s arrogant. He literally yells "I am the man who will surpass God" while trying to be an assassin. He’s the physical embodiment of "Look at me!" Now look at Soul. Soul is the definition of "cool." He’s detached, observant, and tries way too hard to play it off like he doesn't care.
On paper, they’re a disaster.
When they first try to team up because Maka and Tsubaki are sidelined, it’s a total train wreck. Black Star’s ego is a physical weight. Soul can’t find the rhythm. In the anime and manga, we see this play out during the fight against Sid Barrett. They can't even move properly. Why? Because Black Star wants to lead, and Soul isn't a passive tool. Soul is a partner.
This is the brilliance of their dynamic. It highlights the flaw in the Meister/Weapon system. If the Meister views the Weapon as just a sword, the resonance breaks. Black Star had to learn that he wasn't the only star in the room.
The Problem of Wavelengths
In the world of Soul Eater, your soul is a reflection of your personality. Black Star has a "Big Soul." It’s huge, aggressive, and overwhelming. Soul Evans, on the other hand, has a soul that is constantly fighting internal demons—literally, there's a little red demon in a tuxedo living in his head.
When they try to connect, it's like trying to plug a high-voltage industrial cable into a delicate home stereo system.
It blows the fuses.
They had to find a middle ground. It wasn't about one person changing for the other. It was about mutual respect. Soul had to acknowledge that Black Star’s raw power was a tool for the greater good, and Black Star had to realize that Soul’s "coolness" was actually a stabilizing force.
The Turning Point: The Fight Against the Kishin
There’s a specific nuance to how Black Star treats Soul compared to how he treats Tsubaki. With Tsubaki, he’s protective but also somewhat reliant on her kindness. With Soul, it’s a brotherhood of idiots. They’re competitive. They’re both trying to prove they’re the best.
When things get real—like during the Battle for Castle Baba Yaga or the final push against Asura—that competition turns into a terrifyingly effective synergy.
They don't just fight well; they improvise.
Black Star’s physical capabilities are off the charts. He’s one of the few humans who can hit you with his bare hands and transmit his soul wavelength directly into your internal organs. That’s horrifying. When you add Soul’s ability to amplify that wavelength, they become a wrecking ball.
It’s interesting to note how the manga handles this differently than the 2008 anime. If you’ve only seen the show, you’re missing out on the late-game Black Star developments where he starts to truly understand the "Path of the Warrior." He stops being just a loud kid and becomes something... well, scary. And Soul is right there with him, providing the edge.
Breaking Down the "Cool" Facade
Soul Evans spends 90% of the series pretending he’s too cool to care. But his partnership with Black Star exposes his vulnerability. You can’t resonate with someone if you’re wearing a mask.
To work with Black Star, Soul had to drop the act.
He had to be okay with being the support. In a world where Weapons often feel like the "junior" partner, Soul’s willingness to push Black Star to his limits shows a level of maturity that Maka often struggled to reach in the early chapters. It’s a different kind of trust. It’s the trust of two guys who are willing to break their own bones to win a fight.
Lessons from the Duo: Real-World Takeaways
We can actually learn a lot from these two fictional teenagers. Most of us work in teams. Whether it's a corporate job, a creative project, or just a friendship, the "Soul Resonance" metaphor is surprisingly accurate.
- Ego is a silencer. If you’re too busy shouting about your own greatness (the Black Star method), you won't hear what your partner is trying to tell you.
- Vulnerability is a prerequisite for success. You can’t collaborate effectively if you’re hiding your true thoughts or pretending to be "cool" (the Soul Evans method).
- Shared goals trump personality clashes. These two couldn't be more different, but they both wanted to protect the world and be the best. That shared vision allowed them to overlook the fact that they probably annoyed the hell out of each other.
Honestly, the "Black Star and Soul" pairing is the ultimate "Odd Couple" trope done right. It’s not just for laughs; it’s a deep dive into what it means to actually trust someone with your life.
How to Apply This to Your Life
If you’re struggling to work with someone whose personality clashes with yours, stop trying to change them. Instead, look for the "Resonance."
What is the one thing you both care about? Focus on that.
Let the personality quirks become background noise.

In Soul Eater, the characters who tried to force their will on others always lost. The ones who opened up, accepted their flaws, and matched their "wavelengths" were the ones who saved the world.
What to Watch or Read Next
If you’ve finished the anime and feel like something was missing, you need to read the manga from Chapter 32 onwards. That’s where the story diverges. The character development for Black Star in the manga is arguably the best in the entire series. He goes from being a comic relief character to a literal force of nature.
You should also check out Ohkubo’s other work, Fire Force. While it’s a different world, you can see the evolution of his ideas about "human connections" and "inner fire" that he started with Black Star and Soul.
The legacy of this duo lives on in modern shonen. You can see shades of their dynamic in Jujutsu Kaisen or My Hero Academia. But nobody quite matches the raw, chaotic energy of a blue-haired assassin and a demon scythe who just want to be "cool" while they beat up gods.
To dive deeper into the lore, start by re-analyzing the "Soul Eating" mechanics. It’s not just about the power—it’s about the burden the weapon carries for the meister. Once you see that, the Black Star and Soul fights look completely different.
Take a look at the "Enchanted Sword" arc again. Notice how Black Star’s shadow changes. That’s the moment his soul starts to grow, and it’s the moment he truly becomes worthy of a partner like Soul.
