Who is the Strongest Teacher at Babyls? Every Staff Member Ranked
If you’re a true Welcome to Demon School! Iruma-kun fan, you know that Babyls isn’t your ordinary school. Here, strength, strategy, and bloodline magic dictate respect, and the teachers are just as dangerous—if not more—than the monsters roaming the Netherworld. While the anime teases their abilities, the manga reveals their full might, and trust me, some of these teachers could give even the bravest demons a run for their mana.
So, who truly rules Babyls when it comes to raw power and combat prowess? Let’s break it down, fan-style.
Understanding the Demon Ranking System
Before diving into the rankings, it’s crucial to understand how demon strength is measured in this universe:
| Rank | Description | Who Usually Holds It |
|---|---|---|
| Yodh (10) | Top-tier, basically untouchable | Demon King, Three Greats |
| Khet (8) | Elite combatants; teachers like Kalego | Top-tier faculty |
| Zayin (7) | High-level fighters, capable of taking down dangerous demons | Most standard teachers |
| Aleph (1-6) | Ranging from weak to moderately skilled | Lower-ranked demons & students |
Basically, a teacher’s rank is not just a number, it’s proof of their ability to protect students—and crush any threat daring enough to step onto campus.
Tier 1: The Apex Predators
1. Naberius Kalego (Rank 8 – Khet)
If there’s one teacher that makes fans quake in their boots, it’s Kalego-sensei. A member of the fearsome Naberius clan, he isn’t just a teacher; he’s a walking arsenal.
- Strengths: Unmatched discipline, deep magical knowledge, and his terrifying familiar, Cerberion.
- Role: Lord Sullivan’s trusted substitute and head of security. He isn’t just teaching students; he’s safeguarding the entire school.
Kalego is the kind of teacher who could turn a misfit class into a battle-hardened squad without breaking a sweat.
2. Balam Shichiro (Rank 8 – Khet)
Balam, the “Phantom of Babyls,” balances gentleness with sheer destructive power. While he may seem calm, crossing him in combat is a mistake you only make once.
- Bloodline Magic: Buzzer (Chimes of Deception)—detects lies instantly.
- Combat Style: Mix of overwhelming physical force and clever plant-based magic.
Between Kalego’s tactical genius and Balam’s brute strength, these two are the undisputed kings of the faculty.
Tier 2: The Elite Guardians
3. Opera (Rank Est. 8-9)
Officially Lord Sullivan’s assistant, Opera’s combat experience might overshadow even Kalego and Balam. While technically a “temporary teacher,” many fans speculate that Opera is secretly one of the strongest beings in the Netherworld, capable of taking on multiple top-rank demons simultaneously.
4. Barbatos Bachiko (Rank 8 – Khet / Special Tutor)
Bachiko isn’t just a tutor; she’s a long-range nightmare. Her archery is precise enough to turn a battlefield into a trap for any foolish enough to approach.
- Special Skill: 100% accuracy with massive mana expenditure—few dare to test her aim.
5. Dali (Rank 7 – Zayin / Teacher Supervisor)
Dali is the quiet powerhouse of the school. As the supervisor, even Kalego shows respect. Reddit and fan forums often speculate that Dali is hiding a Rank 8 or 9 status, preferring subtlety over flashiness to maintain order at Babyls.
Tier 3: The Specialized Experts
6. Morax Momonoki (Rank 7 – Zayin)
Morax is the embodiment of teaching with skill. Specializing in foundational magic, she is a steady force in the school, capable of defending against serious threats while nurturing student growth.
7. Bars Robin (Rank Est. 5-7)
Often underestimated due to his goofy demeanor, Robin has hidden potential that rivals even Bachiko’s archery technique. It’s the classic don’t judge a demon by their smile scenario.
Why Babyls Teachers Outclass Other Shonen Schools
Let’s be honest: Babyls isn’t just a school—it’s a survival zone. Unlike in other anime like My Hero Academia, every teacher is combat-ready, ensuring that even the weakest students have some protection. The “Wicked Phase” powers that are hinted at but not fully revealed only reinforce the idea that Babyls staff are elite predators, not just educators.
Final Thoughts
While Kalego and Balam clearly dominate the official rankings, the fan debates around Opera and Dali keep the discussion alive. With Season 4 approaching in April 2026, I’m personally excited to see how the power gap between students and teachers will shift. For now, though, the staff of Babyls remains the ultimate wall of defense, and anyone underestimating them is in for a rude awakening.
