Mana Manipulation vs. Ki: The Beginning After the End Magic System Explained
If you’ve been following The Beginning After the End long enough—whether through the manhwa panels or the light novel—you’ve probably noticed something: Arthur Leywin doesn’t just feel stronger… he feels fundamentally different. And the reason isn’t just plot armor or reincarnation tropes. It’s the fascinating clash between Ki and Mana, two energy systems that operate on completely different rules.
As a long-time progression fantasy fan (and someone who’s fallen deep into the TBATE rabbit hole), I genuinely think this dual-system approach is what elevates the series above many others. It gives Arthur’s growth logic, depth, and a satisfying “earned” feeling. Let’s break it down in a way that feels less like a textbook and more like a fan discussion thread you’d stumble across at 2 AM.
Ki: The Forgotten Foundation of King Grey’s World
Before Arthur was Arthur, he was King Grey—raised in a world without traditional magic. Instead, fighters relied on Ki, a purely internal energy.

What makes Ki interesting is how limited yet precise it is. Unlike mana, it doesn’t exist in the environment. It’s cultivated entirely within the body.
- Ki enhances physical abilities — speed, durability, strength
- No elemental projection — no fireballs or lightning storms
- Heavily dependent on natural capacity — genetics mattered a lot
Grey’s biggest disadvantage was his small Ki pool, but instead of holding him back, it forced him to refine his technique to extreme levels. That precision later becomes the key to Arthur’s dominance.
Think of Ki as high-performance muscle control, while mana is more like reality-shaping energy.

Mana: The Core of Dicathen’s Power System
Once reincarnated, Arthur enters a world ruled by mana—an energy that exists everywhere. Unlike Ki, mana is both internal and external, giving mages a much broader toolkit.
Most people don’t awaken mana immediately. Their mana core forms during adolescence, and this core determines their strength. TBATE’s structured progression system makes power growth feel logical and earned.
| Stage | Sub-Stages | General Power Level |
|---|---|---|
| Black | None | Initial, impure core |
| Red | Dark / Solid / Light | Beginner mage |
| Orange | Dark / Solid / Light | Intermediate |
| Yellow | Dark / Solid / Light | Veteran level |
| Silver | Initial / Mid / High | Elite/Lance tier |
| White | Single stage | Peak human potential |
Each stage represents purification rather than simple accumulation, meaning control matters just as much as raw power.
Augmenters vs. Conjurers: Two Paths of Mana
Mana users in TBATE generally fall into two categories.
Augmenters channel mana through their bodies, enhancing physical combat abilities and excelling in close-range fights.
Conjurers project mana outward, shaping elemental spells and focusing on ranged combat and battlefield control.
Most mages are naturally inclined toward one path, but Arthur blends both seamlessly.
Why Arthur Leywin Breaks the System
Arthur didn’t just learn mana—he applied Ki principles to it. Because he already understood internal energy manipulation, he formed his mana core as an infant, mastered mana flow faster than prodigies, combined augmentation and conjuring, and achieved multi-elemental control early.
This isn’t just talent; it’s cross-system optimization.
The Game-Changer: Mana Rotation
One of Arthur’s most iconic techniques is mana rotation, keeping mana constantly circulating through his body.
- Faster recovery
- Core purification while moving
- Constant combat readiness
- Reduced downtime between battles
To other mages this seemed impossible, but for Arthur it was simply Ki training adapted to mana.

Elemental Versatility: Another Result of Hybrid Knowledge
Most mages are born with one or two elemental affinities, but Arthur eventually controls all four basic elements.
- Fire
- Water
- Earth
- Air
This versatility reflects his understanding of energy flow rather than genetic luck.
The Bigger Picture: Aether and the Evolution of Power
Later in the story, the concept of Aether is introduced. If mana is water, Aether is the container. Arthur’s ability to manipulate Aether makes sense because he mastered internal energy, external energy, and overall control.
Quick Comparison: Mana vs. Ki
| Aspect | Ki | Mana |
|---|---|---|
| Source | Internal only | Internal + External |
| Usage | Physical enhancement | Elemental spells + enhancement |
| Flexibility | Limited | Highly versatile |
| Growth | Mostly fixed | Cultivated and purified |
| Arthur’s Advantage | Prior mastery | Hybrid application |
Final Thoughts from a TBATE Fan
What makes the Mana vs. Ki dynamic so compelling isn’t just the mechanics—it’s how it shapes Arthur’s identity. He isn’t simply overpowered; he’s optimized.
He brings discipline from one world into another that never considered those techniques. Every breakthrough ties back to earlier foundations, making progression feel earned.
Arthur isn’t just strong. He’s the result of two worlds colliding—and that’s what makes every fight satisfying to watch.
