Warning: Rework in Progress
Merging different worlds and power systems into one fanfic is exhausting. Some people claim there's no "Mana" in Tensura, even though "Mana circuits" are frequently mentioned in the books. I even showed them a wiki page proving its existence.
By definition, Mana is a combination of material and spiritual power—the same definition you'd find for "Chakra" in the Naruto wiki. That's why I made them analogous, with both ultimately tied to stamina. The main difference is how they're used: Tensura characters channel them for skills, magic, and manipulating magicules, while Naruto characters shape them through hand seals to breathe fire or enhance their bodies. Even in Tensura, hand signs exist—like when the Elf Duke used them alongside chants, essentially wielding Chakra in a different way.
Then, I took another look at Magicules and Senjutsu in Naruto. Senjutsu is dangerous—if you can't handle it, you either turn to stone like a frog or mutate into something monstrous. That aligns with the nature of magicules, which radiate energy that can cause mutations. It made sense to me that Naruto characters rarely use magicule-based techniques. Normally, you can only acquire "nature energy" by signing a contract with a giant entity, which is why Senjutsu is so rare—unless, of course, you have Hashirama cells, but that's another story.
Some might argue that magicules are far denser than anything in Naruto, making them inherently stronger. But seriously? Denser = Stronger? If that's your logic, go ahead and write a thesis on it—but that just proves you haven't actually read their definitions:
- Magicules act like radiation, similar to gamma radiation (think Hulk). They are simply radioactive light particles. Which is my you can get radiation poisoning from it which they dubbed as Magicules poisoning, and a more prolonged exposure would just... well, it would just get you cancer.
- Chakra functions like boiling water—you need to circulate it to make it work.
- Mana also works like boiling water, since Mana circuits are frequently mentioned in the books. That's why Mana and Chakra are analogous.
-Spiritrons aren't even an energy source—they're just another subatomic particle, like protons and neutrons, commonly found in magicules. In simple terms, they're just the specialized building blocks of magicules. Or to dumb it down even more: magicules are made up of spiritrons.
- Haki and Aura are practically the same, but technically different, Haki is the skill, Aura is the energy. Aura isn't just Haki—it's a new kind of energy exuded when someone has a high concentration of magicules. However, it is NOT magicules. It also has anti-magic properties, meaning it can bypass magical defenses. This allows techniques like Battlewill, a composite combat style that lets warriors cut through magic. Rimuru demonstrated this during his B-Class Adventurer exam when his Aura Slash sliced through a demon's magicules. Later, these skills were refined into Hakurou's haze techniques, eventually forming what became known as Yojutsu (Mystic Arts). Personally, I prefer "Yokai Techniques" since the "Yo" clearly comes from "Yokai," but whatever translation makes people less confused, I guess.
So far, only turn null and stardust had insufficient definitions. One was only written as "A primordial energy that veldanava used to create the world", while the other was just "possessing destructive power beyond that of spiritrons." If you're going to make your own personal headcanon, at least open the Wiki.
The explanation of "Denser = Stronger" is not only superficial, it's also boring. Though I suppose some people would rather read fanfiction that focuses more on the character interactions without thinking all those complicated parts, even though they ultimately read some harem smut that beats all the interactions between characters as their original reason to read fanfictions.
Anyway—
The new version of this book will be a Naruto x JJK crossover, with two completely distinct power systems. Since Cursed Energy and Curses originate from negative emotions, they follow entirely different rules. To keep the lore consistent, both energy systems will be clearly defined and kept separate.
If you complain that I repeat it over and over, but then says superficial things like "Magicules are much denser" or "[Insert shonen energy here] is way stronger" in the next chapter right after you complained, that's on you.
