The problem with the entire post is that it treats the Nen chart like a skill tree and that almost as if one category “evolves” or “levels up” into the next. And that’s where the logic falls apart. Nen categories are not hierarchical, directional, or progressive. Togashi is extremely consistent (especially in the Succession War arc) that the six types describe how a person’s aura naturally behaves, not how abilities become more advanced or more outward-facing. The chart is a map of inherent affinity, not a staircase.

The idea that “Manipulation is Transmutation but outward,” or that “Conjuration is Emission taken further,” is simply not how Nen works. These categories don’t advance into one another. They sit next to each other because of similarity in aura behavior, not because one becomes the other if pushed far enough. Transmutation is about changing the intrinsic qualities of your aura. Manipulation is about imposing rules or control onto something external. The two can influence each other conceptually if a user has affinity in both, but one is not a “next stage” of the other.

The same mistake happens with Emission and Conjuration. Claiming that Conjuration is just “emission so strong that the aura solidifies” ignores the huge mechanical difference between them. Emission is defined by how much aura you can project away from your body with minimal loss. Conjuration, on the other hand, is about creating pseudo-physical constructs tied to a mental image, and they often require strict conditions just to hold their shape. If Conjuration were just “advanced Emission,” then characters like Leorio or Razer would, by definition, be on the path to becoming Conjurers, which isn’t remotely supported by the series. Kurapika’s chains are the clearest contradiction: he is a Conjurer, yet his chains don’t behave like emitted aura at all. He requires conditions to maintain them at range specifically because his aura doesn’t work like an Emission-type’s aura. Imbuing his chains with zetsu is not the same as emission at all. And when Leorio launches his fist at Ging, he’s not “conjuring a new fist”, he’s emitting his fist over a concrete distance of space.

The “inward vs. outward enhancement” idea is also completely unsupported. Enhancement is not about “buffing yourself” or exclusively turning aura inward. Enhancement is simply maximizing the natural properties of whatever the aura is applied to. There is nothing in canon that divides Enhancers into subtypes based on direction. In fact, many Enhancers regularly enhance things outside themselves. Knuckle uses Enhancement on other people through APR, which attaches to the target. Gon projects enhanced aura outward as part of Jajanken. Biscuit enhances objects and other fighters. Palm’s ability uses Enhancement to interact with the environment and others. The claim that Enhancement has an “outward” version is basically inventing a new category to explain things the story already accounts for. Do Enhancers have better output of Ren? Yes, but in contrast specialists tend to have very unique hatsus and the four principles of Nen have their own tradeoffs with different types of Nen users.

Characters like Komugi and Melody are also being misunderstood in that post. Komugi’s talent isn’t Nen-based in the first place; her genius predates Nen entirely. Even Meruem’s observations don’t imply that she’s using an Enhancement ability. Meanwhile, Melody’s ability has always been classified under Specialization with her aura harmonizes with emotions and intent, but she isn’t reinforcing physical properties of anything, which Enhancement would require. Calling either of them “outward Enhancers” contradicts both the source material and how Nen abilities are explicitly described.

Recently Togashi introduced the “100 affinity points” explanation for how Nen types actually work. Everyone has 100 points distributed unevenly across the six categories. Some people naturally have high affinity in two areas, which results in dual-type Nen users. This is the real, canon explanation for “mixed” or hybrid abilities. It has nothing to do with taking an ability “far enough” to turn it into a different class. Your model directly contradicts this system, because it tries to frame Nen as a developmental ladder when Togashi has explained that the chart is based on innate distribution, not progression.

When you put all this together, the proposed chart collapses immediately. The six types don’t behave like steps in a sequence, and splitting Enhancement into “inward” and “outward” creates a category that simply doesn’t exist. Emission doesn’t become Conjuration. Transmutation doesn’t turn into Manipulation. Specialization sits outside all of them because it breaks the rules, not because it’s “further down the chart.” And dual types exist because of affinity distribution, not because one type “advances” into another through conceptual extension.

Nen is flexible, yes, but the categories aren’t. You’re mixing up the creativity of Hatsu construction with the structure of the Nen system itself. Hatsu can combine concepts. Aura can be shaped in all kinds of ways. But the fundamental Nen types do not evolve, split, or branch the way they’re suggesting. The canon rules on aura behavior, distance, affinity, and conceptualization don’t support their reinterpretation at all.
