Power System Braining.

First of all lets analyze deeply each popular anime's power system. Ground up

* Naruto
* One Piece
* Demon Slayer
* Chainsaw Man
* Magic Games

## Naruto

In Naruto we have Chakra. Chakra is universal, meaning everyone has it. But everyone doesn't have the same potential. So that means Chakra is genetic or randomized to a point. Kekkei Genkai are definitely genetic, and Elemental Affinities are universal.

So what we take away from this is:

* Elemental power system (Five Affinities)
* Genetic power system (Kekkei Genkai)
* Clan system (Bloodlines)
* Somewhat randomized potential (Talent)
* Ki Type Energy (Chakra)
* Universal Energy Force (Chakra)
* Train to improve strength and affinity.

## One Piece

In One piece, we have Devil Fruits, Haki, Fighting Styles, and Swords, also Technology. Devil Fruits are NOT universal. They are something rare and considered mythical in the world. However there is a BIG tradeoff for eating them. Haki is something you develop. It is mixed universal and talent oriented. Everyone can train it but some people are more proficient at it. Swords, and Fighting Styles are something that people train by themselves. Swords mainly are a type of legendary artifacts.

So what we take away from this is:

* No universal life force Energy
* Physical way to obtain abilities (Gain power but with tradeoff! Similar to curse)
* Latent potential in all humans, but affected by talent (Haki)
* No restrictions towards physical abilities. (Fighting Styles)
* Artifacts (Swords)
* Incremental Strength Gain (Train to improve)

## Demon Slayer

In Demon Slayer, we have Breathing Styles, and Demon Arts. Demon Arts are a Genetic or random thing, since it messes with the DNA of the transformed Demon. However, Breathing Styles are something passed down generation by generation to fight off Demons. They are something that is tied to physical strength and endurance, and MASSIVE, massive training. We also have slayer marks which are basically curses.

So what we take away from this is:

* No universal life force (No ki!)
* Breathing is something you train over time, specialty (Like a Martial Art!)
* Breating Styles are taught by trainers, and strength is determined by training and potential! (Potential coming into play again lol)
* Demon Arts are genetic and powered up by MURDER! (Basically training)
* Curse type with Slayer Marks

## Chainsaw Man

In Chainsaw Man we have raw strength, and then Devils, Hybrids, and Devil Contracts. Devil contracts are kind of random, but also cursed. Devils may take nothing away from you, but they may also take everything away from you. Depends if they like you or not. Hybrids are Devils who fused with a Human, basically some form of advanced contract. Devils are powered by fear on them, basically Negative Emotions.

So what we take away from this is:

* Mythical creature based (Devils)
* Powered by Human Negative Emotions
* Mixes with Humans
* Basically Curses
* Can somewhat be trained. But depends more on the devil's power. (Not so Shonen!)
* Very random somehow

## Any RPG

There is usually MAGIC included in any form of rpg. They follow a BAR, and this BAR is limited, its like a form of energy. MAGIC is really wide and can be interpreted in many ways. (Elemental, Technological, Prehistoric)

Main Points:

* ENERGY SYSTEM
* Wide in terms of potential and diversity
* Usually Elemental
* Incremental by training, sometimes fixed.
* More powerful MAGIC requires more ENERGY!
