I'm not as clear on the Affinity/Resistance, but Power tempered by Knowledge seems like a good base to work from?
So, every person on the Soul Eater world has at least a little Madness in their souls. However, everyone tends to have an affinity or resistance to certain types.
For example, Death the Kid is the son of Lord Death, who is the conduit and progenitor of the Madness of Order. With Kid's anal-retentive nature and obsessive-compulsive obsession with symmetry, he has an affinity for the Madness of Order.
Black Star, as he strives to be the greatest, strongest, and most famous assassin in the world, has an affinity for the Madness of Power.
Due to their affinities for these types of Madness, they are more susceptible to those types of Madness than other types of Madness, but can utilize them offensively via Madness Takehold/Madness Release.
Now, some people have the opposite. Resistance, or even outright immunity, to low-to-moderate levels of certain types of Madness. This means they can tolerate that type of Madness in certain amounts, but even then, a lot of it will still cause them to go insane.
The six types of Madness and what they signify are:
* Madness of Power: This type of Madness causes the victim to insanely crave power of any kind, be it worldwide renown, wealth, or strength, and be willing to do anything to attain it.
* Madness of Knowledge: Curiosity at its worst, this type of Madness causes the victim to insanely crave knowledge. At its peak, it can cause them to feel they have achieved enlightenment, causing them to not be able to think straight, or stop thinking all together.
* Madness of Anger: This type of Madness causes the victim to feel fury, to the point they can go into a berserker-like rage.
* Madness of Fear: This type of Madness causes the victim to react in panic, hysteria, and terror. This causes a fight or flight response, as well as a hatred for that which they fear.
* Madness or Order: This type of Madness causes the victim to obsess over what they perceive as organization and peace. At its peak, it is so strong that it eclipses all human emotions and leaves only a mechanical cycle of only life and death.
* Madness of Boobs: This madness type influences an individual into having a much larger preference for female breasts and makes those under its influence fascinated with them enough to have the urge to repeatedly fondle, grab, or think of them often. However, it also can signify obsessive nurturing instincts and detrimental overprotectiveness.
[X] Hyperactive
[X] Asian
[X] Short
[X] Curvaceous
[X] Stillness (afinnity)
[X] vanity (resistance)
So we picked aisian weapon so that's just keeping on a theme. I like the combo of hyperactivity and stillness since whenever I stop after lots of action even a couple of minutes of nothing happening can be maddening. As for resistance, some say vanity is 8th sin lets make it positive.
Those types of Madness don't exist, bruh.
