マイ・セイレイドウメイ Power System

Human Spirit Hybrid
The power system used in My Spiritual Alliance has two modules which include a system for Humans and a branching system for Spirits. These are represented by P ratings (for humans and spirits) and CE values (Spirit only).

Power is the standardized measurement of influence on reality from a being. Unlike simplistic strength metrics, Power is not measured by raw power alone. and is instead calculated with 3 measures:

Longevity: How long an ability can be sustained
Range: How far an attack extends
Force: How much direct impact it exerts (including collateral damage)

This tri-metric model was adopted because of it's unmatched ability to reflect a power's realistic damage potential and level of control rather than bursts of brute force.

Both Humans and Spirits possess a Power rating though the source differs:

Humans: Power manifester though external sources (Power Rings) and stabilise depending on will, discipline or neural regulation.
Spirits: Possess power through the nature of their being and the purpose they define by their death.

For Spirits, power does not increase through raw energy and instead gets amplified by their Cursed Energy rating using this formula: T= P*(CE/100)*E(CE efficiency))

A phase is the umbrella term for what the ability is able to do. Powers are usually a single-phase ability, which allows the user to essentially do one thing with their powers (e.g. Chronostasis can only disrupt time during movement of the opponent). However, they are known to be able to transcend to multi-phase abilities through training and meditation; very few powers naturally begin on multiphase operation.

Powers with natural multi-phase operation are far rarer than single phase powers with only less than 1% of the global population having one. These abilities are researched to have up to 4 phases. The origins of these powers are yet to be discovered however it is speculated that they appeared before the concept of time itself, this has lead to conspiracy theories broadening on DSTRT (the Twitter of MSA) with many speculating the "mess of a pre-defined universe" being the core reason why these powers exist. Additionally they are also found to have far higher power ceilings than single phase powers however this depends ont eh architecture and stabuility of the power as they are also known to be very jittery and unreliable, the oldest of multi-phase powers is Elimination which at it's lowest form is a dual phase ability operated currently by Eizo Kisaragi at P89.

Cursed Energy is a dense metaphysical substance formed when souls fracture under extreme emotional strain at the moment of death. Common examples of such situations include; Violent/ unnatural deaths, strong unresolved emotions, a soul fails to release it's final emotional state. This unresolved emotional mass condenses into Cursed Energy which becomes the fundamental existence of a spirit. Cursed Energy us not inherently bad, it's simply an expression of the density and pressure of emotional residue.

Japanese (post-SMC):

Cursed Energy: 怨力 (Onryoku)
SoulMist: 霊霧 (Reimu)

Korean (Pre-SMC):

Cursed Energy: 한기 (Hangi)
SoulMist: 혼무 (Honmu)

Before the rise of the Spirit Marriage Corporation (SMC) and modern spirit engineering, Cursed Energy had already existed for over thousands of years in it's original, unregulated form. Early CE possessed traits such as:

Extremely high volatility
Minimal internal regulation
High power capacity even for low-tier spirits

Due to spirits having lacked knowledge or structure to process this energy it often gave symptoms such as:
Overwhelming newly formed spirits
Internal erosion or madness
Spontaneous instability or dissolution

Currently, this version of Cursed Energy is only found in Akari Nakamura and within Elimination (Eizo Kisaragi).

Alliances between humans and spirits have always been intended to bring balance and stability to the world as humans provide the necessary emotional grounding and intent while spirits provide energy density and longevity which results in a system that self-sustains however when misaligned it collapses.

SMC uses alliances to regulate spirits and humans by allowing them to be the 3rd man in the relationship using specialised infrastructure that is embedded within every means of modern life.
