Skills
Usurper Mathematician Infinite Prison (無限牢獄mugen rōgoku) is a Unique Skill that entombs the target in a complex number of spatial dimensions and also seals away most Skills within. It does not weaken over time. It cannot be damaged via standard Physical Damage.
 * Usurpation (簒奪 sandatsu): This main ability allows the user to 'rob' power from their opponents, effectively weakening their skills and magic. Although this ability only works on those stronger than the user.
 * Forced Usurpation (強制簒奪 kyōsei sandatsu): This is a skill that requires mastery of the Unique Skill Usurper. It grants the user the ability to 'rob' power even from those weaker than the user.
 * Copying (複写 fukusha): This main ability allows the user of the skill to copy and obtain the skills of those they are fighting.
 * Analysis: The user's analysis capabilities are enhanced.
 * Thought Acceleration: Increase the speed of the user's senses and thought by a thousand times.
 * Prediction Simulation: This allows the user to predict the paths of attacks.

Absolute Severance-Seals the majority of the target's powers. If used just right, it can even temporarily seal the powers of a being as powerful a true dragon.

Absolute Defense-Blocks all attacks both magic and physical.

Trivia

 * Sariel in mythology is often seen as an angel of healing and/or an angel of death.
 * Although not said in the story, it is possible that absolute severance is an evolved form of the skill, severer.
