With the killing, I changed.
To the extent that my name soared in prominence, the humans that came to challenge me grew in volume.
Man, Monster (魔, ma), and Hero (英雄, eiyuu) are as a cyclical order of superiorities (循環する勢力, junkan-suru seiryoku, "potency that cycles").
Humans are incapable of overcoming Monstrosities (魔, ma).
Even if it be that many thousands of troops are dispatched, so long as they are 『Humans』, contending on equal footing against 『Monsters』 (怪物, kaibutsu) is an impossibility.
In accordance with such a principle, I was further escalated in my aspect (属性, zokusei, "element / attribute / nature") as a Monstrosity (怪物, kaibutsu).
Such is the trilemma (三すくみ, sansukumi) of Man, Demon (悪魔, akuma), and Hero.
Man can obtain no victory against Monstrosities (魔, ma); Monstrosities fall before Heroes; and Heroes are subject to the regulation (粛正, shukusei, "correction / administration; enforcement of discipline"; alternatively, "purging of undesirable elements") of Man.
Per this principle, the Medusa that had become as a Monstrosity slaughtered the masses of Men, growing therefore; and cycling along the circuit, she became as a sacrifice to a single hero
