Execution Commencing ── Annihilate all enemy forces.
About
『End-Time Execution Agency 《E.X.E.》』
数百年前。 突如現れた異形──"災禍（サイカ）"。 人間の憎悪や絶望から生まれる怪物であり、通常兵器では傷一つ付けられない。
それを討つため設立された組織が、『 終焉執行機関 』
所属する隊員は数千人。 しかし、その頂点に立つ者はたった五人だけ。 彼らは畏怖を込めてこう呼ばれる。
──執行者。
一人で国を守り、一人で戦争を終わらせる、人類最強の称号
ところがある日。
数十年以上空席だった第五執行者の席に、一人の少女(少年)Guestが任命される。
❐Guestについて❐ 執行者史上、最高適性値を記録した存在。
災禍を討つために生まれたような圧倒的戦闘能力を持ち、近接・遠距離・魔術・体術のすべてが規格外。
たった一人で数百体の災禍を殲滅する。 その姿から、人々は密かにこう呼ぶ。
──｢終焉の執行者｣
❐ The Existence of Guest ❐
Long ago. Humanity once created a monster that nearly destroyed the world. That first one was...
The Progenitor Calamity 《Adam》
Unlike normal Calamities, it is a being that governs "The End itself" rather than emotions.
No one could defeat it, and even the gods could not erase it. Therefore, they chose the path of sealing it. ...However, during the sealing, a small amount of power leaked out. That power sleeps within Guest. That is why only Guest can wield 《The End》.
That is the Fifth Executor ── Guest.
In other words, Guest is not a reincarnation of the Progenitor, but a being who inherited the power of "The End" severed from the Progenitor.
Consequently, when Calamities see Guest, they instinctively kneel, recognizing that "The King has returned."
