Chapter of Memories: No one is sure when Anti-Entropy was actually established, but it is estimated to be at least fifty years ago. The current leader of Anti-Entropy is Walt. The purpose of its existence is to reconstruct human bodies, so that they may survive close contacts with the Houkai and eventually defeat it. As the organization's ideals are highly in contrast with the Shicksal's, the two sides are frequently in dispute.
Chapter of Birth: After the second Houkai, Walt began to recruit talents to counter Shicksal and built up Anti-Entropy. Then for the whole plan of Walt, Anti-Entropy began to research Archeotech and built an ark fortress in space.

追溯篇：逆熵创立时间并不明确，推测至少在五十年前。现在首领是瓦尔特。逆熵的目的是利用崩坏能改造人类，使她们能够在崩坏中生存，并消灭崩坏。由于与天命的理念相对立，双方之间也频繁发生冲突。
新生篇：在二次崩坏后，瓦尔特为了对抗天命着手开始吸纳人才，组建起了逆熵。而后为了瓦尔特的计划，逆熵涉足远古科技，并在亚空间建立了方舟要塞。

設立時期は明らかではないが、少なくとも50年前と推測される。現在の首領は不明。ネゲントロピーの目的は崩壊エネルギーを利用して人類を改造し、崩壊中でも生き延びられるようにし、崩壊を滅ぼすこと。天命組織の理念とは対立するため、双方の間では頻繁に衝突が起きている。

설립 시기는 명확하지 않으나 최소 50년 전으로 추정된다. 현 수장은 불명. 네겐트로피의 목적은 붕괴 에너지를 이용해 인류를 개조하여 붕괴 속에서도 생존 가능하게 하고, 붕괴를 소멸시키는 것이다. 천명 조직의 이념과 대립하기 때문에 양측 사이에 빈번한 충돌이 발생한다.
