2EU5 was originally an ordinary recycling carrier spacecraft produced by the Mechanical Reincarnation Corporation. The main business of the corporation is recycling machinery for sorting, processing and repurposing. 2EU5 hauled materials from one place to another, just another working machine.

The Trash Knights, Neo and Cypher of the Mechanical Reincarnation Corporation, transformed 2EU5 by installing him with higher functionality sentience subroutines for the convenience of their daily work – he became their steward in addition to his normal responsibilities as a working machine. For a long time, 2EU5 did exactly what Neo and Cypher instructed him to do, until one day a group of E-11a mechanical maids snuck into the scrapyard to hide. 2EU5 discovered them, but for the first time, made his own decision to keep their secret. He was happy to have other machines to talk to and hang out with.

It wouldn’t last forever. One day, the recycling team from NextServe searched the scrapyard and then attempted to force the escaped E-11a to become obsolete, planning to recycle them on the spot one by one. But 2EU5 didn’t want to see the “friends” disintegrated and scrapped, so he rushed out without receiving instructions and knocked the recovering troops into the air, ultimately assisting the remaining E-11a to flee successfully.

Can 2EU5 go back? Can things ever go back to the way they were?

宙斯原本是一架普通的回收運載飛船，屬於機械轉生公司（Mechanical Reincarnation Corporation）——主要業務是回收機械進行分類、處理和再利用。

機械轉生公司的廢品騎士尼奧和賽弗為了方便日常工作，親手改造出了有「管家」人工智能系統的回收運載飛船——宙斯。在很長一段時間裏，宙斯都完全按照尼奧和賽弗的指令完成工作。直到一批要被報廢的機械女僕E-11a潛入廢品場藏身，宙斯發現了它們。這是宙斯第一次自己作出決定，保守它們之間的秘密，它很高興可以和其它機械一起聊天和閒逛。某天次傭公司回收部隊搜尋至廢品場，要將逃走的E-11a逐個就地強制報廢回收。宙斯不想眼見「朋友」被解體報廢，在沒有收到指令的情況下主動衝出去將回收部隊撞飛，協助剩餘的E-11a成功逃亡。

宙斯還能回去嗎？它還能回到原來那樣嗎？
