Anomaly

Sha, an Item created by Aldrich to save his Inventor's space, had become something elusive even to him.

Sha wasn't a Dreamer, Sha wasn't a Crawler, and Aldrich didn't know if he could call her a proper Item too. He had even made sure that the Sha hadn't turned into a pure elemental being, despite its tendency to become a Devil in the presence of Devil's aura. Aldrich, regarding Sha, had truly failed to find out about her nature. He couldn't find any better word to describe her than the words RECORD had used for her, i.e. an Unnatural Life form.

Sha was an Anomaly.

That's why, even if Aldrich had lost the ability to use weapons within the space of twelve pillars, Sha could use them independently.
