History
Terumi is a legendary figure who is said to be related to the eventual activation of the Keruvim and the fulfilment of its purpose. When Klak approached Zev Raregroove to tell him about a code he had found, Zev recited a legend about the Keruvim: "The Angel's heart shall commence, when Terumi awakens. All that the Betwixt and Between began, shall end". Zev then sent Klak and Prudence to an isolated world to find something that might help them in their quest to decipher the code. There, Klak encountered Akzer and discovered the truth about the legend (though what this "truth" was has since been lost).

Terumi was apparently an enemy of Naju.

In 150,082 CMT, Kokonoe told Iron Tager that she was going to send her "Subject" into combat because she didn't have much choice with "lunatics" like Terumi running around, implying that Terumi was already awake and active.
