Miru Eru

An engineer in the Giftia maintenance team, who has been on the job for only two years. She is also an "android geek" who particularly dotes on Isla. Her friend, a Giftia named Olivia, was retrieved years ago, but had her OS replaced and is now living a new life as Terminal Service No. 3 marksman Andie, much to Eru's initial dismay.
