Implanted with an extraterrestrial entity, a former space pest exterminator battles deadly alien threats—all to pay her bills!

Sumire Ichigaya’s got it tough.

Sumire’s new life as a member of the Raiden Corporation is underway! But if she’s going to survive her new life as a space vermin exterminator, she’s sure got a lot to learn—like how to control her mysterious transformation ability and how not to drive her new roommate crazy!
