Humanity mightve triumphed over the aliens, but that didnt stop struggling space vermin exterminator Sumire Ichigaya from getting abducted by a UFO! After being implanted with a foul-mouthed extraterrestrial entity, shes got a lot more to worry about than just paying her bills!
Following an explosive accident, Sumires new life working for the Raiden Corporation has hit a bit of a road bump! Now, with her team stuck in the contaminated ruins of old Tokyo until she gets her transformation under control, shes going to master her strange new powers (and get a raise in the process) or die trying!
