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

Humanity might've triumphed over the aliens, but that didn't stop struggling space vermin exterminator Sumire Ichigaya from getting abducted by a UFO! After being implanted with a foul-mouthed extraterrestrial entity, she's got a lot more to worry about than just paying her bills!

After Duskin is asked to take part in the merciless testing of Sumire's abilities, a sudden attack of conscience pits him against Kiyoharu in a seemingly unwinnable battle. But when the battle between the clearly-not-just-an-accountant and the varmint is interrupted by the arrival of a deadly new enemy with her own devastating powers, will Sumire discover the strength she needs to fight back?
