Rai Rai Rai, Vol. 4

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!

All Sumire wanted was to enjoy her day off! Koharu, a young woman with powers similar to Sumire’s, is back and ready to join in the fun, but her handler’s a hotheaded thug who’s itching for a fight! With the threat of an all-out brawl building, there’s only one thing Sumire can do—settle matters with a brutal, no-holds-barred, winner-take-all game of mahjong!
