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!
