Happy Kanako's Killer Life Vol. 7 (manga)

People will tell you that mixing love and work is a bad idea. And when you’re a killer for hire, relationship drama can have especially deadly consequences! Kanako finds herself in a guns-drawn confrontation with a bunch of her fellow female assassins. She may have a notorious reputation in the underworld as the most dangerous up-and-coming hitman around, but that didn’t prepare her for a battle over a man’s love!
