I Shall Survive Using Potions! Volume 9

Times may have changed, but not the trio of girls known as KKR! Kaoru, Kyoko, and Reiko have punished Roderich, the arrogant and corrupt Relinas Trade Company branch manager, and he’s now looking to get back at them—both overtly and behind the scenes. Kaoru’s solution? To crush Roderich and his gang before they can get to KKR, of course! With justice(?) in her heart, Kaoru shall survive another day and continue vanquishing evil!
