Kaoru reunites with Reiko and Kyoko, and the trio known as KKR is back together for the first time since their previous lives! Kaoru's goal is the same as ever: to save unfortunate children, teach them to support themselves, and punish evildoers as a defender of justice(?)!  The three girls use their cheat powers to make the world a better place...but Kaoru's also planning to use her potions to survive and live as she pleases!
