"Well, it doesn't matter what technique principle I use as long as can successfully conceal my power, right?" Rui asked.
"That is true. As long as the objective is accomplished, the means are irrelevant." She nodded. "Still, with such a powerful mind, you are suited to learning mental techniques."
"I do intend to learn mental techniques as well," Rui remarked. "However, learning exclusively assassination techniques is quite important to me."
"Assassination and mental techniques have quite the overlap, you know," She twirled her hair. "It will be exciting to see what kind of assassin you become."
She smirked at Rui with a glint of interest. "When you do set out to assassinate the person you want to, be sure to invite me. I don't mind witnessing an incredible spectacle."
"I'll be sure to book front-row tickets."
"My, what a kind pupil. I shall do my best to be worthy of such affection."
