Sailor Venus shrugged her shoulders. "Is there some reason you shouldn't use your ki attacks against people who are harvesting ki?"
As soon as she said it, everybody present imagined Ranma's attack being hijacked and his ki drained away, leaving him near death and the Dark Kingdom having accomplished their goal in one shot.
Finally, Sailor Mercury said, "Perhaps we should ask you to stay as far away from our fights as possible."
"Sounds good to me," Ranma said just before walking away from the Sailor Senshi forever.
