Nabiki dressed in a hurry the next day and ran out of the house after wolfing down a quick breakfast. Today was going to be a fun day. She smiled to herself, she had a lot to do. She hummed happily as she ran to school.
Ranma arrived alone at the gates of the school about a half hour later. She smiled to herself as she saw him arrive, he was right on time for his usual schedule. She was surprised that Akane wasn't with him, but she had to admit that she wasn't sad about it.
Ranma nodded politely to her as he entered the gates and headed towards the school building. He was playing it very cool. She smiled back at him in return and let him pass in silence. He twitched at that. Oh yes, today was going to fun. She always enjoyed taking people out of their center, especially powerful people. With Ranma inexperienced with the ladies, it would be easier than usual to do that, but it wouldn't be any less fun. She smiled to herself as she began to follow him. It would only be a matter of time now. She could already hear the commotion starting as students called out to themselves about the news.
"Hey did you hear?"
"What?! Ranma and Akane split?!"
"I hear he switched to Nabiki!"
"Wow... an older woman!"
She couldn't help herself, she knew she was grinning. Some of the students noticed her walking behind him, and ran up to ask her to confirm or deny the news. She happily handed them the flyers she had made last night, without speaking, as she continued to follow Ranma and smile.
Akane arrived at a full run at that point, but slowed when she saw her following Ranma. As Akane reached her side, she teased her. "I wonder how they found out?" She continued to hand out flyers to the students who approached her, with a straight face.
Akane wasn't in a joking mood, though. "Gosh, could it be because..." Akane trailed off, in an annoyed tone, and just pointed at her as she continued to hand out flyers.
She simply smiled. To herself she thought, Any minute now...
"Akane! Come! Leap into my arms!" Kuno yelled at the top of his lungs, with a rose clenched in his teeth, as he appeared from nowhere and lunged at her sister. It was uncanny how he was able to do that.
Here we go. She thought smugly to herself as Ranma leaped into the air as Kuno lunged. Her eyes tried to follow him as he moved, but he was just too fast.
Akane danced back out of Kuno's range and yelped, "K-k-kuno?!"
"Mornin', Kuno." Ranma said nonchalantly as he landed on Kuno's head and glared down at him. 
Kuno, to his credit, simply stood up and brushed Ranma off his head as he smoothly pulled the rose from between his teeth and handed it to Akane. He then turned to grasp Ranma's hand with a friendly smile plastered on his face. "Good morning, future brother-in-law!"
Ranma recoiled at that. "Hey, who're you callin'—?!"
She took the opportunity to remind Ranma of what had happened last night, she quickly stepped forward and looped her arm through his as she spoke to Kuno. "Oh, yeah...that's right..."
Kuno reached over and wrapped his arm around Akane's shoulders as he smiled in a way he probably thought was magnanimous. "Yes! Brother and sister-in-laws! Akane will be mine!"
Akane was twitching in anger. She leaned back a bit to make sure she didn't get hit in the crossfire of what was coming. Akane smoothly slipped Kuno's arm from her shoulders, pivoted her hips, and then kicked him so hard that he sailed away across the courtyard. Many of the guys in the school cheered and whistled as she did so. They not only liked watching Kuno take it in the teeth, but they also enjoyed seeing Akane in action.
As Akane calmed down, she leaned over and pulled Ranma behind her as she taunted quietly into Akane's ear. "Akane ... admit it. You want Ranma back, don't you? Act now and I'll give him back for five thousand Yen."
"I'm not for sale!" Ranma protested.
"I don't want him!" Akane growled as she turned to her and again denied her claim to him. Akane then turned to walk away in a huff, but paused and looked over her shoulder. "Since you have decided to tell the whole school about this, just one word of warning, Nabiki ... if you're going to be engaged to Ranma ... you'd better do some training." Akane walked away quickly after that, as she hurried to class.
"Huh? What do you mean?" She called after her little sister, but Akane didn't respond. She looked up at Ranma who shrugged.
Her mind was churning. What did Akane mean by that? Is she just trying to confuse me? Is she threatening to fight me for Ranma? Ranma interrupted her train of thought.
"Um ... Nabiki?" He asked nervously.
She simply looked up at him, annoyed at the interruption.
"I-I need to get to class..." He said, as he looked down pointedly at his arm. She realized that she was still holding on to him. She smiled sweetly at him and released her grip. He took a couple of hesitant steps away from her, unsure of what to do, so she shooed him towards class.
"Well, go on, you'll be late." She added, to get him moving. He nodded sharply and pivoted on his heel and dashed off towards the school building running at an incredible speed. Instead of entering through the main doors, though, he jumped up into a nearby tree, and then into the window of his third floor classroom. She had to admit, he was good. She hummed happily to herself as she walked into the school building while she pondered what Akane had meant about needing to train.
She was sure it was nothing but Akane trying to rattle her.
