Nabiki waited for Kasumi at the kitchen door. This way she could keep an eye on the people filtering in after the 'Lets chase Happosai on his weekly panty raid.' she also had the added benefit of being able to complain to Kasumi, without interrupting her while she prepared the snacks for the guests. The resource draining leaches and sources of income all rolled into one package.
The first to make it back was her younger sister Akane along with her fiance, Mr. Chaos magnet himself Ranma Soatome. They were followed by two young beautiful girls. Big surprise there. The man could attract beautiful supermodels to him just by breathing. Then piss them of the moment he opened his mouth. The boy had the social skills of of a spider monkey, possibly even less. She didn't have the time nor the inclination to experiment. Maybe later, when she had some free time and minus the bottomless pits she had to feed.
The rest of the Nerima Wrecking Crew showed up soon after, with Happosai and Cologne bringing up the rear. She kept up a running commentary about who came in and in what condition. It not only amused Kasumi, it was also a form of triage. If it was something Kasumi could treat, the first aid kit would come out. Otherwise it was a quick trip to Dr. Tofu.
What she didn't know, was that her commentary had more of an audience than just her sister Kasumi. Both Xander and Barbara were listening in with their superior hearing. This was a gold mine. The girl had a sharp mind and her description was telling and precise. Names matched to faces, along with comments about each person. A brief synopsis if you will, about what appeared to be a group of highly trained Martial Artists.
Xander glanced at Barbara, she signed that she was indeed keeping track and files were already created about everyone in the compound. This was where real power was created. Bits and pieces of precious data painstakingly gathered, or in this case freely overheard over the rising chaos generated by all the hormone driven teenaged Martial Artists.
She had already witnessed several confrontations between what appeared to be a group of super powered teens. They jumped around like jack rabbits hopped up on speed. They easily cleared fifteen feet or more in a single jump. They shattered rocks and concrete with a single blow and in some cases a young man in a kendo uniform shattered a reinforced rock and concrete wall with his head. Before she could react or rush to his aid, he got back up on his feet, a little dazed perhaps, but he still got up under his own power. He then drew his bokken out of nowhere and started to spout bad Shakespearean poetry. He somehow manged to call down lightning out of the clear skies. She tagged him as a latent meta human-untrained. The lightning strike was several miles away after all.
The Chinese Amazon tribe delegation was a know factor. The rest were about as bizarre a collection as any meta human gathering she had documented in her files. An unbalanced gymnast in a purple leotard, with with a minor telekinetic power was twirling a ribbon surrounded by cloud of black rose petals laughing insanely. She overheard the teen, Nabiki identified earlier as Ranma Saotome call her Petunia aka the black rose. That didn't make much sense until she heard Nabiki identify her as Kodachi Kuno the sister of Tatewaki Kuno the kendoist. She could smell a virtual cornucopia of mind altering substances wafting all the way from the other side of the garden.
A large teen of rough appearance, wearing a sturdy yellow top and black pants carrying a large red bamboo umbrella was casually fending off the blind Chinese boy Mousse while talking with Kasumi's sister Akane. The Male Amazon sent a virtual thunderstorm of sharp edged weapons at the Man Nabiki identified as Ryoga Hibiki and who Ranma nick named P-Chan. Mousse the 'Obviously blind as a Bat.' teen had his glasses at the top of his head. He was shouting something about Ranma stealing his Shampoo. Had she not know, that Shampoo was the rude waitress and not a hair product, she would have thought the nearly blind teen was homicidally insane as well. 'All he probably sees is a red blur. I wonder why he doesn't put his glasses back on? They are at the top of his head after all.' she thought.
Ranma started to tease the large muscular teen by calling him P-Chan and piggy. It started a three way argument that quickly escalated into a fight between Ranma and Ryoga. Ranma threw hundreds of punches at Ryoga at super human speeds and the sturdy teen soaked up the damage and blasted the ground under Ranma with a pointed finger. Barbara saw with her mage sight that the finger had an energy charge of some kind. While Ranma's entire body was surrounded by a very faint blue aura. The fight ended when a red glowing Akane punched Ranma hard enough to launch the teen into LEO.
"Xander!" shouted Barbara.
"On it!" shouted Xander. He shed his shirt and went after the rapidly rising teen.
Everyone and everything stopped as they saw Xander take off after Ranma.
Outraged at the deadly assault. Barbara charged Akane. With a single leap she reached the angry girl. Before she could do or say anything, Cass-y-D intercepted her. Cass-y-D knew what Barbara though and what she was about to do. She reacted without consciously thinking. She just knew, that she had to stop her surrogate sister from making a huge mistake.
"He's fine! She didn't even injure him." she said quickly.
"What do you mean? Did you see how hard and far she launched him?" Barbara asked.
"Yes. Yes I did. Scary isn't it." Cass-y-D told her. The only one who might be even more durable than the fastest mouth in the east is the cute muscle bound lump over there." she said pointing at Ryoga.
"No. No. No." A red faced and tongue tied Ryoga tried to refute the charge, but the girls just ignored him.
Barbara didn't say anything. She carefully analyzed all the pertinent data at hand. The boy was superhuman. Super speed, strength and durability. A low level force field. The casual use of lethal level force by everyone she had witnessed. The fact no one reacted to the assault on the boy, but they did to her when she charged the violent girl.
"Such a violent girl. Akane, Shampoo make you pay for hitting Airen." Shampoo said with a wave of her colorful mace.
"Not now Shampoo. Son In Law should be fine. Although, I still don't know why he keeps letting her hit him like that?" said the Amazon elder.
"Did you hear that Soatome." said Soun Tendo.
"Indeed Tendo. We must move our wedding plan up as soon as my son gets back." said the wet balding middle aged Martial Artist.
Together the two fathers pronounced their plans out loud. "It's Soun and Genma's operation get them hitched while they're arguing."
Everyone of the Nerima residents did a minor face fault.
"Idiots!" Akane said looking at the two oblivious men.
Her sisters just nodded, silently agreeing with her.
While everyone was waiting for the two middle aged men to come out of their shared fantasy, Xander came down carrying Ranma with him. They landed on the roof top. Ranma immediately jumped the three stories to land beside Ukyo Kuonji, his cute fiance.
"Ranma honey! Are you okay?" Asked the vivacious brown haired "Pizza Ninja Babe."
"Hun. Oh sure U-Chan. Never better. Xander san here gave a lift on the way down." Ranma told her pointing at Xander, who just retracted the wings on his Nighwing suit. "So Xander san. Is it a deal? You teach me how to fly and I'll teach you the Saotome secret techniques."
"Deal." agreed Xander. "What are the secret Saotome techniques again?" he asked.
"Let's see, there's speed, invisibility and vacuum generated blades." Ranma answered.
"Sweet." said Xander with a smile.
"Who are you people?" Akane Tendo asked rudely. She was on the verge of throwing one of her monumental temper tantrums.
"These are guests Akane. This is Richard Alexander Grayson and his fiance Barbara Gordon. He's also my new fiance as well. Father, uncle Genma and his father were students of grandfather Happosai. It seems you weren't the only one who's future father was thinking about. Aren't we lucky to have such a thoughtful and considerate father Akane."
Not a single person who heard her speech thought for a moment that she didn't mean every word of it.
"Lucky's not the word I'd use Kasumi." Akane said with a sad sigh.
