Okay, I've not seen Tenchi Muyo (The actual series) for the better part of a decade, so don't get pissed if I mess something up, but...
----------
The majority of the Masaki household stood, nervously, on what they assumed was one of the resident scientists new devices. Now, while this would normally be nerve wracking enough, there was one thing that made this worse...
The device Washu seemed to just be a big chunk of wood with some stuff carved into it.
The only comfort was that she was standing on it with them, waiting for something, so they could be somewhat sure it was mostly safe...
Mostly...
"Would you please tell us what the hell we're waiting for?" Ryoko asked, quickly getting angry that they had been standing for almost five minutes.
Checking a nearby clock, Washu clicked her tongue, "Yeah, I guess we've got a couple minutes before it kicks in, we're going to a family reunion."
One could hear a pin drop as everyone else standing on the large circle of wood stared at Washu, just their looks asking for more information.
"Well, Long story short, I once ended up in this other universe or reality or something, and got married into a ninja clan, then some experiment went wrong and I ended up back in this reality." Washu explained with a shrug.
Again, silence, but this was broken by Kiyone, "Okay, I think we should be told more."
Washu sighed, "Well, there was some accident on the clan island, and most of the clan got scattered across time, space and multiple realities. The last son of the main family line recently reversed it, so the clan's been pulled back and we're getting a family reunion. Since Ryoko is my daughter, she's technically part of the clan. It'll be fun."
"Uh, and the rest of us?" Tenchi asked tentatively.
"Don't worry, I have a plan."
"Well, I do too," Ryoko groaned, "I don't see why I have to go to some boring old gathering for a family I've never met."
Washu smiled, "Oh, trust me it'll be fun. Last party I had with the Uzumaki clan was in celebration of the Clan Head having a daughter," Her smile turned devious as her daughter floated away, "It lasted three days, consumed three times the clans total weight in alcohol, caused countless amounts of collateral damage to private and public property, and ended with an enemy island nation being sunk into the ocean."
In the blink of an eye, Ryoko was at her mother's side with a big smile, "Well, what are we waiting for? I can't wait to meet my family."
The others, however, were now even less optimistic about the chunk of wood, but it proved too late as the symbols began to glow. With an odd feeling passing through their bodies, they suddenly weren't in the lab...
And they suddenly had a tall, one armed, red haired man smiling at them.
"Auntie Washu!" The man greeted joyfully, putting a hand on her head like a child, "You've gotten shorter."
Washu answered with a solid punch to his gut, "And you've gotten as freakishly tall as your dad, Shanks, you little brat."
Chukling and holding his gut, Shanks smiled, "And who is this with you?"
"Oh, this is my daughter, Ryoko," she introduced, before motioning to Tenchi, "Her husband Tenchi-"
"What!" There was a chorus of cries as Washu continued.
"-And his other wives, as well as his little sister in law."
"WHAT!"
Instead of any reaction they would have expected, Shanks just smiled, "Well, then welcome to the Family."
"WHAAAAAAA!"
