Well done.
Here are a few things that I noticed that merit your attention:
Shampoo and I aren’t that good, but we can use it to reinforce our mussels.
muscles
Ukyo pulled a dented combat spatula off the mass of red hair, and watched Shampoo pull her dress up slightly. She gave the Amazon a grin. “Lets get that cut sewed up before he comes to.”
No need to change anything here. It just occurs to me that Ukyo and Shampoo might have to work quickly to staunch the bleeding with Ranma no longer being able to control his muscles to restrict the blood flow.
Jeeves walked down the hall of the motel, the rescued prisoners following.

They were a way of marshaling ones thoughts, putting a barrier between their thoughts and the outside world.
between thoughts (you have they and their in the same sentence refering to two different things.)
“No, Tofu disappeared before long. I still wonder what happened to him.” She grinned. “I think grandmother had her eye on him!”
“How old was he?” Ukyo asked tentatively.
“About 30!”
“Gak!!!”
Gak!! ( has distrubing image of Cologne holding Tofu captive in basement of Nekohanten.)
The only ways it differed from something you would find in the local police station were the NO2 sprayers and the hidden cameras. Well, that and the manacles on one wall.

In fact, it would only work in America, Australia, and Europe. It’s called a ‘Road Trip’.”
Those poor Canadians having to rely on dogsleds and canoes to get from place to place
Opposite me, a woman with more wrinkles than most retirement villages rubbed her chin thoughtfully.
Nice imagery.
I snickered to myself. “He tried to hit me for loosing his chance to get cured about an hour ago, then got splashed and trotted off for water. Haven’t seen him since.”
losing
The chef froze in place. “Yes?” She sounded really nervous.
It sounds odd, as Ranma is narrating at this point, for Ranma to call Ukyo "the chef". perhaps, as you have further down:
My cute fiancée
I held up my hand. “I don’t care if he shot you in the head or badmouthed Onomyaiki. Just stop doing it!” Ukyo looked down ashamedly.
“Yup,” I sighed. “In school, people would occasionally say in passing that they didn’t like Onomyaiki, or that he was pretty gay looking. It never ended well.”

They weren’t trying to beat each other to death any more, but they still argued a fair bit.
anymore
She looked at me with amusement. “I could buy myself a country, and barely effect my bank account at all.”
affect
She looked blankly at me. “Ucchan loves Onomyiki as much as she loves me, and Shampoo’s almost as bad with Chinese food.
I took them as she finished with each one. Ucchan cooking her very first Onomyaiki. A close up of the Onomyaiki. A picture of me, guy form, eating an Onomyaiki, and another of me as a girl eating one. A picture of her shop at Nerima. Another picture of an Onomyaiki.

It was one where Ucchan tried to combine her two great loves- Onomyaiki and me.
Okonomiyaki (you might want to run a spell check to see if any were missed.)
There you go!
