Pretty neat, though I still have a few points.

How can Kintaro not know what an okonomiyaki is?  Aren't they relatively
common in Japan?  He's no foreigner, so I'd think that he'd know.
Okonomiyaki is should be lower-case when it's not at the beginning of a
sentence.
I sort of wonder why Kintaro is offering his services?  What's his
motivation? Haven't seen #6, but in all the other eps, it's to learn.
Well, he's already been in the resturant business, so it's hard to see
what he can learn here.  In fact, I would think that he would lean more
towards the noodle business, since he knows how to make noodles.

Should you write it?  Why, of course!

The sardines weren't worth the trouble.  A few more shots, then 
Ryoga-san would overheat and explode.  Ducking around a corner, 
I managed to lose him as I entered the ramshackle residence of 
my Anime supplier.

One look at his face and I knew that I was betrayed.  "Tell me."
I insisted.  He refused, so I slammed him against the wall.
"Last chance.  Where can Ranma-Ranma find good fanfics?"
"Try Jason Liao." he whispered, before he slumped to the floor.
I heard the sounds of a door splintering as I left through the 
window, one step ahead of Tendo Heavy Industries...
