I've arranged seven single panels from a semi-random selection of duels that Usagi has fought over the years. What I'd like to know for each image is:
- The name of the story* the duel appears in. (Including part or chapter if applicable)
- The page number of the story* the panel appears on.
- The name of Usagi's opponent in the duel.
In descending order - top panel first, etc.
* I won't be too much of a stickler about issue numbers and the like, since I'm getting these from reprinted collections myself. On the same note, 'page number' refers to the number that Stan places in the corner of each page, rather than collected edition page numbers.
Here are the panels:

As usual, PM me with your answers. The winner will be randomly chosen from all who provided the correct information, on Sunday 18th December, and will receive a copy of Samurai: The (Unofficial) Japanese Warrior's Manual by Stephen Turnbull, from my bookshelf (and yes, it's supposed to be yellow at the bottom!):

I hope that's all satisfactory. And away we go!
