I think you'll have a much, much easier time grinding for Juzumaru in 7-4 compared to Kikkou in 7-3 as long as you only take high level regular (not kiwame) tantous with you so that you'll always enter the super easy long route instead of the much harder medium/short routes. Not to mention you are 100% guaranteed to reach the boss node in 7-4 every time you go there and with the doubled drop rate campaign you should be able to obtain him quite easily as long as you can consistently A-rank the boss node (which may occasionally inflict serious injuries on one of the tantous depending on the enemy formation).

As I said earlier, it is much harder trying to drop Kikkou from his regular map in comparison (unless you get really lucky) due to the high difficulty level of the map as well as all the annoying dead end nodes that make it frustrating to reach the boss node in the first place. If you didn't manage to get Kikkou by the end of the campaigns I suggest exchanging your seals for him then (and only if you don't want any of the event-exclusive swords instead).
