So our team knows about the psuedo-date plot, the Tannagi Elder knows about said plot, and our village allies probably know about it too.
...
Did anyone tell the love-struck psychopath her crush is doomed to failure? This seems like a critical error on the part of the plotters unless her not being in on it is a part of their real plan. We need to get all of these clever people in a room with Yuno and then tell her what the plan is. If she goes nuts, the village can disavow and/or put her down as needed. If she is cool with it, we can proceed as planned.
We also need to think of a way to break off this marriage if they try to pull a reversal on us, like
@Pahan and
@MadScientist noted. Could our team also act as though we disapprove of the arrangement, or is it too late already? Maybe we could claim Noburi has some sort of physical issue that would cause issues later on in the marriage? We can't let the village keep dictating how our relationship develops; if we do not assert ourselves in some way soon we will end up as their pawns, rather than as their partners.
I think now is a good time to start introducing any villagers (after they pass a background check from ourselves and our political allies) to our culture (in a secured yet public area for Kagome's sanity's sake). Just like each clan family in the village has their own characteristics, so too do we need to differentiate ourselves lest we become divided among the clans. We should still interact and mingle with the clans, yet we should retain some form of our outside identity otherwise we will never leave this village with friends. Ideally, we need to position ourselves to be the village's primary source of information of the outside world as well as a guide of sorts. Every time the village wants something from the outside world we need to be able to placate them to continue earning their trust. With our storage seals we can smuggle virtually anything undetected into the village, be it new renewable crops for a better source of nutrition, a new design of forge for better steel production (I'm assuming they have some form of metallurgy since they have kunai), to new forms of entertainment.
Reaffirming to our political allies that we do not seek total integration will take some serious politicking, but we do have an edge: knowledge they want. The Takahashi have already benefited from our outside knowledge of new techniques; we should endeavor to assist our other ally in a similar way. The Yoshida already know that Hazou has an interest in sealing; why not have him exchange basic seals with them while keeping Kagome as our ace in the hole? We might learn something new
and ingratiate ourselves to them at the same time.
By explicitly showing our allies that associating with us benefits them immensely, more people should logically want to associate with us as well. We can defer to our original allies whom we should entertain as a sign of favor; the sooner someone aligns himself with us, the better his reward(s). All we have to do is propose such a plan in the presence of both elders; if we favor one over the other at this point in time we will only weaken our position. Furthermore, favoring one over another might be interpreted as a betrayal by the other.
I think we are in a safe enough position to start testing the tolerances of the agreement we made with the Takahashi and the Yoshida, so long as we step carefully and advance slowly yet steadily.
