PSA:
Clan finances
Note: $1 = 10 ryō, but the following numbers are all given in dollars for simplicity:
You have $100,000 in the clan reserves, plus the $40,000 you earned while gambling in Mist during the Chūnin Exams. Your monthly expenses are $400,000. You will receive one more payment of Pangolin blood money in the amount of $520,000.
Most of the clan's money is physical coins in the clan vault under the house, with a small amount being in the form of open accounts with various businesses (grocery stores, etc) around town, just to simplify shopping.
These numbers are chosen somewhat arbitrarily but we think they are plausible. We don't believe there's been enough information onscreen to come up with more precise numbers, but if anyone wants to do textual analysis to figure it out then we're happy to listen. Note that there is a substantial amount of flex in how much money was coming in and how much was being spent on the search for Naruto, bribes, etc, so we feel justified in moving the "cash in the bank" number around freely and we are inclined to keep the balance at roughly 2-3 months of runway. It's enough that you're not completely screwed by the loss of your only income stream but also not so much that you can afford to sit around.
Keiko's departure
Now that she is married into the Nara clan, Keiko is no longer primarily a Gōketsu in the eyes of Leaf's laws. She will not be living at the compound, although she is likely to come back to visit at least sometimes -- how soon and how often will depend on upcoming events re: the family's reaction to the cessation of the Pangolin deal.
Regardless of what happens, she will not be able to function as Clan Treasurer anymore. When you ask around you will find that Akane and Noburi know absolutely zero about accounting and are terrified of even trying. Mari has enough experience to read a ledger as part of her infiltration training, but definitely not enough to do the job of actually managing accounts. Kagome has no experience at it but is fascinated by the idea and was poring over the books and scratching his head within an hour of Keiko leaving the house. He's going to ask her to give him some lessons as soon as time can be made; he's not averse to the idea of trying the job but he's nervous about whether he can actually do it. You do not know of any civilian accountants, although you could look if you wanted to.
Things that happened offscreen on Sunday and Monday (the wedding was Tuesday)
Noburi found the rules for adoption into a clan. It's pretty straightforward; you just have to file a public statement with the Tower so that it can be recognized to have happened. It's less a question of approval and more a question of that being a good Schelling point for public record keeping. Based on the number of records and the dates on them it's very clear that adoption happens but it's uncommon. Reading between the lines, Noburi suspects that doing it too often will piss off the other clans. After he was done with that he talked to Akane for suggestions on talented clanless ninja who might be good candidates for adoption. He has a list of names to investigate but not nearly enough information to make a recommendation.
Keiko mostly spent her time reading the family ledgers and getting them tidied up to the point where someone who isn't Jiraiya could understand them. When she wasn't doing that or other onscreen stuff she was "training" with Tenten.
Mari was out and about. When asked what she'd been up to she was helpful, responsive, and completely uninformative.
Akane was mostly training, getting her stuff moved, and helping her parents sort out the business plan for the expansion of their family business that will be based on the promised Gōketsu investment money.
Kagome was making seals and improving the defenses when he wasn't at the library or studying the clan finances.
