Making my own write-in, with my preferred wording for the tax question and no Chika question (if it's important, it'll come up in response to the "what else has she done" question)
[x] Please don't ask for help yet. Let me try to stop this whole conflict first, and yes that includes Akiko's "tax". It's best if neither group escalates anymore; Akiko's got plenty of favors to call, so she'll match you girl for girl.
[x] This 'tax'... How exactly does it work? Were you offered anything in exchange, and how did she approach you to demand it? I've heard about some of it from others, but I'd like to get your perspective.
[x] Does Hamasaki just want you all out of Sendai? What did it take for Fukui to leave? Was she wore down by Akiko's... Policies, or was there a breaking point, too?
[x] What else has Hamasaki done?
[x] Once that's done, ask if they would be able to talk their minds with Akiko at the table. In addition, would they be willing to discuss things with other members of Hamasaki's group there? Mind that any agreements will hold more weight if it's done in person and not through an intermediate.
