Ok, reviewing the payment line.
[] Note that you're not interfering with Sendai's payment, but that such payment is entirely Sendai's prerogative. Whether Sendai wants to charge a penalty for the damage Fukushima caused is their business.
Since this is immediately following up on the chewing out, it should already be clear how we feel about the whole thing. So the tail end of the above line is a bit redundant, particularly the aspect of our own feelings on how the payment should be handled. At the same time, as noted, it could be far too easy to misinterpret our set-up as an explicit demand.
I am trying to comment on the payment that Yumi makes (or does not make) as being her own choice, not something we're forcing one way or the other. At the same time, I'm trying to get Yumi to actively think about what she does, as a leader, not an interim leader who's just going through the motions of past agreements. That is, do what needs to be done, not just what she thinks Akiko wants her to do.
That can't just be assumed if we let things pass silently. The act of bringing it to people's attention means that everyone will pay attention to exactly what Yumi does, and she will likewise be aware of that attention.
Possible revision:
[] Note, though, that their agreements with Sendai are their own business, and how Yumi wants to handle that agreement is her own choice.
