Regarding section 1, I think it would be best to put the wall of text in section 6 or 7 - at the end rather than the start of the plan, so the gm reading it isn't immediately overwhelmed. Instead repurpose section 1 to focus on the 2-3 innovations you think are most promising and why.
Some possibilities we could propose for section 4.2.1 -
1) Nara and J clans share Keiko; Shikaku and Mari both adopt her or something
2) Betrothal rather than immediate adoption / marriage
If the next update is supposed to be Shikaku summoning Hazou, probably want a contingency for that.
Hazou's General Disposition
*Hazou is earnest, but not energetically so. Does best to remain calm and professional.
*Willing to engage deeply on an intellectual level but understands that own ideas can be radical; will explain them in depth but does not become "preachy"
*Does genuinely believe in Leaf's ideals and is committed to ending the war quickly - and as bloodlessly as possible. Tie back into Yumehara's histories and other books if appropriate, but not in a tryhard or favor-seeking way: Shikaku will see through that in an instant.
*Do not accept any binding commitments, Hazou has to defer to Jiraiya / Mari on those
Likely Convo Topics
*How Nara & J clan can mutually benefit each other - Plenty of ways, Shikaku will likely have thought of more than Hazou. Just be open and honest here.
*Hazou's Ultimate Goals - From a zoomed-out perspective, Hazou's ideals should be relatively compatible or at least not strongly incompatible with those of most ninja. Hazou wants a world with less suffering & destruction and believes this can be achieved through better coordination, incentive alignment, and technological progress (increasing power of the species -> leveraging this power to reduce suffering). However, Hazou is not a hardline / calculating utilitarian nor does he believe blindly in the power of progress. A sealmaster as teacher has taught him caution for the power of technology.
I'm not really sure what Shikaku would want to talk about besides those things. He'll want to know how the Nara can profit from supporting J and whether Hazou is some kind of Mengele-esque supervillain, everything else should just be implementation details.
@OliWhail , Can we ask Jiraiya what Shikaku is likely to question Hazou on?
How much time do we have left to vote / revise plans?
