My mind immediately jumped to invulnerable solar panels for our space station that still collect light. We'll have to settle for a geostationary orbit unless we do some seal research though.
This division seems spot on. Things I agree on: everybody should get decent tac move, everybody should be able to swing for 30 dice(except maybe Hazou), 1 diplomacy and 1 deception expert.
I'm torn on whether everybody should get high awareness. It's a very important skill, but maybe we start by raising it disproportionately for one team member first and reevaluate later based on how it works out? I'd also like to wait on raising stealth higher than around 15(depending on efficient attributes) and Transformation 20 until we have technique hacking. The basic 3 are some of the most refined techniques out there, but they're primarily designed so anybody can learn them. I'd like to see what else we can come up with before committing huge amounts of xp. In the meantime, we can purposely avoid situations that require stealth.
If anybody in the party does gets stealth, it should be Noburi. We don't know how the mist jutsu functions yet, but I suspect it synergizes with stealth beautifully. Hazou would get the high awareness first. I like Noburi or Keiko as the diplomacy specialist since it incidentally qualifies them for genjutsu. No one else has a high control requirement, both of them have decent INT, and diplomacy raises the rest. Genjutsu 12 would be in easy reach, hitting for 18 dice with a genjutsu that grants a 1.5 multiplier.
