All right, we've gathered a few chapter's worth of data on the Village Hidden in the Mountain. The more correct knowledge we can determine from analyzing them, the more of a diplomatic edge we will have. Here's my gathering of what I think relevant data is. I've drawn some conclusions from this, but figured it'd probably be more helpful to gather the information first, then post my own conclusions later. Here's my bullet pointed list of relevant information we've found out in the past few chapters about this situation.
Added
@Twofold's correction and addition, also Mari's analysis of their fighting ability.
Also apparently I can't read
Fixed comment about Akio being the beast lord)
Data points:
- Things Jiraiya's contact told us (chapter 33):
- Akio (the Beast Lord'd apprentice, likely summon scroll user) and the old blacksmith traveled through this pass to get to the city->village we shopped at
- Akio's master Ui defeated an invading army of ninja and civilians, which dispersed and settled throughout Tea, without Akio joining in the fight
- Things from visiting Tonaki (chapter 36)
- The village used to be a city, mostly full of artisans, but has been slowly decaying after the main road to them broke down
- The village had no records of note, and no rumors about Akio or ninja or summons
- Things from initial contact with the ninja (chapter 36)
- Have obedient Tapirs
- Use bows
- Didn't use ninjutsu
- Excessively hostile
- Relatively low combat ability
- Thought medic-nin were a myth
- Had vitamin deficiency and tape-worm
- Things from chapter 37
- They have one founder - singular (Hazou's deception check)
- Aren't comfortable sharing origins of their village with us
- The drugged ninja didn't react to Noburi saying Tonaki called them sacred guardians (though, he was drugged)
- They are guarding a scroll
- They've been working with the scroll for generations, but have had some kind of difficulty
- Keiko confirmation on Tapirs as highly-trained
- ~100 villagers, ~80% ninja
- Hunters, not farmers
- Regular close-range patrols
- Things from chapter 38
- The village keeps a watch on us ~2 dozen Tapirs and 8-12 ninja
- The village allows Noburi to heal people
- Their six year olds have combat training
- The non-ninja members are loyal and helpful to the village, but wish they could be more so, sad at not having chakra
- VHitM has seals (both explosive and storage)
- All these seals look like they came from same source
- Village is proud
- Kouta is not well liked
- Yoshida Tsukiko has authority and is used to being obeyed
- Our escort left us
- Kouta obeyed her
- She tried to order our team around (to varying success)
- Mari on their combat: excessively showy - likely haven't actually had to kill people for a while.
