Remember how the Tsukumo sisters were directly created by the Mallet incident (probably accelerated the 100 year cycle), and found another power source with Raiko's help (Raiko is a tsukumogami drum who got a modern drumset and outside world magic (whatever that means, magic there hasn't been the same since science))?
So the question here is, what would you imagine a modernized Benben or Yatsuhashi be like if they got another instrument from the outside world? What would be their new instrument? Will they wear shoes? How will their clothing style change?
Yes, I know canon will screw me over because the Tsukumos already got a new power source (but why are they using the exact same instruments in the extra stage then?), but I like thought experiments.
