The most interesting part of this chapter is the fact that the Royal Guard have to use the Shiba cannon to get back to the Palace. We know that the Shiba clan was once a 5th Great Noble House and fell. With these houses they seem to serve some powerful or influential role. Kuchiki are librarians and/or historians. Shihoin are treasurers or seem to guard many valuable and powerful items I would go so far as call them bankers but for artifacts rather than money. Perhaps the Shiba acted as transporters for the RG(still do) and the royal family at certain times and this led to them rising to being a Fifth Noble House. Being that they specialize in fireworks, maybe they also had a hand in ceremonies at some point in the past.
