New Wraith Designs?
These things in the trailer are either wraiths (who got a new design for the movie, or are modified in dome way), or maybe some wraith ripoffs by either Akumura or Kyubey, or someone else.
It also apears, that when killed these wraiths drop/leave behind these wierd ofuda-like things.
Note: In Japan, Ofuda is considered a talisman in Shinto and Buddhism, and Wraiths do seem to take a lot of inspiration from Buddhism.
Lastly, at this point they aren't even trying to hide the third (or first) new girl's connection with wraiths.
