Why didn't Hayase's Nokker control her like other Nokkers did with other humans?


All other Nokkers which attacked humans controlled them. But Why Hayase's
Nokker didn't, instead it coexisted with her. Why did this happen?




It's implied that this specific Nokker was different from the rest of it's
species for some unexplained reason (given that it appears to work against the
other Nokkers in one case), and developed a desire to follow and aid Fushi.
This lines up with Hayase's goals and it likely decided it could achieve that
goal more effectively by coexisting with her (and her lineage).
