There is nothing "only" in any of our Oni information.

We know how they were summoned during the episodes we saw.

We don't know how if that is the ONLY way to do it.

We don't know, for instance, how they were summoned to kill the yakusa with Young Chris Argent.

While it's not explicitly stated and therefore NOT CANON - it is assumed by most that the figure at the Nemeton was Noshiko Yukimura.

They used a stand-in named Tyler Schnabel to actually film that scene so none of the cast actually pulled the sprig.
