I think that Sembalence are constructed out of aura which can appear like the user is expending their aura to power sembalences.

An example following the above:

Ruby's sembalance predominantly uses arua's repulsive properties in tandem with newton's third law much like how she launches herself with Crescent Rose. It however is important to note that Ruby can also use the same ability on things around her, accelerating the light items toward JNPR in the first episode of season two. Finally I think that because weapons are infused with the user's aura that the Crescents Rose's round ejection speed may be connected with this as well.
