Is there a significance in the names of the artificial spirits?
This is a community wiki starting point of an answer. Feel free to either contribute to this or append your own answer.


Shinku’s artificial spirit is Hollie. This could be connected to Ilex (e.g. Ilex aquifolium), the prickly plant with the red berries.
Hina-Ichigo’s artificial spirit is Berrybell. Potentially a connection of a ringing bell and a (straw)berry.
Kanaria’s artificial spirit is Pizzicato. This is a violin playing technique also referred to as plucking — fitting with the general violin/music theme of Kanaria.
Souseiseki’s artificial spirit is Lempicka. This has the same spelling as the Polish art deco painter Tamara Łempicka, although the katakana spelling of the spirit implies a different pronunciation. I don’t know if a connection exists.
