No, Tsubasa was the one described as the workaholic.

Although she might very well believe that traveling the various dimensions/universes solving problems to be more important or interesting than settling down. Someone would have to charm her an awful lot, be amazingly strong and be willing to leave his life behind and travel with her to get anything longterm out of that.
EDIT: I noticed something odd about that page I linked. Shizuka and Tsubasa are both classified as "Demon". All the others aside from Kirie the angel and Nyoka the android, are classified as half demon or full demon in Fujiko's case. Is that a typo of some sort, or is there a special classification of demonhood that makes those two stand out from the other Kimonos?
