There are two characters named Enzo appearing in Bayonetta and Devil May Cry. Both characters support Bayonetta and Dante as an informant. There is proof that both Enzos are the same person.

In the Bayonetta art book, there is a picture of Enzo playing poker with someone while Bayonetta and Rodan are in the background. Enzo's opponent is shown to have lost a sword, two handguns, and a red coat. These are all trademarks relating to Dante. This not only shows that the Enzo that helped Dante was the same Enzo that helped Bayonetta, but successfully connects the Bayonetta series to the Devil May Cry series.
