Hello!Pro Kansai Debuts as SI☆NA (Some Boys! Blog)
H!P Kansai no Longer Trainees (Just Another H!P Blog)
Recommended reading. Taking a cue from the considerably more successful Johnny’s collective, Hello!Pro Kansai are now an official unit whose name is taken from the first initial of each member. Their actual activities – music releases and touring, for example – are apparently undetermined.

This is in addition to Happy! Style? Or that was never H!P?

Both Happy! Style and SI☆NA are under H!P, but the Kansai girls are debuting as their own unit separate from Arisa and the two trainees.
