My Theory:

Haruno Shiobana (汐華 初流乃)

-> Ha-Ru-No (初流乃) Shio-Bana (汐華)

-> Sho-Ru-No Shio-Bana*

-> Gio-R-No Gio-Vanna

 * "初" can of course be pronounced as "ha," but this is actually a very rare case.

In general, it is pronounced as "Hatsu" (First-Ever), "Ui" (Fresh) or "Sho" (First/Early), I guess.
