The commander of the Dvaraka, a ship like the Oceanus. Chris and Arque were originally under her command until they chose to transfer to the Oceanus. She also appears to have known Shizuno before she transferred to the Oceanus because Isola comments that her comrades on board the Dvaraka wish to see Shizuno again. After Shima, she appears to hold the most authoritative power within Celebram and is respected amongst her colleagues. Isola means "island" in Italian.
