Etymology: Derived from Japanese elements: 'ri' (理) meaning 'reason' or 'beauty', and 'ona' possibly being a phonetic rendering of 'umi no hana' (海の花), meaning 'flower of the sea'. Alternatively, it may be linked to 'ri' (莉) meaning jasmine, combined with 'na' (奈 or 菜), giving a floral-sea hybrid imagery.
