adding my train of thoughts in the similar vein.

The kana, ゼノヴィア, is read "Zenovia". I suspect that Ishibumi actually meant it to be identified with the famous Greek Queen Zenobia, but intentionally used the modern form (well, let's face it, the v spelling sounds cooler than b. However, not even all western readers are familiar with the modern form [except perhaps the Greek readers]. This caused a bit confusion to me when her son's name, Zen, is revealed. In this sense, his name should be Xen instead of Zen, but that would lose its dual-meaning nature).).
