>>12666064 Rei's first name means nothing because it's written in katakana and not kanji.
What? Just because it's kanji doesn't mean it doesn't mean anything. We don't have anything resembling kanji in English, but our names still mean stuff just because of how they sound. Usagi means rabbit, no matter if it's written "兎", "うさぎ", "Usagi", or "Oosoggy."
