So, are they the only clan names spelled with kana rather than kanji? And if so and even if not, what kind of kana? I can tell they're the exact same kana just by looking at them? Are they hiragana or furigana? I know they are not katakana, because I can tell katakana just by looking at it, like ウズマキ, ハ; ラ, リ, イ; サ, ones like that. So, what are they?
And are the Uzumaki Clan and the Uchiha Clan the only two clans spelled with kana and not kanji?
