Passage: Chinese characters also came to be used to write Japanese words, resulting in the modern kana syllabaries. Around 650 AD, a writing system called man'yōgana (used in the ancient poetry anthology Man'yōshū) evolved that used a number of Chinese characters for their sound, rather than for their meaning. Man'yōgana written in cursive style evolved into hiragana, or onna-de, that is, "ladies' hand," a writing system that was accessible to women (who were denied higher education). Major works of Heian-era literature by women were written in hiragana. Katakana emerged via a parallel path: monastery students simplified man'yōgana to a single constituent element. Thus the two other writing systems, hiragana and katakana, referred to collectively as kana, are descended from kanji. In comparison to kana (仮名, "provisional character") kanji are also called mana (真名, "true name, true character").

Question: What is the name of the writing style in which the hiragana and katakana writing styles are derived from?
kanji
