In some anime and manga, the names of characters have nothing to do with the onyomi or kunyomi of the kanji. How can they be read that way? Eg: 虹(なな), 星空(なさ)
1 Answer
Parents can give their children names with any Kanji from the jouyou and jinmeiyou sets, and give them any reading they want even if it's not am established one. 虹 as なな comes from the seven colours of the rainbow.
