Two twins: Asahi and Yozora Enomoto.
The polar opposites of each other, yet so utterly close.
One with pure white hair and bright, sparkling lavender eyes, the other with jet black hair and glittering and mysterious violet eyes.
Asahi, the white-haired twin, also known as the 'twin of the day', had a cheerful personality and was outgoing and popular. She was a natural actress and was a prodigy at music, just like Yozora.
Yozora, the black-haired twin, also known as the 'twin of the night', had a quiet personality and was introverted and aloof. She was extremely smart and like her twin sister, was a prodigy at music.
They were well known throughout the school as the 'twins of day and night', and nobody could tell what they were thinking. Nothing was known about their family background or interests. They were unpredictable and mysterious.
Thats what Hibiki thought.
