"It all started one winter night.." The Akashi household adopted a 5-year old girl after she had became Akashi Shiori's donor. The girl lived in the orphanage with no earlier memories of her childhood nor her name. Akashi Seijūrō grew to accept his little sister as a family along with his mother, and secretly, his father. He named her Akashi Shina, meaning 'dignity' and 'refinement', also granting her the 'Shi' syllable from his mother, Shiori. Seijūrō cares for Shina like she cares for him. He has her, and she has him. Things started to change when they have 'friends' enter the picture. Akashi Seijūrō found himself in a predicament, he, for once, hesitates to solve. It involves Akashi Shina, his dignified little sister.
