Akiha Tohno

Akiha Tohno is a heroine from Tsukihime who is the younger sister of [Shiki Tohno] and the head of the prestigious Tohno family, as well as a student of the elite Asagami Private Girls Academy.

Background
Born into the prestigious Tohno family, Akiha lived a sheltered childhood under the strict supervision of her father Makihisa Tohno and was seldom allowed to go outside the mansion to play. She was also subconsciously afraid of her brother SHIKI, despite the fact that he never did anything wrong, because she felt that he was different and something was wrong with him. When Shiki Nanaya was adopted into the family, she initially disliked him because he had the same name as her brother. One day while she quietly waited for her tutor to arrive, Shiki took her hand, inviting her to play with him and SHIKI and Hisui, the other children at the mansion. Thanks to Shiki she was able to experience at least some semblance of the joys of childhood. Unfortunately, not soon afterward Shiki was near fatally wounded in an accident and was sent by Makihisa to live with the Arimas, relatives from another branch of the family. Akiha tried to visit Shiki at the Arima house several times early on, but pressure from her father and other relatives, in addition to Shiki's constant visits to the hospital, prevented their meeting. Contact was made all but impossible when Akiha was placed in a boarding school and she was forced to live on the campus. Akiha also states that she sent Shiki many letters, but because he was ordered by Makihisa to never speak to Akiha again, he never replied.

Some time later, Akiha and Hisui learned that Makihisa raped Kohaku daily in order to maintain his demon blood. Akiha decided to free Kohaku from Makihisa and live as a normal maid. Upon the death of Makihisa, Akiha became the head of the Tohno household and, ignoring protests from the remaining relatives, called Shiki back to live at the family mansion with her.
