Miraluka

Miraluka is a vampire, Hisui's foster parent and the last "True Ancestor" to walk the earth.

In her origins, Miraluka was among the twelve "True Ancestors" of the vampire race. It is said they were the twelve ladies who followed Jesus, but were not his disciples. On the day of the last supper, all Jesus's disciples were fed bread and wine, as is said in the Gospel, but the twelve ladies who followed him from afar were not fed. After he was crucified and buried, they went to his tomb and drank some of his blood, which had dripped from the wound he received from the holy lance. When they did this, they were cursed to immortality as punishment for defiling God in the flesh and were always threatened by anything holy or natural.

Miraluka would live a number of hundreds of years before finally meeting Hisui. She saved him from having to commit suicide when she killed his parents. Afterwards, she took him in and raised him as her own. This was to be a well achieved feat in her book, because none of the True ancestors ever had children of their own. They all had weak reproductive systems, probably another punishment given to them from the curse they received. They managed to find servants of their own, though. But they would all die eventually, except for Miraluka. Though she never gave birth to a child of her own, she learned how to be a mother through raising Hisui. It would not be a long while before they were separated, however. Miraluka, once with Hisui in the middle of the day, had not applied her sun-block parasol properly, and it had faded. Due to this, she shouldn't have been in the sunlight, but because she was, she turned to dust, and would take a long time to regenerate and heal completely before she met Hisui again.

Before she was taken from him, Miraluka gave Hisui her heart. He almost died once on an overseas trip, and needed a heart in order to survive. She gave it to him so he could live on. The reason she managed to survive herself was because even though her heart was not inside her body, it was only required to exist, even if it was in another person's and it had to keep beating. The connectivity between her and her heart was damaged after the sun-block incident, and she needed another vampire's heart in order to survive. She could've asked Fergus, due to him being pure of the pure, but she needed the heart of a "True Ancestor", which was why she picked Rushella.

Miraluka is the most intriguing of all the characters. She possesses the same unreasonable personality Rushella does, she acts as merciless as Eruru, seductive as Mei, more intelligent than Kirika, elusive than Touko and athletic than Rangetsu.

She is mentioned throught the series, but first appears in the end of Volume 4, and dies officially in Volume 5.
