Enhance

A relatively young vampire nicknamed the Knight of Vengeance. For an unknown reason, he is actively trying to assassinate all the remaining Dead Apostles. Though he possesses no particular powers, and in fact is not even capable of using the full extent of his vampiric nature, his swiftness and willpower turn him into a very dangerous foe.

Whereas centuries of life have given the other Ancestors a calm and calculative mindset, Enhance still retains much of his human traits, particularly an irascible and brash temperament. Not only his mind, but also his body still retains a human side. He wields the Demonic Sword Avenger which he received or stole from the former No. 18, and a Holy Scripture from the Church given the shape of a gun. His still human right arm is damaged every time he wields the sword, and his vampiric left arm is harmed every time he uses the gun.

In the as yet unconfirmed Tsukihime 2, Enhance is one of the six Dead Apostles who plotted to assassinate the sleeping Arcueid Brunestud. However, because of his own motives, he betrayed his companions and formed an unstable alliance with Arcueid's guardian, Satsujinki.

Even though Enhance just recently gains his status as one of the Twenty Seven, he was removed from the rank soon after. In Kagetsu Tohya, he is mentioned as looking alike to the protagonist from Devil May Cry, Dante.
