The Ascension Ceremony (帰天 Kiten?) is a magical ritual created by the Order of the Sword. The "ascended" assume angelic appearances and powers, although in reality they merely become demons that can switch from human form to demonic at will.
Although not mentioned directly, it is possible that the ritual was developed by Agnus himself, through research into the true Hell Gate and fragments of the dark angel. The ritual is known to be used on Sanctus, Agnus, and Credo, and also on knights who became Alto Angelos and those slain by Dante in the opera house. In Devil May Cry 4: Deadly Fortune, it is said that those who attempt the ritual, but are too weak, can turn into unnatural false demons and lose their sanity.
The ritual is only partly shown during Sanctus's ascension. Whether Sanctus died from Dante's attack or was merely severely injured is unknown, but he has already healed from the bullet wound by the time Nero reaches Fortuna Castle and is lying on a bed-like altar beneath a canopy. With Credo watching over him dilligently, Sanctus wakes fitfully. Agnus then enters the room and compliments His Holiness, but Credo blocks him from getting too close to the recently ascended Sanctus.
