An ability once exclusive to the Bael clan that has the title of the Great King, being the highest-ranking among all the 72 Pillars, the Gremory siblings Sirzechs Lucifer and Rias Gremory inherited this ability from their mother Venelana Gremory, who was a direct descendant of the Bael Clan. Later on, it is shown that Millicas Gremory has also inherited this ability from his father, Sirzechs.
As its name suggests, the Power of Destruction is a type of demonic energy, that grants its users great explosive power and can completely annihilate things when used. A Devil, with higher demonic energy, will be able to use it more proficiently as in Sirzechs case, where he has mastered his Power of Destruction to the point that it can basically eliminate anything.
Up to this point, the Power of Destruction has taken the form of a radiant red energy that surrounds its user when activated. When used, it seems to be channeled out through the user's hands, which then can be directed towards its target.
|Ruin The Extinct||Sirzechs compresses his Power of Destruction into small spheres that are able to eliminate anything without a trace. He is then able to freely maneuver these spheres and is capable of bypassing enemy defenses to destroy specific targets.|
|Aura of Destruction||Sirzechs' true form where his body transforms into a condensed Power of Destruction in the form of a human-shaped aura. In this form, the Power of Destruction spreads explosively and involuntarily, without it being in his command or control.|
|Extinguished Star||Rias compresses large amounts of Power of Destruction into one giant sphere that is able to eliminate anything in its path, to the extent that it damaged even the enhanced body of Grendel that the Gremory group was facing serious trouble damaging previously. However, Rias, due to her inexperience, requires a considerable amount of time to charge this move. Because of this, she needs her servants to guard and protect her, buying time for her to finish it. Also, while the giant sphere is slow, it also possesses a strong power of attraction capable of pulling enemies present in its effective field, into it.|
