Half-Devil/Half-Human Divine Dividing (Longinus)

Vali Lucifer is the leader of the Khaos Brigade's Vali Team. He is a descendant of the original Lucifer and the possessor of the Vanishing Dragon, Albion; wielding the Divine Dividing Sacred Gear. As such, he is the direct rival of Issei Hyoudou and Ddraig.

Vali was abandoned by his parents who considered him a monster and was left wandering around. It was during that time that Azazel found the boy and took him into the Underworld, where he raised and trained him.

Vali first appeared in Volume 3 to defeat Kokabiel under Azazel's orders.

He reappears in Volume 4 during the peace treaty between the Three Factions before betraying Azazel and joining the Khaos Brigade. He then fought against Issei. While initially underestimating Issei due to his background, Vali became interested in Issei after Issei manages to overwhelm him despite the fact he was not using his real strength. The battle, however, was ended abruptly by the sudden appearance of Bikou who asked Vali to retreat.

Vali is a powerful fighter who wields the Longinus "Divine Dividing", which holds the spirit of the Vanishing Dragon, the White Dragon Emperor, Albion. Divine Dividing works in the opposite way of Issei's Boosted Gear, in which it halves the opponent's power after coming into contact with them.

Vali can also use the opponent's drained power and add it to himself, which contributed to the defeat of the Fallen Angel Kokabiel during his introductory chapter. He also has a Balance Breaker armor called Divine Dividing Scale Mail, which is similar to Issei's Scale Mail aside from it being white and having Dragon wings. The Divine Dividing also has the ability to halve the size of objects and living beings through the use of its "Half Dimension".

In Volume 12, Vali gains a new form called the Empireo Juggernaut Overdrive, which changes the color of his armor to silver. Like Issei's Cardinal Crimson Promotion, it does not consume his lifespan. In this state, Vali can use an enhanced version of Half Dimension called "Compression Divider", which halves a specific target constantly until they vanish from existence.

Aside from Divine Dividing, Vali has an impressive amount of demonic power, being a descendant of the original Lucifer. This helps him in controlling his Juggernaut Drive as he uses it as an alternative source of power instead of his lifespan; however, if used for extended periods of time, it will eventually cause him to go berserk. Vali has also shown to be extremely talented in using magic, capable of learning Norse Magic in a short period of time.
