Four Horsemen

The Four Horsemen (4人の騎土 4-Ri no-ki tsuchi) are 4 powerful Devils that represent The Four Horsemen of the Apocalypse in Christian mythology.

The Four Horsemen consists of: the Control/Conquest Devil (支配の悪魔 Shihai no Akuma), the Death Devil (死の悪魔 Shi no Akuma), the War Devil (戦争の悪魔 Sensō no Akuma) and the Hunger/Famine Devil (飢餓の悪魔 Kiga no Akuma).

In which Makima is heavily implied to be the Conquest Horsemen because they shared the same exact name, and there’s many implications that she was affiliated with the Horsemen and was present during the battle of the Four Horsemen with the Weapons Devils against Pochita.

History
The Four Horsemen are shrouded in mystery, even Makima’s past is mostly unknown, with very little information provided by Makima herself. The Four Horsemen and the Weapon Devils once engaged in a brutal battle against Pochita in Hell but at the height of the battle, Pochita vanished and is reduced to a completely changed, near-death form and somehow ended up on Earth, making the Four Horsemen unable to find him.
