Cherub, plural Cherubim, is one of the highest ranking of angels in the Christian angel hierarchy, second only to the Seraphim. Their rank among angels is uncertain but they are always categorized in the First Sphere. Some believe them to be an order or class of angels; others hold them to be a class of heavenly beings higher than angels.
The biblical prophet Ezekiel describes the cherubim as a tetrad of living creatures, each having four faces: of a lion, an ox, an eagle, and a man. They are said to have the stature and hands of a man, the feet of a calf, and four eye covered wings. Two of the wings extended upward, meeting above and sustaining the throne of God; while the other two stretched downward and covered the creatures themselves. Scholars suggested that the Cherub originated from the "shedu"; protective gate-keepers who appear in the form of human-headed winged bulls.
"Origin: Israel. They are the second highest rank of angels. They are the guardians of the Garden of Eden and the gateway to Heaven. It was their role to drive Adam and Eve from the Garden. The plural is Cherubim, which means 'knowledge' and 'mediator.' They look something like a sphinx with four wings, for heads, and four arms."
"The second highest of the heavenly host in Christian lore. The plural form is cherubim. They are said to have four faces and four wings, and are known to act as a chariot of God. They are also mentioned in the Bible as guardians of the garden of Eden, wielding flaming swords."
Cherubs are first encountered in the final dungeon guarding a treasure chest containing the Masakado Boots, and are later seen in the bonus dungeon.
In the 3DS remake, a variant Cherub can be unlocked through Nemechi's male angel form, at a cost of 300 D-Souls. He uses his robotic design from the first Devil Summoner installment. This version's abilities are the opposite of the normal version, being focused on physical attacks rather than magical arts.
