Makai Tenshi Djibril 4, the beginning of a new saga based at a school seemingly founded by Luvriel for Devil Angels, was released on April 23, 2010, and used, for the first time, graphics displayed in native 576i HD.

In the second game, and its related anime, Hikari Jinno, his sister who was studying overseas, comes to visit, at the same time as Rococo, Asmodeus's sister, decides to attack Rika in revenge for Asmodeus's defeat, turning her into a demonic version of a Devil Angel, causing Hikari to end up a Devil Angel, with Naoto slightly more reluctantly, at first, generating Amore within her, and they manage to purify Rika and defeat Rococo.

Due to NAGI's digital nature, she is able to regenerate from damage and take greater risks, which is needed when the demons deploy the first completely robotic devil...

The sixth, and currently final, game has Luvriel having re-established her school, this time placing the campus within cyberspace, with the assistance of the original devil angels.

"Tenshi no Shiki" (Angelic Ceremony): By performing particular sexual acts under the same conditions as when they accumulate Amore certain powers are stored up.

Despite the names of the forms, they do not visibly cause a Devil Angel to have a greater or lesser chance of turning Dark over time.

"Zero Cannon": An ability shown for Djibril Zero in the anime, it allows her to attack demons at more extreme ranges, by firing a beam of positively charged Amore, with the side effect that it cannot be used to defeat Devil Angels, including artificial ones like Super X-32.

The lyrics, composer, and vocals of the theme songs for all six games were written by the Japanese pop rock band, Funta (Under the name of U), with the help of the anime J-pop company, GWAVE.

Other themes include "Control Is Impossible", A fast tune used in the three games and two anime to indicate a comical or crazy moment, which seems, in a lot of cases, to involve directly Luvriel, becoming almost a leitmotif in itself.
