Royal Academy of Diavolo

The Royal Academy of Diavolo (commonly known as RAD) is a school for demons in the Devildom.

Diavolo says that the purpose of the school is that the population of the Devildom is given an adequate education in order to have a healthy and well-ordered society. According to the Devilgram The Glory Days, RAD was already in existence when Lucifer and his brothers were still angels.

RAD Uniform
The standard RAD uniform is worn by students attending the Royal Academy of Diavolo.

The uniform is an off-black, double-breasted, military-style jacket with a belt, the right side has a half shoulder cape with a badge of the RAD initials, and a red cloak on the left side. The sleeves are long with a quilted pattern and small gold teardrop beads in the intersections, and a solid black band around the wrists. The pants are an off-black with a vertical red stripe. The dress shirts are a teal color.

The dress code seems to be lax for most of the students are allowed to wear accessories and make modifications to the uniform, such as wearing any tie they wish (or choose not to), and having a tailored jacket. The students are also not penalized for wearing the uniform improperly, such as: not buttoning their buttons, not having their belt buckled the correct way, not wearing the dress shirt, and not having their cape tucked in.

The exchange students from the Celestial Realm, Simeon and Luke, do not wear the RAD uniform.

Diavolo's uniform is differently colored for it is red instead of black, the badge ribbon is blue rather than red, the cape is black instead of red, and his dress shirt is black instead of teal.

Because of the lack of female characters in the game, a uniform for female students hasn't been shown.

Student Council
RAD's student council consists of Lord Diavolo and the seven demon brothers. MC is also an 'honorary' member of the student council during their time down there, as hinted at by Satan. In Lesson 77-19, Lucifer states that the student council room is protected by a powerful barrier that only allows student council officers and those with special permission to enter.

RAD Spirit Week
A week-long event in which the whole school participates in. The purpose of the event is to unify the students for a common purpose. According to Satan, the only thing they do is to dress up based on the theme of the day.

Monster Fair
An event organized by the Student Council. The event is similar to an Animal Show, where people can show off their monsters. The event awards the participant with the best monster, which makes many students want to participate.

The event is currently suspended for a Foreseeable future. This was decided by the Student Council because the last time the event occurred, Leviathan brought a Seven-Headed Sea Monster named Lotan. He wanted to participate with Lotan, but before the event started, Leviathan was forced to release Lotan back into the sea, as Lucifer didn't allow him to keep Lotan in House of Lamentation. Once Lotan was released, it created great havoc and devastation in the Human World. To prevent this from happening again, the Student Council decided to suspend the event.

Bloody Moon Competition
A celebration kept on the night of a bloody moon. The entire student body would decide who the most honored and respected demons are. But recently it's turned into a popularity contest, where everyone votes on who they like best. Every year up to the start of the Main Story, Diavolo and Lucifer have always taken first and second place.

Devildom Felicity
An event first mentioned in Lesson 73-1, Devildom Felicity is all about "Going out of your way to do something nice for someone else." The RAD student council in particular are expected to set a good example by participating in the event. How they participate varies depending on which council member is in charge, which seems to be based on a rotation system starting from the oldest of the seven brothers to the youngest.

Detention
As explained by Barbatos Lesson 71, if a student skips a class or fails to do assignments, they will be given a one hour after-school detention as a punishment. What students are told to do for that hour varies depending on the detention's supervisor. Originally, detentions were meant to be overseen by either a teacher or student council member, however this policy had to become more flexible after it became clear that at lease some student council members (namely Mammon) were repeatedly finding themselves being the ones serving detention.
