Requiem

Requiem: also known as Mass for the dead (Latin: Missa pro defunctis) or Mass of the dead (Latin: Missa defunctorum), is a Mass in the Catholic Church offered for the repose of the soul or souls of one or more deceased persons, using a particular form of the Roman Missal. It is frequently, but not necessarily, celebrated in the context of a funeral. Musical settings of the propers of the Requiem Mass are also called Requiems, and the term has subsequently been applied to other musical compositions associated with death and mourning, even when they lack religious or liturgical relevance.

Name: Requiem
Species: demon (demi-succubus)
Occupation: manager of the demon girl band; likes to disguise as a nun in free time

Requiem is a quite old and powerful demon, and used to be a very respected one because of that. However, because of a slip-up she doesn't intend talking about she ended up being the manager of the hellish girl band (it is a quite respectful job, but one she hates; she barely takes care of herself, let alone others! She preferred much more her old job as high-ranking demon)
She's very carefree and does things mostly for her own fun/gain, so here's to hope as a manager she'll learn to be more responsible or else...she'll be fired (in a quite literal way, too).

Thankfully, Requiem is a very charismatic and sly demon, convincing others to do her bidding is her daily bread! Her charisma and experience in her past job make her an excellent leader -when she's up to it, that's it- and since she keeps a mostly friendly demeanor with her girls rather than a bossy one the young demons really like her (even though Rhapsody would prefer a bit more responsibility from her).

Requiem has a incredibly beautiful voice, but lacks any talent in singing; however, she's very good at playing key-instruments like piano, with her favorite being the organ. Maybe that's why she can often be found in churches playing it (she dresses up as a...rather unconventional nun just for fun, she always puts up a masking spell so that humans see her as a regular nun), but it's mostly at night and to her delight, it started the whole "organ playing ghost nun" urban legend.

Partly being a succubus, much of her energy is derived from sex, so she sleeps around a lot (despite what one may think due to also her personality, she doesn't enjoy it much and she's not easily satisfied, she may even curse or kill her partner if she deems them enough of a nuisance). Because of her incubus brother she developed a liking to smoke, she always carries some cigarettes around.

She seems to have known Chante for a quite long time, the two speak to each other in a mokingly-friendly-rivalry fashion.
