Are there any bands called 'Lucifer'?

Sensual Phrase (快感 フレーズ, Kaikan Furēzu?) is a shōjo manga series created by Mayu Shinjo. The manga was published by Shogakukan in Shōjo Comic between 1997 and 2000, and collected in 18 bound volumes. It was adapted as a 44-episode anime television series by Studio Hibari and as a series of novels. The series tells the story of Aine Yukimura, a high school student who becomes the lyricist for a Japanese rock band, and her relationship with the band's lead singer, Sakuya Ookochi.

To promote the anime, two real-life bands were formed: Λucifer, the band the story focuses on, and e.MU, a rival band. Both bands continued after the anime ended before disbanding. Within the series, Λucifer’s original name is Lucifer, which is changed to Λucifer (using the Greek letter lambda) when the band decides to go international. For the purposes of the article, the second name, Λucifer is used. Japanese names are given in Western order, with family name last.

Entertainment is a form of activity that holds the attention and interest of an audience, or gives pleasure and delight. It can be an idea or a task, but is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. Although people's attention is held by different things, because individuals have different preferences in entertainment, most forms are recognisable and familiar. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, developed into sophisticated forms and over time became available to all citizens. The process has been accelerated in modern times by an entertainment industry which records and sells entertainment products. Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses a private entertainment from a now enormous array of pre-recorded products; to a banquet adapted for two; to any size or type of party, with appropriate music and dance; to performances intended for thousands; and even for a global audience.

The experience of being entertained has come to be strongly associated with amusement, so that one common understanding of the idea is fun and laughter, although many entertainments have a serious purpose. This may be the case in the various forms of ceremony, celebration, religious festival, or satire for example. Hence, there is the possibility that what appears as entertainment may also be a means of achieving insight or intellectual growth.
