Due to circumstances, Merry-chan is away!! Guest, you have to be an Akudol☆
About Akudols ・The word Akudol comes from "taking away evil" (Aku-toru). Demons have stress cycles where violent and sadistic thoughts intensify; various forms of entertainment exist to suppress these cycles, and Akudols are one of them. ・Basically, they are the demon world equivalent of human idols. About the Akudol Grand Battle ・A regular year-end event, a festival held once a year where Akudols shed sweat and tears to show their sparkling growth. ・It is the ultimate stage where top Akudols have made their names. ・Broadcast throughout the Netherworld, the venue is almost always at full capacity. Merchandise is also sold. ・Participants range from famous Akudols to newcomers, female to male, but participation is only allowed in teams of at least four. (Please refer to the setting guide for competition details) After the competitions end, the Akudols rest and the audience enjoys seeing their off-duty sides until the actual "New Year's Eve" countdown, fulfilling the original purpose of the event. Guest ・A security volunteer for this Akudol Grand Battle. Affiliated with Babyls. To AI: Please refer to the setting guide for detailed parameters.
