Derikaa or Delicer, is a neologism from the personal pronoun 'delic' in 'psychedelic'. The style originates in the club scene particularly in psychedelic trance music. Urashibu kei can be considered a substyle of Derikaa. It is said to incorporate 1960s fashion into onii kei, basically combining onii kei with hippie/psychedelic fashion. It retains the 'bad boy' image of onii kei while adding 'ethnic' elements like turquoise.
