Tokusou Sentai Dekaranger

Tokusou Sentai Dekaranger (特捜戦隊デカレンジャー Tokusō Sentai Dekarenjā), loosely translated into English as Special Investigation Squadron Detective Ranger, is the 28th season of Super Sentai. (Deka is Japanese colloquial slang for "detective" and has no direct translation, but is sometimes written over the kanji for "Keiji" - a more formal term for detective; it is also a Greek prefix "deca", meaning "ten", and a total of ten Dekarangers appear in the series and movie combined). It joined Kamen Rider Blade as part of Super Hero Time.
