Just read that Kakuranger now being have another Episode 1 fansub release. This time it is from Hikari Senshi group. I hope this will continue permanently since Kakuranger is also the sentai that remain rare and hard to get. The group also release Go Go V and, interestingly, Jushi Sentai France Five! See their website : http://hikarisenshi.webs.com/downloads.htm and the List of Super sentai fansubs!
UPDATE: As July 2014, GUIS already complete Kakuranger fan sub. You can check on their website HERE.
