Asides from subbing Kyuukyuu Sentai GoGoV and Kaiketsu Zubat, asides from releasing Ultraman Gaia, Hikari-Senshi also released the very first ninja-themed Sentai team, Ninja Sentai Kakuranger!
The series is about Saizou and Sasuke, descendants of famed ninjas, Sarutobi Sasuke and Kirigakure Saizo who sealed the Youkai Commander Nurarihyon 400 years ago. Because of the trick made by the surviving member of the Youkai clan, Kappa tricks the two in breaking the seal. Now these two, joined by three other descendants of great ninja, become the Kakuranger to fight the Youkai with the aid of the Sanshinshou.
According to sgtkira when he posted this topic on 4chan's /m/ board, asides from GoGoV and Zubat, Kakuranger will be one of their running projects, so expect future Kakuranger episode releases in the future!
