While I caught the Cardinal god theming, I didn't actually realize they were based on the Chinese Zodiac! That's actually rather cool!

Oh, I almost forgot one other point. For episode 38 they used the twin brother of Retsu's actor for the mirror offshoot created by Shiyuu. That's right folks, Takuma from Akibaranger made his Tokusatsu debut in that episode :lol.

I knew about Retsu's mirror clone being his real life twin, but I didn't know he was actually in Akibaranger :lol
