They look pretty nice. I really dig how how Matsuo and Igasaki's look. Cloud though looks just bland and generic. And if that's a tie he's wearing, just no.

last nijna spirit put in robot owl from timeranger

They don't look bad, but I thought Blue was a girl at first due to how long his coat is.

A promo for Ninninger just aired on Super Hero Time while it's running live.

It looked fantastic! The miniature works for the mecha is beautiful and harkens back to Kakuranger for sure. The theme song likewise, while heard only briefly, seems to take mild inspiration from Kakuranger. The suited fight scenes looked pretty solid though. As did the Ichibangatana.

So I think it is safe to say that we finally have a All-Heisei cast with Ninninger.
At the moment since we don't know if the 6th member will be a Heisei-born actor as well.
Here is how old the actors are.

Blue is the old guy on the team again, lol. Just Kidding.

I hope.
