The funny thing is this year Yuma/Tennouji going to become the new Gavan in the Uchuu Keiji Gavan The Movie 2012. Now the three dorm head are Tokusatsu heroes and came from different genres (Kamen Rider, Super Sentai, Metal Heroes) You planning this, aren't you, Toei? XD
The guy that plays Shun's brother...he' played Kyoya...and I was wrong...it's actually 2 tumblers since the host members were also in Tumbling and I believe 3 Kamen Riders and an Ultraman.
