I like the look of Kamen Rider Den-O along with all his various forms, but his series was not among my favorite.
The Imagin (the spirits that possess him and give him his different Kamen Rider forms) are the kind of jokey, comical Japanese entertainment. I didn't like it in my anime growing up, and I don't like it in my live-action Japanese TV and/or movies, either. Just not my thing.
But, if you are a fan of Den-O, and a collector of the SH Figuarts line, then what would Den-O be without his Den Bird cycle?
Ohhh.... but it's yet another damned Tamashii Web exclusive, which means we get to pay double the price for it here in the US. Hooray.
It will be out in Japan in February 2014 for Y4,400 (approx $45.00, but unless it's imported through Bluefin Tamashii, then expect to pay quite a bit more for it outside of Japan.)
