Some background info:The name of the line is transliterated as S.H. Figuarts.The most recent two main Kamen Riders have had combination gimmicks. The two figures pictured are from the show that just started airing, Kamen Rider OOO, and show him in his TaToBa and GataKiriBa combo forms. The half-black, half-white one is the from the show that just ended, Kamen Rider W, and is his Fang Joker combo form.
Though it doesn't actually mean much anymore, the "S.H." technically stands for "Souchaku Henshin," a long line of Tokusatsu figures. The Figuarts ones are significant improvements over the original line, however. It'd be a good thing to catch up on for future news.Thanks for the report!
