>>6289615Kamen Rider Ichigou has a pretty good number of Figuarts, some are a little on the old side by now (considering how far they've come in recent years) but as far as I know they're not bad. Not particularly expensive either (especially the Sakurajima variant). There's also this
>>6289556 prototype we saw semi-recently, so there'll be a cool new figure of him out one of these days. May be worth waiting for that if you want to.
As for a cool figure for someone unfamiliar with toku, I think you really can't go wrong with Abyss. He was my first Figuarts at a time I was still unfamiliar with the series (still haven't seen the show he's from, even a couple years later) but he's a sp[spectacular figure. Sculpt, articulation, accessories, paintjob, all excellent. And he goes for stupidly cheap for what a great figure it is. 100% recommended.
