キバっていこうぜ！！
今度は刑事で、俺、参上。

This poster kinda has a ’踊る大捜査線’/’Odoru Daisousasen’ feel to it…

Truly a first for modern Heisei Kamen Rider series…a second movie for a single Kamen Rider series! And each series is THE lucky one!?
None other than…仮面ライダー電王 (Kamen Rider Den-O)!!

This just further proves how much popularity Ryoutarou, Momotaros-tachi, Yuuto and Deneb have garnered throughout the entire tokusatsu series…so much that Toei can’t bear to let them go! And this time, it isn’t just Den-O and Zeronos…but a third Rider as well…the new blood:
仮面ライダーキバ (Kamen Rider Kiva)!!

The movie trailer:

The plot, as taken from Wikipedia:
Set after the events of 仮面ライダー電王 (Kamen Rider Den-O), the デンライナー (DenLiner) gang have set up a detective agency called the デンライナーポリス, (DenLiner Police) who seek to keep the Imagin that survived the Junction Point in check. However, these Imagin, including ピンクラビットイマジン, (Pink Rabbit Imagin) and クラウンイマジン (Clown Imagin), have been united under the evil ネガタロス (Negataros). Negataros has stolen an extra Den-O Belt allowing him to transform into ネガ電王 (Nega Den-O ()) in order to frame モモタロス (Momotaros) for an incomprehensible crime. In addition, he has teamed up with members of the Fangire Clan to recreate the perfect world of the Imagin. While working with Detective Suzuki to uncover the the whereabouts of the Negataros Corps, 野上 良太郎 (Nogami Ryoutarou), the Tarōs, and コハナ (Kohana) encounter 紅 渡 (Wataru Kurenai) and 野村 静香 (Shizuka), who are looking for the Fangires that Negataros has allied himself with. But they all fall for Negataros’ trap, saved in time by 桜井 侑斗 (Sakurai Yuuto) and デネブ (Deneb), who are also working incognito themselves. Soon after the three Kamen Riders team up to stop Negataros and the Fangire Clan members aiding him.

Some magazine shots featuring the double-Rider-feature:

The Denliner Police have their own agency, logo, and even a poster, which writes
’君も参上！’

Wataru…gets possessed by Momotaros!?!?
Nega Den-O reminds me of Dark Kabuto somehow…

Now this is one movie I will be looking forward to the download available (hopefully).
’cause there is absolutely ZERO chance of Singapore showing this movie on the big screen!!! Damn!!!
