Title: Kamen Rider Kivala: Rider Under The Moonlight (仮面ライダーキバーラ：ライダー・アンダー・ザ・ムーンライト)
Setting time: few years after the event of "Movie War 2010".
Setting world: Due to dimension travels is involves in the story, it is varies.
-Natsumi Hikari, together with Kivala the kivat, were traveling different worlds since Natsumi's grandpa passed away 4 months ago. One day in their travels, they find out that the remnants of Dai-Shocker were rampaging through world after world. (Which later revealed that they are after the Seal Artifacts (封印の神器), which when combined, it has the power to creates and destroys anything) Natsumi, who promised to a girl who she saved, decided to fights against the remnants as Kamen Rider Kivala. She meets new and old allies during the journey, but later she also meets a unexpected rival.
Major points (Spoilers alert!):
・The Seal Artifacts is the mystical artifact that the remnants of Dai-Shocker are after. If you had read the descriptions of each of the 'what if' artworks that featuring Kivala in other forms, you will know what I mean.
・In this 'what if' story, Natsumi Hikari/Kamen Rider Kivala will acquires 6 forms (4 of them has been revealed, but I haven't design the other 2 yet).
・The unexpected character I mentioned on the synosis section is a original character, a human, rival to Natsumi since highschool in the past and is a dark Rider. Most of the time she is on Dai-shocker's side. Note: that character is Tatsuko Yoshida (吉田 起子) a.k.a Kamen Rider Dark Kivala.
・The characters from "Kamen Rider Decade" (Other than Natsumi and Kivala the kivat themself) will not appear in this story, but characters from other Toei tokusatsu series might appears in the middle of the story.
・The last leader of the remnants is somewhat evil, even killing his own comrades to achieves anythings.
