Kamen Rider Kuuga vs. the Strong Monster Go-Jiino-Da

In the Super Secret Video (超ひみつビデオ) Kamen Rider Kuuga vs. the Strong Monster Go-Jiino-Da (仮面ライダークウガＶＳ剛力怪人ゴ・ジイノ・ダ), Yusuke reads through newspaper clippings of his actions as Kuuga before he is called upon to fight a new Gurongi called Go-Jiino-Da. The video also previews his Rising Mighty Form.

Summary
Godai awakens from a nap at the Pore Pore Tea Cafe and finds a scrapbook with newspaper clippings about his battles as Kuuga. As he reminisces about each fight, gaining each of his forms and the Goram attachment for the Trychaser, Godai gets a call (presumably from Ichijou, it's never made clear who it is) about a new Gronji monster. Godai heads over and transforms into Kuuga to face off against the beast who introduces himself Go-Jiino-Da (in the Grongi language of course).

After a fierce battle, Kuuga manages to defeat Go-Jiino-Da via Mighty Kick, however, when he stands up, he has suddenly transformed into Rising Mighty Form.
