The Secondary Riders are commonly have their own stories. For example, Zeronos has his own story with Ryotaro's older sister, and Ryotaro is nothing to do with his conflict, he has his own conflict. It was same with Blade Series, Kenzaki has his own stories with Hajime, he always helping Hajime (because that, Hajime is more shown up in the series), while Tachibana has his own story, he helping Mutsuki to use his Rider System.

And you think the other media or games are nothing to do? This is the example, Gatack is the Secondary Rider in the series, so he always appear in other media or games alongside with Kabuto. As well as Garren.
