Actually, there are news reports telling that Gaimu will start in October, meaning Wizard ends later than the other Heisei Kamen Rider shows are. It may last as long as 51 episodes, matching up with Agito.Kurow wrote:It's pretty clear now that Fueki and Wiseman are the same person. Specially after Gremlin guide Nitou to the Wiseman hideout and suddenly the white wizard shows up there. I also agree that he is trying to do something to keep Koyomi alive without magical enery. We have only 5 more episodes left and during that episodes they need to deal with Medusa, Gremlin and Wiseman/White Wizard.
As for the Fueki and Wiseman theory, I believe they're the same person too. Earlier I believe that Wiseman may have been related to Fueki and the former is working against the latter to build the Philosopher's Stone to become human again or create another Sabbath. But after the last arc and this, I'm positive Wiseman/White Wizard is making magicians and causing them to unleash the dark-evolved power of their Phantom to make a PS for Koyomi. That's why he was upset when Haruto gained Infinity; Haruto's sense of hope has purified Dragon and evolved him to a level untouched by his plans.
But this is just my theory.
