[Leo Novum]

You know, I should be angry at Banjou having a surprising, super secret backstory but I'm not. One of the things that has always made Build stand out from the rest of the Rider shows was how every element was incorporated into the story ranging from Stalk's facial manipulation power, Misora's idol status and Gentoku's presence at the Skywall Incident. The show has not even shied from using the same element twice, like Sawa's traitor status and Utsumi returning from the dead.

Which is why Banjou having nothing special excerpt for a, standard human experimentation and dead girlfriend backstory always rang hollow. As if he was only a Rider because he was a Rider, a tautological entity, if you will. Compared to Sento's very existence, the Isurugi family's past and Kazumi's tragic circumstances, Banjou came across as a bland, hot-headed idiot who just happened to be part of the story.

Some might argue "But Leo Novum! That very fact makes him a hero! He shows that ordinary people can be Kamen Riders. He is the right man in the wrong place! He is Banjou!"

To that I say no thank you. As I mentioned before, Build has a well executed plot which leaves nearly nothing out so it was obvious that Banjou Ryuuga, the man without a past, would eventually become more important to the plot. That is why Banjou Ryuuga being a Martian makes perfect sense.

In fact, I am calling out right now. Banjou's dead girlfriend, Kasumi, is going to be important to the plot again. She either knew who he (Banjou) was or she is going to become one of Banjou's split personalities, turning Banjou into Mahou Shoujo Cross-Z.
