So I wanted to discuss who the possible identity of Blood Stalk might be. I know the popular theory is Soichi the cafe owner and it's one that I was thinking especially since I rewatched the opening for Build and notice something I didn't notice before.

So in the scene towards the beginning where Kamen Rider Build is on his bike and he starts to ride and it shows all the main characters I noticed something about the border colors of the characters.


So with the debut of Ryuga turning into Cross Z I noticed rewatching the opening that when his character is shown his border is a darkish blue/purple which is the same color scheme as his rider form.



Then I noticed Gentoku's border which is a dark grey which matches his Night Rogue form.


That's when I noticed Soichi's border which is red which matches Blood Stalk


So I feel like the opening was hinting on who's who throughout the series and it could be hinting that Soichi is indeed Blood Stalk

Also a side note to I'd like to point out I noticed Misora's border was a light blue. I'm not saying she might be a Kamen Rider down the line but that color could hint to something like a full bottle of that color scheme. I also noticed in the opening she's shaking a full bottle next to Sento and Ryuga who are shaking their respectful full bottles that they use to transform into Kamen Riders.


So what do you guys think? I'd like to hear your theories on this.
