I don't think it's wise to tag Rubber Shooter as tanaka_yoshitake at this point. Their relationship was just hinted...

So it's a similar situation to the Masked Hakurei.

Well, now that season 1 ends, it does tell something about the Rubber Shooter, although it ends up with Tadakuni waking up from a dream, there's no other hint that it's not true, aside from different hair color. Also, even if it's a dream, I guess Rubber Shooter is still Yoshitake, because I guess that means Tadakuni maybe know something about Rubber Shooter.
