How do you like your secondary riders to be introduced?
I just watched Build and Ghost, and recently I started Agito, and they both began with the secondary rider being introduced from the start. While they did do things different (Banjou didn't transform until the first quarter was finished, while G3 appeared before Agito), they were both established at the start of the series, giving them a dynamic with the main hero from the starting line.

Meanwhile, there are series such as Drive and Double, which introduces our secondary hero after the first quarter, meaning their dynamic as characters has to start weeks after we've gotten accustomed to the main hero.

So, I'm curious if you prefer the secondary rider to be introduced once we've had a chance to see our main hero go about it solo, or would you like to seem them together at the starting line, since often times the duo work well bouncing off each other with their contrasting personalities, making things interesting?
Additionally, if you prefer the latter, do you like to see it akin to Kabuto or Build, where our soon to be secondary spends a good amount of time unable to transform, so we still get that chemistry while also seeing the hero work alone, or do you prefer it like Ex-Aid or Ryuki, where the secondary is a rider at the start, for some double rider action from the word go?
