it's in the agreements probably

Whenever I hear Ono and Kamiya in the same anime, I think it was like this

*in the studio meeting*

Finished topic: The main plot
Next topic: Seiyuu

Producer: Any suggestions?

Designer: I would suggest Ono Daisuke and Kamiya Hiroshi.

Producer: Why those two?

Designer: W-well, I would think if they both have a role the anime will get more popular.

Producer: How will that give us more views?

Designer: F-f-fan…girls, crazy f-fangirls

*everyone nods in agreement*
