DRAGON BALL: Sparking! ZERO

Special Banter scenes are triggered at the start of the battle when you fight certain characters together.
Not entirely sure how many interactions there is but below are a few selections that will give you progression towards the achievement.

(Note 1: You actually need to finish the fight for it to count as quitting back to Battle Setup didn't give any progress)
(Note 2: You can reverse the roles of the characters and it'll also count towards the achievement.)

Edit:
Per GokuBlack's comment, Whis Vs Guldo also work

Edit 2:
If you check Whis's Stamp Book, he has a few challenges labeled as "Special Banter Missons" that will tell you which characters to use. To view the challenge details just click the button to view the details. And by the looks of it there are 32 of these missions which is more than enough to trigger the achievement to unlock.
