I defeated 4 times over and over the challenge fight in kiki boss in nature raid, but the only scene i got so far is green lamia only,and  i had no idea how to unlocked the three supervisor scene. I already defeated all the three supervisor all of them 1 times, then i did some challenge fight in kiki, then i only unlocked green lamia scene how to unlocked kiki, levia,and roseris scene need help?

In the challenge fight, it's randomized who you fight in the last battle, and depending on who you defeted you can get different rewards or scenes.
