Amu Yunos is found within RC 6, in the following battles:

Mission 4: Scary Story Mission (Boss: Amu Yunos); and

Mission 11: Elusive Mitsudomoe (Bosses: Amu Yunos,  Melord, Kalon).

Keep note that RC 6 battles often cycle around, so it's not unnatural that you won't see certain Raid battles disappearing and appearing. Just check for Raid Battle news within the "Menu" option, assuming it's still there.

I hope this helped! (^^)/
