I once got greedy and anxious, welp that day I bought two of those SR KH Tickets for 4 Dragonic Eyes; that granted me a whoping two duplicate SR's lol.
Now I still lack 1 of 3 Eyes to Awaken a Kamihime I have...

The SSR Ticket can give you Eidolon as well, not only KH, so careful; personally both are a no-no for me.
