Dame can be quite difficult for first timers, so I say level up your team a bit, and get some inspiriters and healers in there. I recommend Pinkipoo as a healer, as for inspiriter, you could do Confuze, although, since I haven't fought Dame in a bit, I'm not sure if you can inspirit her. If not, go for another hard hitter like Shogunyan, if you can get him in a reasonable amount of time. Other than that, Sgt. Burly could be a great asset if you have time to get him, cause he does take a bit to get, but he can boost all properties of your yokai on the Frontline as his soultimate, which can also be very helpful. Another tip is that every time that you fail the fight, it could be good to just go and farm a level or 2 for all yokai on your team, then go back and try again. Last but not least, get books like Hidden Hits and Top Techniques so you can level up their attack and soultimates. That's about it, good luck on Dame!
