If you haven't given up yet and haven't found out, the legit tactic I found was to defend or heal until I hit 100 TP while at still over half HP (takes some luck), and used the ultimate 100 TP move. I think that took 3 total uses to end the fight.Can anyone tell me how to defeat the first female boss..i am playing on Android
