Get the toy sword from the kids in the upper left hand corner of sheritan to raise your over all attack power and stock your deck with fire magnas, fates cordials, potions, and all attack magnas you have. You also want to get heavenfall from the chest in the lower right corner and fill all blank magnas with blaze to raise your fire attack's strength. You also want to be at least level 8 with everyone. Now just beat on him untill he does the same thing the first one did that signaled your victory.
Remember that sagi and guillo have the highest attack power so hit with them and heal when nessicery with milly. hope this helps
