Witch that embodies the evil roaming around the city. She steals people's souls with her beautiful voice. She is actually Olga's disguise.
Here, it's only Alice against her. Normally, that would be a bad thing, but not this time.
Have Alice attack with "Blessed Light". You need to keep close watch of her MP and SP, seeing as Olga uses the MP-draining "Mind Assault" skill. Otherwise, this shouldn't be too long or difficult of a battle.
Olga has learned a new spell while she was away, "Black Fog", which can cause poison, It doesn't cause much damage but its still annoying so have everyone equiped with a Shell Bracelet. Other than that she hasn't learned anything new.
She loves to use medium level spells so be careful! Yuri should transform into Baldo since he will have the element advantage and his "Grace" ability will come in use. Other than her "Black Fog" everything should be fine. Also she knows "MP Assault" and will use it on the person who has the highest MP, so brace yourself.
She hasn't learned anything new from the last time you fought her. But that "Black Fog" of hers can be a hassel, instead of a Shell Bracelet use a Cosmic Bracelet as they add more status to the character.
Just use the strategy you used last time and she'll go down again. Again she uses "Mind Assault" and she will target the person with the highest MP.
