Ruby's Scenario: Cameo, at the beggining of the game, she wants to use the fortuneteller skills of Ruby, in order to break her curse, but Ruby can't help and soon Michelle runs away.
Not much is known about Michelle, she does seem to be a traveller and she seems to have stumbled upon the Cursed Gauntlet. She often is depressed cause she feels cursed by bad luck, but this isn't likely just because of the gauntlet, as Kurt has the same gauntlet and isn't suffering any similar problems. In the scenarios she either tries to live with her curse or tries to break it at all cost.
In terms of stats, she is actually the game's second-highest Strength-alligned character (the first being Musol Yanii), though she can be a both competent Magic-user (since she starts out with an Earth Magic Tablet) and Dagger/Bow-user as well, making her the game's most versatile character, if not the most frail.
The only other character beside Kurt to be cursed with a Gauntlet Panel. However, Michelle can never raise her Gauntlet above Level 1, which severely restricts what you can do with her Growth Panel. Additionally, high Strength and Skill make Michelle adept at a range of weapons, but due to her low LP you will want to keep her on the back row (or out of combat completely). The Magic Tablet is off-putting as well. While her Water elemental growth is good, her base Magic growth is poor. Try to learn healing spells like Purify and utilize them out of combat.
