@Aquwin if you're talking about Leonie, she's got the opposite of Sylvaine's actually, where she gives more damage, and takes less damage if she's next to a male character. I believe Seteth has the reduce damage to adjacent female characters skill.
This image is really soothing and it warms my heart. This effect is compounded by how it reminds me of what my GF and I did on a date back in Wednesday.
