Heya!
It's been a while since I last designed a character that I could talk about, gameplay-wise, so let's get to it!
Leila is the heir of the Von Baron family and seeks to rid the world of the dark forces who invaded her kingdom and thus, joins Nayeli & the gang.

Leila is an Armoured unit with high HP and Str, making her a great front liner.
Although her defense is quite low for a tank, she has the Steadfast skill, which has Str% chance to fully negate any physical hit. If she maxes out her strength, this means that she can entirely shrug off 30% of physical attacks sent her way!
To complement her high Str stat, she gets the Greatsword Wield passive, which grants her the ability to wield a subclass of swords, which usually have a higher Might than usual.
Greatswords typically have low accuracy, but she can mitigate this with her Two-Handed Swing Combat Art, which greatly increases accuracy. However this Combat Art only works with Greatswords!
Finally, Leila also has a Door Buster skill, which enables her to open any door without a key, making her a great pseudo-thief when doors need to be opened (however she cannot open chests!)
I hope you look forward to seeing more Leila in Desire's Grove!
