I go through a process were don't really draw but I try too here's lust with his weapon

its a whip with blades on it, you shouldn't be surprised but he uses other weapons such as chains and two sickles also I was thinking about due to some seven deadly sins being related they have a bit of their trait with them so since Wrath and Lust are brothers when Lust is angry he gets violent as Wrath does and Wrath is a bit flirty but due to him not being social he doesn't flirt and when he does its cheesy. 

Also that heart I put is what Vale's heart is what it looks like, he died by a shoot through the heart, rip.
