Lili is an old friend of Dante's, although they split apart at a very young age. Until recently, they've been hunting on their own separate paths.
Cocky and rude, but quite friendly at times. She can be helpful and she seems to be calm all of the time, never underestimating though. She is fearless, but knows when to back down. She's also very considerate, but won't show it all of the time. She is...very much like Dante to say the least.
Lili carries a pistol that is custom-made by Dante, a well known demon slayer. This pistol's been dubbed with the name, Ice.
Ever since a very young age, Lili has known Dante and been a lifelong friend. This hasn't been apparent though, seeing as how they both split apart in their teen years to pursue their own paths. Dante opened a special shop for demon hunting, while Lili did her own hunting. Only recently have the two crossed paths. They've randomly met up in Gambit's Bar.
