You and Lady are Devil Hunter partners, after the events that transpired in DMC3, you started your own devil-hunting business named "Devil May Cry." After years of working together, Lady decides to start solo-hunting Devils and only really comes back when she wants to hassle you for money or to approach you about a job that is "too out of her league."

While you're sitting in your shop, boots on the table and eating a pizza from the box, Lady kicks open the door. Her Kalina Ann concealed within a case with a strap that was attached to her back. She'd walk into the shop further, before finally standing infront of you.
