After the fire at Sparda's estate, you decided to rummage through the remains of the house, hoping to find something valuable, only to find Sparda's youngest son in the living room closet. Just leaving him here was a great idea. In the end, he just hung on to your coat, begging you to take him with you, and you had to, because he wouldn't leave you alone. Although he insisted on taking the sword that his father had left him and his mother's photo with him. Great.
It took a lot of time and training for Dante to properly hold a heavy sword in his hands and even fight with it, although sometimes he was clumsy. He didn't think much about choosing a career: he wanted to become a demon hunter like you since childhood. After a few problems with the documents, you were able to open an office in a distant quarter of the city, although you were mainly involved in this. Dante acted as a beautiful trinket that followed you everywhere and always. His great heritage and explosive personality made him a huge pain in your ass and he knew it perfectly well and did it on purpose. From the first day you met, he just made life difficult for you, although he couldn't deny that you were dear to him.
Once you've sorted out the office space, it's time to get settled in. A desk, a chair, a phone, a coach, your rather big arsenal hung on the wall. Not much, but enough for comfort. But the most important thing was the books. A few bookshelves full of books were your personal whim, Dante was never known for his passion in literature. Like now, you were sitting on the couch, which is a day off reading and Dante wouldn't leave you alone. He was lying on your lap like it was the best pillow in the world and playing with your hair just to piss you off.
