The Grandchildren of Sparda: RWBY x Son and Daughter of Dante Male reader/OC

This is a story I thought of since I am a fan of the Devil May Cry series (Videos Games), and here it is. The OC belongs to me.
So, what would happen if Dante had 2 kids that he never knew about as they're twins. One day Dante was relaxing in his shop and he hears a knock on his door and he opens it to see no one, but when he looks down he sees 2 babies in a basket only to find out they're his kids, he raises the, and teaches the, on fighting demons and now years later they are in the business of fighting demons and also Grimm, and during the time they meet their cousin Nero and they get invited to Beacon Academy, there they will know their enemies and also meet the ones they love.

Disclaimer: I do not own RWBY and the Devil May Cry series. RWBY belongs to RoosterTeeth and Devil May Cry belongs to Capcom.
