One headcanon that I've had for myself is that Luce is probably one of Reborn's exes, and I'm straight up so fine with that fact if its true. The way Uni calls him uncle does confirm it somewhat to me (im delusional) and it just seems so sweet. They both seem like people who would break up on good terms, and seeing how tight-knit and family-wise Reborn treats Uni will never let me back down from this headcanon
