Monster/Male hybrids are rare, but not unheard of. In fact, Males alone are only considered "Uncommon", it's just that its rare for one to retain any kind of Monster traits, most males born between Humans and Monsters are purely Human. Considering his parentage, it's not surprising that Nero would retain Monster powers as well.

Also Luka himself was highly compatible with Monsters and Spirits, able to utilise the four spirits without any side effects at all (in comparison, Lazarus was able to use minor fire spirits, but was killed by trying to use Salamander alone for an extended amount of time). Considering it's his son, it's not unsurprising that he retained compatability with Monster magic.
