RWBY: Oretachi Wa Kazoku Desu

Heart, a Tyrannosaurus Faunus who rules over the plains in the wilds of Oban, the newly made continent which was once the island of Menagerie, is given his most important job since he had joined the pride after one hard point in his childhood: To take care of a small human girl who he names Emma.

As the two travel together, Heart starts to learn on what it means to be a father and how important a child is in one's life. However, like any other story of joy and adventure, there is great danger and also....a certain genuine feeling that brings two people together as one.
