Work in progress, ne ne. I'm setting it up still.

One of the four Guardians. X was honestly surprised with both him and Leviathan at the beginning, but quickly grew warm to him, glad for a presence from his world, even an unfamiliar one. Harpuia's habit of bowing and being overly formal made him cringe constantly, but it seems that he managed to at least get one of those problems out of the way. As far as X is concerned, time and technicalities don't really matter here -- Harpuia is his son, and he loves him accordingly, even if he deeply wishes that the green male would relax a bit more around him. He's aware of Harpuia's hydrophobia, and generally steps in whenever he can to try and bail his child out of it. He considers both him and Leviathan a little too overprotective.

One of the four Guardians. Just as with Harpuia, he was surprised with Leviathan at first, but also came close to her. She seems generally more relaxed and cheerful than her brother, something X is thankful for. However, with that comes a bit more bratiness as well, something he's certainly not all that thankful for. None the less, she's less formal than Harpuia, and seemed to take to the "family" approach easily -- or so X hopes. As with her brother, he considers her his daughter, and will also gladly say so. He considers both her and Harpuia a little too overprotective.
