Hey, look! It's character concept designs for Shura and Alida's son, Lucas! This is a slightly aged-up version of him, though. He's about 15 or so as depicted in these sketches, while his canon age is 11. I love the super-floppy wings and rail-thin body, and I'm really liking the mix of buckteeth and fangs on Animancer's version. I'm also really digging that cute exposed belly caused by the tank top not being quite long enough. XB
