The family tree grows larger and more complicated. Koda is an incubus. His mom is Sin's Mom. Efret is a War Demon, his Dad is Sin's Dad. Sin's a mix, his mom and Dad aren't together as it was just a fling and he was raised by Efret's Dad and Mom. Koda and Efret are not related in any way. They all just met Koda.
Koda @ Sin: moron brother who doesn't even know how to manifest his wings Koda @ Efret: Another moron, but this one's a box of rocks trying to float on a river stupid
