So I feel these little guys are at their peak form to elaborate on now.
Say hello to Din's latest offspring. Where did they come from? Well, this may be a clue: https://inkbunny.net/s/1653835 So yeah, got ourselves a set of incest twins. Things got a little awkward when they learned their parents were father and daughter, and also kind of confused them on what to call the other siblings. Do they call them aunt and uncle? Or Big sister and big brothers? In the end, it just came down to preference. Every now and then, one of them will refer to Avalon as "Aunt Sister".
As for the kids themselves, let's start off with the little lady. She goes by Sin. I have no idea what Din and Coco were thinking when naming her. But she's your typical 8 year old girl: energetic, outgoing, loves to play outside, a bit of a tomboy, a ton of friends and likes to keep up with the latest rumors around town. She takes great care to protect her brother from bullies, and will show no mercy when defending herself or those she cares about. Unfortunately, thanks to receiving some battle training from her dad, she tends to get in trouble herself because she'll sometimes go overboard.
As for the brother, we have Lae. He is the more reserved and stand-offish of the two. Just as energetic as his sister, but focuses it on more indoor activities. Has a bit of a cynical side to him, and can come off as a self aware smart ass around those he is comfortable with. Being born completely blind, he has been raised somewhat differently than his twin. The town where they live has no special handicapped school, so his parents have taken to homeschooling him. Which has proved beneficial in the long run thanks to his father basically being an immortal being with hundreds of millions of years worth of knowledge and life experience to teach him. The biggest thing being the reading and manipulation of aura energy. Thanks to this, Lae is able to use his aura sensory as a form of sight, though it only works to identify living things around him. For anything else outside his home, his sister is usually there guiding him by the hand around town. He takes comfort in this, knowing it's someone he knows and loves taking care of him.
Overall, we have new mouths to feed in this household. Din's place alone how has, not including himself, 9 people living in it. That's quite family. Eh, dude makes it work. But man, is that grocery bill an eye catcher.
