Succubus's Links
He's her annoying, silly goof of a younger brother... and she can't really blame him for horning in on her friend-time with Shiika when he's so smitten. They get along relatively well, though she tends to get exasperated with him.
Feels like he's in the shadow of his big sister all the time, but that might be because he feels practically invisible to Shiika. They get on well enough, and he actually enjoys observing her while she works. Sleeps in her bed when he has to stay home by himself.
