I feel like the mood here rather resembles my previous book "Bright Red Eyes", but truth be told, this was actually intended as the main event and that as something of a bonus manga. The order ended up being switched around because I delayed this one too much. Satori doesn't really run any errands here, so the title is a bit misleading. "Big Sister Goes to Meet a Detective Novelist" would've been more accurate, but I didn't have time to change it even if I'd wanted to, so whatever. I think Satori definitely reads Akyuu's books. These days we know that apparently she leaves the Underground on occasion, but we had no idea back when I started thinking about this, so forgive me. It might also have been very different had it been after the legendary "11 points" incident. The third eye is probably less of a visual organ and more conceptual in nature, but I figured there was a non-zero chance that physically hiding it would work, so that's what I went with. Koishi-chan's good at getting her sister worked up. (unconsciously)
