Things are going well for Hajime on the freelance photography front. His photographic Halloween observations--a nice cover for a guy just trying to learn about human holidays--have done well. He's pleasantly surprised; he thinks he's doing quite well at creating things for a creature who once knew nothing but mindless destruction. And with the offer of more work? He's got even more of an excuse to get out there and start taking pictures of all the setup for the Day of Lights. If lights are going up, he's taking pictures of them.

Hajime's also trying to take pictures of things that aren't quite so dependent on the holidays. He ends up in some strange places, whether it's out in the hills getting nature shots...or out by the trains. The strangely runed plates have definitely caught his attention.

So now he's out there taking pictures of trains as they go by, making the plates spark. He can study these later...but for now? He's just innocently taking photos of trains for a train hobbyist group. Nothing to worry about, go about your business...
