Shizuo and Izaya have formed a truce of sorts. But what happens when they're given enough time away from one another to think things through? (-Valentine's Day Special-)

All it took was one person to change him. Even if that person wasn't actually human at all.

It's just another day of high school. Fighting between a beast and a flea continue like usual. The school has learned to live with the regular routine. But maybe there's more to it than meets the eye... ((-Valentine's Day Special-))

What did Izaya mean when he said he would be going 'underground? Shizuo knows that he doesn't like the idea of an absent Izaya, since that just has to mean trouble. So, Shizuo goes to find out what the flea is planning...if there's anything at all. But he's in for more than he expected when he makes a sudden decision without a second thought...
