On the subject of Kurosagi:

[penitence_road]

It occurs to me that I should note that I've read the just-released volume of Kurosagi Corpse Delivery Service, so if, dear Yuletide author, that series is what you're writing for me, have no fears of spoilers or the like. I shall refrain from specifying further, if the new volume is something you would like to but have not yet read, save that it's a fairly major reveal about Sasaki.
