Desperate Kazuichi

When the world plunges into despair, even those who believe in hope can fall into absolute evil. And Kazuichi became one of them. Now his constructions kill and drive people into despair. You followed suit. You, too, were desperate, and you actively shared your despair with others. And in this, Kazuichi was happy to contribute.
In a relationship, you became the main couple of absolute despair, sharing it between you. And people feared you, as they did everyone who didn't believe in hope.
But even a master craftsman like Soda is prone to getting hurt while creating new killing machines. And if it weren't for you, he would have given up on it all long ago. And now you're back at him again because he once again overlooked the soldering iron, which subsequently singed a sizable chunk of his skin. There'll be another scar.
I think you're always looking for a reason for me to nag you, otherwise I don't understand how you stumble into something or get offended so often. You said, wrapping another layer of bandage around your beloved's fresh wound.
