"It has been a long time, hasn't it Kumoko?" Rosemary said as she stood in front of Kumoko's impromptu grave. "It has been, what? Two months since my last visit? Well, I've been busy. Busy tracking the Demon Lord down. Earlier today, I've got a lead from one of the info brokers I work with. Tomorrow, I'm going to confront her. This could be our last conversation, so I guess this is good bye for now. I'm going to avenge you, that is a promise. It doesn't matter how many bodies I'll have to pile up to achieve that." How much would one event change the course of a story? How would one change cause a butterfly effect that would change how something plays out? Welcome to Dark Mist's Mercenary path. A story of revenge, sorrow, anger, regret, and acceptance. One-Shot for now. I do not own Kumo Desu Ga Nani Ka.
