I was wondering about the Darkness Knight as I read the part of Alice trying to save it from dying during a brutal skirmish with an Integrity Knight and the part Kirito mentioned that there are Darkness Knights among the Forces of Darkness about to launch an invasion to the Human World kinda similar to Log Horizon's Raid of the Goblin King arc, the part where the massive army of all evil creatures attacking the land forcing the protagonists and allies to stop them at all costs. What does a Darkness Knight look like as there's no image of it in the LN?
