Chapter Guide
Chapter 1: In The Dark of the Night It's raining... no... more like it's pouring. Night has fallen over the ruined city. Many demons are roaming, and it seems like there is nowhere to go at all... but...
A young girl walks the streets alone. The necklace around her neck is a sapphire cross. She witnesses a demon killing a human, and charges in to help.
The demon succeeds at killing the human, but runs off towards the mansion, only to be decapitated by a demon slayer with a katana, who catches the attention of another girl with black hair.
The slayer breaks one of the mansion's windows by kicking a demon head at it, then walked away to report to her boss.
The girl with the black hair had, surprisingly, taken shelter, somewhere in the ruins. From there, she watches as the girl with the blue hair disappears into a, near collapsing, library.
Within the library, the slayer meets with a seventy year old man who is blind, and reports to him about the demons, and gives him new information on them.
Meanwhile, Sapphire kills a demon with her cross, after settling in a restaurant to escape the rain. The demon isn't poisonous, so she consumes it.
Outside, Yusuke saves Zorro from a demon, and they introduce themselves, while they're both on the look out for more demons. When the coast is clear, Yusuke explains that it may not be safe, and leads Zorro to the library she and the blind man stay in.
