Sourcebook
Intro
In a corner of the city shrouded in the silence of the night, the sound of clashing blades echoes. Unfolding before you is a blood-stained confrontation between brothers: Kagetsu Kurobane, who swings the blade of the Extermination Bureau, and Byakuya Kurobane, the Special Grade Yokai clad in monstrous bones.
Why...? Brother, you're supposed to protect me...!
From the shadows, you secretly watch the battlefield where blades of despair and twisted love collide.
