Muramasa grazes Kagehiro's armor; Kagehiro ignites black blood-flame qi on his blades. 8.0s – 12.0s: Kagehiro slides low, executes a brutal upward cross-cut that shatters Muramasa’s scythe into red glass shards, and follows through with a lethal chest slash. 12.0s – 15.0s: Muramasa crashes into the wet mud dead.
