Hibiki originally owned the Obsidian Glaive, but it was at one point stolen by Ronin.
Shortly after the Ninjas' memories were wiped by Ronin, they traveled to Kryptarium Prison, seeking Hibiki's help. When they arrived, they found the prison under attack by Ronin's samurai. Mistaking the Ninja for more of Ronin's goons, Hibiki fled through the prison until the Ninja fended off the Samurai. Once he was convinced that they were victims of the Obsidian Glaive, Hibiki provided them a map to the Inky Lemonberry in the Toxic Bogs, which they could use to make a Tea of Insight that would enable them to learn the location of the Obsidian Weapons.
