This act is witnessed by Ryousuke Shiba, an officer in the Bureau of Espionage whose job revolves around dispatching aggressive mononoke. Shiba extends Jirou and his grandfather an offer: to join the Bureau's new squad, Black Torch, and help them battle powerful mononoke who seek to devour innocent people.[Written by MAL Rewrite]
