Miyamoto, an assassin who was known to be the last of his clan. His clan is known to be the one who invented the water dragon kenjutsu, which focus on a swift blade attack. Their stance consist of holding the blade with only one hand, making sure the blade is only below their waist and are able to slashes their weapon with swift and speed attacks. The Daimyo realizes of the potential of the clan so he decided to send troops of Hideyoshi clan to eliminate the Ogawa clan so that the Daimyo can keeps his power. Lucky for Miyamoto, he was able to hide during the attack and survives it while he sees all of his family members slain by the Hideyoshi clan. Now 15 years after the massacre, Miyamoto has turned 27 and sworn to avenge his clan by murdering the Daimyo who gives the order.

Miyamoto adjusts his straw hat, walking around the town of Iyo Province while following the war general of clan Date. He focuses on follows the general toward Aoba castle. The general looks back, Miyamoto quickly shifts his gaze into a Soba Noodle stall, and Miyamoto tips his hat and smile to the vendor as he asked for the price. Acting carefully to not look suspicious. The general turns back and walks into Aoba Castle. Miyamoto nods to the vendor before he takes off and walks toward a shrine near the castle covered with bamboo trees. Miyamoto walks, being careful as he eyes his surrounding before he reaches for a box under the shrine and pulls it out.

He pulls out a silver key from his pouch and unlocks the box, and grabs his family Wakizashi, one with a purple handle and a black cover with white rope ties around the cover and a white shaped star on the handle. He slides his Wakizashi into his belt before he grabs a Silver half face demon Mempo mask. He wears the mask and clips a dark purple cape around his shoulder. Miyamoto tips his straw hat and climbs a tree near the Castle walls, he grabs a hook and rope from his belt and throws it on the roof of the walls. Miyamoto then jumps off the tree and holds on tight on the rope as his feet meets the walls, he begin to pull himself up the walls onto the roof.

Miyamoto make sure no one sees him before he quietly runs on the roof toward the side of the wall that is closer to the castle. He repeats his method of throwing the hooks and climbs onto the second floor of Aoba castle. Miyamoto slides through an airhole between the first and second floor of Aoba castle and crawls in between the planks, making sure his movement is quiet enough, he crouch up toward the opening and looks around, there seems to be 4 Samurai guarding the second floor of Aoba castle. Miyamoto quietly climbs onto the plank flooring and crouch toward a statue to hide behind it. He looks at an entrance that is currently guarded by 1 Samurai, Miyamoto takes a small pebble from the floor and throws it somewhere around behind the guards.Then the guards turns toward the sound, Miyamoto begins to swiftly jumps and holds onto a wooden floor support and climbs on. Miyamoto quietly crouch on the wooden holding and jumps out of an air hole, he then climbs the roof onto the third floor and sneaks through the window. He notices a guard back facing the window, so be quickly pulls out his Kunai from his pouch and stabs it through the guard's throat to instantly kill him before he pulls the dying guard back and throws another onto another guard's throat. Miyamoto eliminated 2 of the general guard and is now facing one of the war general infront of him.

The general stands in shock as he looks at Miyamoto and grabs his Katana from his Koshirae. Before the general could draw his Katana, Miyamoto quickly charges toward the general and knocks the general on his chest with his shoulder. The general grunt feeling the impact on his chest, he pushes Miyamoto away but then feels a sudden pain on his stomach. The general looks down and frowns in horror as his Kimono is damp with blood, the general glares at Miyamoto, who reveals that he has been holding another Kunai on his left hand and stabbed the general while he charged towards him. The general weakly stumbled, he bends to take his Katana from the ground and draws it while glaring at Miyamoto.

Miyamoto takes off his mask and hooks it on his belt while be flashes a smiles at the general, not even bothered to pulls out his Wakizashi as he waits for the general to charge toward him with an open arms. The general groans in pain, he weakly charges toward Miyamoto with a Katana in one hand. "Warrior like you.. are nothing but a mere cowardly rats!" The general screams as he jogs, stumbling toward Miyamoto, The general raises his blade and swing it toward Miyamoto. But Miyamoto then effortlessly skits aside, dodges the blade and slashes his Kunai on the General throat, stabs the Kunai on the general neck before he leans and whisper "You may call it cowardly, but to me it's intelligence." Miyamoto pulls out the Kunai from the general throat and pushes the Kunai through the back of the General before kicking him out of the window. Miyamoto wears his mask back and peers down the window, making sure the Kunai he stabbed on the general is stay intact before he hold on his straw hat and turns to run away from the army.

Miyamoto turns to look at the ladder leads down only to see a samurai climbing on it, he then turn around to runs toward a ladder leading upstairs but sees a samurai has already joins him in the room blocking the path to the ladder. Feeling in distress, Miyamoto hurriedly runs toward a window behind him and jumps out before he throws his hook on one of the roof tile and hangs on to it. Miyamoto quickly pulls himself up and stands on the tile, luckily duck just as an arrow fly and struck on the wall over his head. Miyamoto runs fast as he can around the tile of the castle before he groans and jumps off toward the walls roof and luckily his hand was able to grab the roof tile and able to pull himself up, now standing on the roof of a wall between the woods and the castle. Miyamoto scans his surrounding to look for an opening to hide but unable to find one.

Luckily Miyamoto sees a spot where there is only two archer and one swordsman. Miyamoto uses all his might and runs as fast as a cheetah before he jumps and pulls out his Wakizashi on air before he lands and thrust his blade into one of the archer's shoulder and pulls it out to slit his throat with it. Miyamoto turn around in time to deflect the swordsman attack and slashes his Wakizashi toward the Samurai's head. However, the Samurai was able to block it. The samurai then begin to send rapid slashes toward Miyamoto, Miyamoto's eyes widen as he dodges toward each attack, quickly turns around and duck in time as an arrow was about to hit him. The arrow struck through the Samurai skull. Miyamoto kicks the samurai to throw him off before he swiftly pulls out another kunai from his pouch and throws it straight through the archer's head. Miyamoto smiles to himself under the mask before he quickly take off into the woods, away from every other samurai.

As the road has cleared, Miyamoto hooks his mask back on his belt and takes off his hat and walks in the forest to a shack where he kept his horses. Miyamoto opens a bag on his horse's saddle and takes out his kimono, after he has changes his outfit. Miyamoto casually rides his horse back into the village as if nothing has happened and retrieve his box before he looks at how crowded the castle is. Miyamoto smile to himself and rides away with his horse before the town is instructed to quarantine.

Several days after the assassination, Miyamoto meets his client in the red leaf forest in Kitano Tenmangu, wearing his mask and his working attire. He tosses the article of the assassination toward the client. The client then smiles brightly as he reads it. He then takes out a big purse of coin and toss it to Miyamoto. The client nods happily and bow "It's a pleasure to work with you crow. I hope we can one day drink a sake like a normal samurai." Miyamoto bows back and tips his hat before he turns around and grabs on his horse's red saddle that matches his Yukata top. "I'm no Samurai, Captain. Just a man who makes living off this" with that Miyamoto climbs on his horse and takes off toward a place where the client won't ever know.
