One day in the Ninja Gungjeon there are two kids who was best friends called Hayabusa and Kagura, They were bestfriends for a long time and since they are ready to face a new start they went to a Assasin's School but Hayabusa and Kagura is seperated to another section. Hayabusa chose the swordmaster's technique and Kagura chose the Maiden's Umbrella Technique. Hayabusa's teacher Chou is teaching him how to master moves and every weekend Hayabusa goes to Chou's House to practice more time. Kagura's Teacher Sohana the Maiden's Queen is teaching her every umbrella technique, it was a bit hard for Kagura to master since she always lose focus because she always thinks about Hayabusa.
After a few months of learning Hayabusa finally mastered the swordmaster's technique and he was greatfully thanking his teacher Chou. Kagura has finally focused on her umbrella and Maiden Sohana manage to give her an umbrella that contains more power and magic, Kagura keeps learning new spells and her favorite spell is the "Shogyo Mujo" but she always fails and still can't control it.
One day the Dark Benendou attacks the village and tries to still the True Assasin's Blade. Hayabusa heard all the screamings, he saw Ninjas entering every villagers house and kill them, Hayabusa was in pure shock he saw many bloods from there blade and Hayabusa was worried about Kagura. Suddenly a ninja entered his windows and tries to execute him. Hayabusa gets his blade as soon as possible and tries to protects himself, the Ninja throws its Petal Barage to try to kill Hayabusa. The ninjutsu always bounces and it was hard for Hayabusa to dodge it until Hayabusa learned a new move creating another shadow form of himself, Hayabusa teleported to the shadow and swings his blade making the Ninja have a wounds. The ninja fell down to the floor touching its wounds and the ninja finally takes of its mask and Hayabusa was shocked that the Ninja is a young woman "Who are you? what are you all doing here in our village? what do you all want?" Hayabusa asked, "We are the Dark Benendou,Just call me Hana, we are here to steal the True Assasin's Blade do you know where it is kid?" as Hanabi answered, suddenly Hanabi throws a smoke bomb and escaped leaving a Wild Flower on the floor. Hayabusa goes quickly to the Ninja Temple where the True Assasin's Blade is put. Hayabusa saw many assasins dead, Hayabusa went upstairs to protect the blade until he encountered the Dark Benendou.
The Dark Benendou laughs at Hayabusa because he was just young and then they tried to kill Hayabusa, Hayabusa was in fear and sit down to the corner staying away from them and he screamed for help, until his teacher Chou came and protected Hayabusa. Chou challenged the Dark Benendou and Hayabusa was determined to be in the fight, The Dark Benendou Ninjas accepted Chou's challenge. The Dark Benendou Ninjas called for more backup and the two was not scared to fight so they attacked them. Chou keeps using his Jeet Kunodo technique and Hayubusa keeps using his new move that he just learned Chou was impressed by him because he never saw anyone that used the move. A few moments the Dark Benendou lost and gave them back the Blade "the man who can beat me has not been born yet" as Chou said Hayabusa chuckled so Chou and Hayabusa manage to go home unti Chou was hit by a Petal Barage bouncing to Hayabusa but Hayabusa countered it with his blade, Chou was hurt and fell down to the floor and said to Hayabusa "to challenge is not the way to hurt somebody but in order" and Chou finally closed his eyes and rest peacefully. Hayabusa cried and tries to find who was the one who killed Chou until Hanabi came out of the Dark swinging her Petal Barrage in her hands. Hayabusa pulls out his sword and quickly attacks Hanabi but Hayabusa missed and Hanabi throws out many Petal Barrage that hanged Hayabusa to the wall, Hayabusa keeps struggling but still cant get out Hanabi gets the blade and sliding it into Hayabusa's neck "how pity of you, i guess you were too much easy as expected, but i think you're cute, well i hpe we meet again Haya" Hanabi said and finally escaped. A few moments the Petal Barrage that hanged Hayabusa fades but Hayabusa was still not happy because from what happened. Kagura finally camed to Hayabusa seeing him in tears and blood all over him and Kagura saw Chou dead and she was deeply shocked. The next day Hayabusa was still paralyzed because from what happened last night Kagura tries to cheer him up but it wasn't that effective. Kagura was sad that time a few moments Hayabusa stand up and went to the hill where Chou and Hayabusa practice every weekend, Hayabusa layed down to the ground and closed his eyes.
