"So what is this place?" Takaharu asked as they walked around a new dojo.
"This is the new Ninjutsu Dojo." Igasaki Tsumuji said.
"Otōsan, who built this?" Yuuka asked him, looking around.
"I did." they heard and then up in the arcs they saw their grandfather.
"Ojiisan? This is amazing I saw the lab you can make all types of poisons in there. It's amazing." Kasumi said, seeing him.
"Grazie! Grazie!" their grandfather said with a slight smile.
"Huh?" Nagi asked.
"It's Italian for 'thank you'," Takaharu said.
"So why are we here?" Yakumo asked.
"You may have some control of your Nintality, but you are all green. You have only the basics mastered. You need to learn more. You need to do more." he said.
"So you will teach us?" Nagi said, looking at him.
"Non-Grazie!" he said with a grumpy face.
"'No thank you!'" Yakumo said to Nagi.
"I don't have the time to teach young whippersnappers. If you want to beat me then you need to learn. My son can teach you. And your first step is mastering this shuriken." he said, and then he threw a smoke bomb. Then appeared before the five of them were five shurikens that they had never seen before.
"What is this?" Yuuka asked, looking at it as she and the others picked it up to examine it.
"Goton Shuriken. If you can master this then you have taken your first step to take me out for the title of the Last Ninja and the Finishing Shuriken," he said then he disappeared in a puff a smoke.
"I hope he won't mind me using that lab. I have been itching to make more poisons." Kasumi said with a smile.
"That lab is for you," Tsumuji said with a smile.
"Huh?" she asked.
"For your training, you must all live here together until the Last Ninja Race is over and one of you has taken the title of the Last Ninja," he said.
"Oh, that makes sense...EH?!" Nagi said, looking at him.
"You need to train together. And truly become a team. But first, you need to start your training. So head out and practice with your new shuriken." he said.
They went to their training ground. And practiced the new jutsus out. "KI NO JUTSU!" the shuriken said after he turned it to the greenwood symbol and inserted it into the Ninja Ichibantou.
"Shuriken Ninpou! Ki no Jutsu!" Nagi said, spinning the shuriken and then pointing his Ninja Ichibantou at a target. But nothing happened.
"Moku Moku Ja!" sounded out of nowhere.
Then Fuuka was attacked by a bunch of leaves and twigs. Sending her flying.
"I am sooo sorry Fuu-chan. I didn't mean to do that." Nagi said to her as she looked like she had found her next target for assassination.
"TSUCHI NO JUTSU!" another shuriken said as Kasumi inserted hers into her Ninja Ichibantou.
"Shuriken Ninpou! Tsuchi no Jutsu!" she said, spinning her shuriken and pointing her Ichibantou at the target.
"Don Don Ja!" the sword sounded.
Then in front of Fuuka and explosion happened in the earth at her feet.
"I'm sorry, Fuuka-chan!" she rushed to her cousin and started brushing off the dirt.
"It's fine," Fuuka said with an evil smile clearly angry. She then twisted the Goton Shuriken into the water symbol and inserted it into her Ichibantou.
"MIZU NO JUTSU!" the Ichibantou said.
"Shuriken Ninpou! Mizu no Jutsu!" she said then spun the shuriken and pointed the Ichibantou at both of them.
"Jabu Jabu Ja!" the sword said and sent a stream of water sending both of them flying with Fuuka smiling.
"Revenge suits you Fuuka." Takaharu smiled as he twisted his own Goton Shuriken.
"KIN NO JUTSU!" the Ichibantou said as he inserted the shuriken.
"Shuriken Ninpou! Kin no Jutsu!" he said, spinning the shuriken.
"Kin Kira Ja!" the sword said as he pointed straight in the air and three metal wash bins appeared and fell one landed on the target the other two landed on Nagi and Kasumi.
"Nice touch, oniichan," she said with a smile as the two of them rubbed their heads from the pain.
"You two are good as always Taka-nii," Yakumo said as he twisted his shuriken to flames.
"KAEN NO JUTSU!" his Ichibantou said.
"Shuriken Ninpou! Kaen no Jutsu!" he said, spinning the shuriken.
"Mera Mera Ja!" it sounded as it shot out a flame to dry off and warm Nagi and Kasumi.
"You pick things up fast as always, Yakumo," Fuuka said with a smile.
"You're one to talk," Kasumi said with a slight smile as she dried off. This caused Fuuka to smile slightly.
The next morning they coming out to eat breakfast. "You three were amazing yesterday," Nagi said to Takaharu and Yakumo seeing them.
"Ninjutsu is easy," Yakumo said with a slight smile as a strange man walked into the room.
"After learning magic," he said, making a fire dragon that sent flames at him. He screamed and ran from the room.
"Thank god," Fuuka said with a smile walking into the room wearing a loose shirt.
"I wanted a pick me up after yesterday's training thanks to those two," she said, taking her seat at the table taking some of her food they had made. "But not only did he come up short in that department. He got clingy this morning." Fuuka said with a smile.
"Ever the femme fetal eh Fuuka-chan?" Kasumi said with a smile.
"A woman has needs Kasumi-chan," Fuuka said with a smile.
"And what do you mean that Ninjutsu is easy?" Takaharu asked, looking at Yakumo.
"Simple Taka-nii," he said, looking at him.
"Learning the snipe magic in England was exciting. And I love getting away with it because no one would admit that they saw some of the more showy spells that I know," he said with a smile.
"But what about being a ninja?" Takaharu asked him.
"I use that to learn more about my target. Nothing more. Nothing less." he said, looking at Takaharu.
"Isn't that disrespecting what ojiisan did? He has taken out dangerous beasts all over the world, communicated with aliens, and created legends all over the world with his accomplishments in the ninja world," he said looking at him.
"You need to grow up Taka-nii," Yakumo said.
At that moment the guns that they use in battle, the Kaikou Ninpou Gama Gama Guns started ribbiting.
"What's this?" Kasumi asked, looking at them.
"The Gama Gama Guns act as detectors for the birth of a new Yokai," Tsumuji said looking at them.
"I guess that's helpful," Fuuka said as she disappeared in a puff of smoke. Then reappeared fully dressed.
"Shall we?" she asked as her, and the others left for the fight with the Yokai.
They rushed to the scene of another Yokai scene. And found Yokai Kappa throwing people into the nearby lake in the city. "I, Kappa-sama, will make you suffer! Be afraid!" as the Hitokarage attacked random people as well. Hidden behind a pillar unseen by the Ninninger was a monster in a cat mask.
"I think that will be enough," he said with a sinister laugh.
They quickly started to fight the Hitokarage defeating them with ease. "Thank you. Thank you." a child said to Yakumo as him and his mother ran away.
Yakumo didn't respond to the boy. He wasn't a hero. All he was doing was fighting the Yokai so that he could become the Last Ninja. And they went to work to fight them.
"Yokai, you are our target for assassination," Takaharu said, looking at the monster.
"The Henge! Nin nin nin, nin ninin nin! Nin nin nin, nin ninin nin!" the Ichibantou said.
"Shuriken Henge!" they said.
"AKA JA! AO JA! KI JA! SHIRO JA! MOMO JA! NINJA!"
"Don't butt in!" Kappa said to them as all but Yakumo rushed into the fight. Fighting both Yokai Kappa and more Hitokarage that had shown up. Quickly the Yokai separated AkaNinger from the rest and they fought for a moment all the while they fought Yakumo watched. He then tossed Takaharu into the lake but he landed on the water like it was a solid object and turned to face the Yokai.
He then jumped and fought the Yokai even more.
"You're not bad for a green kid," he said.
"I'm not green I'm red," Takaharu said with a smug attitude and fought back.
That's when the Yokai blew his breath that was like an icy wind. "You may be red on the outside, but you're green on the inside," Kappa said and that was when the others showed to fight the Yokai having beaten the small fry.
"Now I can save oniichan," Fuuka said as she started to fight the Yokai but then he took advantage of Nagi's and Kasumi's greenness and sent a blast of cold air at the three of them after he used them to trip her up.
"KAEN NO JUTSU!" his Ichibantou said.
"Shuriken Ninpou! Kaen no Jutsu!" he said, spinning the shuriken.
"Mera Mera Ja!" it sounded as it shot out a flame at the Yokai who caught on fire.
"Hot, hot, hot, hot. I can't take this anymore!" the Yokai said, jumping away into the water.
"He got away," Takaharu said looking at where the Yokai had jumped into the water.
"This is easy, Taka-nii," Yakumo said.
"You should pay attention, Taka-nii! Considering you got in a fight against an unknown opponent! Anyway, having the most skilled person defeat the enemy is the most efficient way. I mean you all fell for his attacks after all." he said, disappeared in a puff of smoke.
"How's it going?" Kasumi asked Yakumo.
"Kasumi-nee." Yakumo said looking at her.
"You want to say," he said to her as she walked past him.
"Maybe?" she said.
"I'm the best one to fight this thing," he said.
"Maybe?" she said again.
"We all may be the grandchildren of the Last Ninja...but we each have our own interests beyond ninjas," he said to her.
"That's true. Me and my science/poisons. Nagi and his jokes." she said.
"And I trained hard to become a magician," he said looking into the sky.
"True. Once you figured out the truth," she said, looking at him.
"Truth?" he asked.
"That you can't beat Fuuka-chan and Takaharu-kun as a ninja," she said, looking at him.
"What are you talking about the three of us mastered the Goton Shuriken. If anything they are my equals," he said to her.
"Oh really?" she said to him.
"Your words are as poison-tipped as your weapons, Kasumi-nee," he said to her.
"I'll prove it! No one can beat my Ninpou." and ran off.
"Man...he's still a child in some ways," she said with a smile.
The Kappa arose from a pond and threw some young lovers into the water. "That was refreshing," he said as he and Hitokarage stalked off.
"There you are Yokai," Yakumo said as he jumped onto the scene fully henshined and started to fight the Hitokarage and Kappa. He quickly took out all of the Hitokarage with his shuriken and he went to focus on Kappa. And he succeeded in getting him pinned down but then he kicked him away but he landed on his feet.
"Take this," Kappa said, sending a blast of cold air at AoNinger.
"I know how to take that out," Yakumo said as he pointed his Ichibantou already ready.
"Shuriken Ninpou! Kaen no Jutsu!" he said, spinning the shuriken.
"Mera Mera Ja!" it sounded as it shot out a flame at the Yokai.
"Then how about this?" Kappa said as he raised his other hand and increased the power of the blast and it sent Yakumo flying which undid his henshin.
"Now Assassin-san. It's time for you to get assassinated." Kappa said.
"I don't think so," Takaharu said as he and his sister came in.
"KAEN NO JUTSU!" their Ichibantou said.
"Shuriken Ninpou! Kaen no Jutsu!" they said together spinning their shuriken.
"Mera Mera Ja!" they sounded, as they shot out flames at the Yokai but when it looked like they were going to be overpowered they thrust their Ichibantou into the ground and there were blasts that came out of the ground that was too much for Kappa.
"You may be smart Yakumo. But none of us are unbeatable." Takaharu said to Yakumo.
"If we don't keep training none of what we have been through will matter. Because we will never find what we are heading towards." Fuuka said with a smile.
"So before you talk big beat ojiisan," Fuuka said, turning to the Yokai.
"Or just one of the two of us," Takaharu said doing the same.
Yakumo slightly chuckled as the other Ninninger came to the scene looking at the three of them. "I suppose," he said. And Kasumi smiled at him.
"The Henge! Nin nin nin, nin ninin nin! Nin nin nin, nin ninin nin!" the Ichibantou said.
"Shuriken Henge!" they said.
"AKA JA! AO JA! KI JA! SHIRO JA! MOMO JA! NINJA!"
"Seasoned assassin AkaNinger!" Takaharu said.
"Snipping assassin AoNinger!" Yakumo said.
"Sneaky assassin KiNinger!" Nagi said.
"Sexy assassin ShiroNinger!" Fuuka said.
"Smart assassin MomoNinger!" Kasumi said.
"Shuriken Sentai Ninninger!" they said together.
"We are assassin's and you are marked for assassination yokai," Takaharu said.
"If you think I will go down that easily you are sadly mistaken," Kappa said as he called more Hitokarage for them to fight.
They made quick work of them like they were fighting little children that were having a tantrum. It was made easier with their weapons. Before long it was ShiroNinger and AkaNinger up against the Yokai Kappa.
"Shuriken Ninpou! Kaen no Jutsu!" Takaharu said spinning his shuriken.
"Mera Mera Ja!" the Ichibantou said, sending flames at the Yokai.
"Shuriken Ninpou!Shuriken Ninpou! Ki no Jutsu!" Fuuka said, spinning the Goton Shuriken.
"Moku Moku Ja!" her Ichibantou said as she sent a stream of twigs and leaves that mixed with her oniichan flames making them bigger.
"HOT, HOT, HOT, HOT!" Kappa said on fire.
Then out of nowhere, Yakumo came in.
"Shuriken Ninpou! Mizu no Jutsu!" he said spinning the shuriken and pointed the Ichibantou
"Jabu Jabu Ja!" it said, sending a stream of water at the Yokai.
"COLD, COLD, COLD, COLD!" he said, falling over.
"What are you doing cutting in line?" Takaharu complained.
"I don't see either of your names on it," Yakumo said to him.
"That's where you're wrong," Fuuka said as the Kappa slowly turned around trying to get his bearings. And on his back was a piece of paper taped to its back.
"This Yokai belongs to the sexy and wonderful Igasaki Fuuka. So back off baka." they read aloud looking at the note.
"That's easy to fix," Yakumo said, sending another fire dragon using magic and burnt her note.
"OUCH, OUCH, OUCH, OUCH!" he said as the note burned.
"KIN NO JUTSU!" their Ichibantou said as they inserted the shuriken.
"Shuriken Ninpou! Kin no Jutsu!" they said, spinning the shuriken.
"Kin Kira Ja!" they heard, and three metal wash bins fell onto the Yokai's head.
"They cracked my head plate," Kappa said holding his clearly cracked head plate.
"The Waza! Nanja nanja?! Nanja nanja?!" the Ichibantou said.
The Ichibantou started to glow and the three of them started to slash through Kappa. Then the three of them jumped into the air. "Ninja Issen!" the Ichibantou said.
"Ninja Violent Slash!" they said as they sliced through Kappa making him blow up.
"Who dealt the final blow?" Nagi asked, looking at the three of them.
"Who knows," Takaharu said.
"Fuuka-chan. My eyes are good." Kasumi said.
"More poison eh, Kasumi-nee?" Yakumo asked smugly.
"Don't be like that slowpoke. You can finish it next time...maybe." Fuuka said coy. That's when flames erupted from the spot he blew up. And he grew to giant size.
"Time for the OtomoNin Shuriken that ojiisan gave us," Takaharu said, putting it in the Ichibantou.
"The Shoukan! Dareja?! Dareja?!" the Ichibantou said as they pushed the button.
"Shuriken Ninpou! Shoukan no Jutsu!" they said together.
"Dare ja, dare ja?! Da~re, dare ja?! Dare ja, Dare ja?! Da~re, dare ja?! Shinobimaru! Dragomaru! Dumpmaru! Wanmaru! Byunmaru!" they heard, and they jumped onto their own mecha.
"Shuriken Gatti!" they said.
"Soiya Soiya! Wasshoi Ninja! Soiya Soiya! Wasshoi Ninja! Shurikenjin!" they heard as they became the giant robot.
They swung their sword and tried to slice through Kappa. But he was too fast for them. "Drago Shield," Yakumo said, blocking the icy breath.
"This is too tough..." Kappa said, turning around and extending shoots from his rear end and started flying.
"But he's a kappa," Nagi said looking at him flying away.
"Then we attack from a different point of view," Yakumo said, pulling Takaharu off his chair where he controlled Shurikenjin.
"Shuriken Gatti!" Yakumo said as he spun the OtomoNin Shuriken.
Shinobimaru then got up off the chair he sat in the mecha combination and traded places with Dragomaru.
"Shurikenjin Drago!"
"Yakumo the next time you do that with asking first you will pay," Takaharu said as he inserted his Ichibantou in the spot it belonged now that he wasn't in the chair.
"What are you talking about? You're the one that told me to beat you." Yakumo said calmly.
"That's true oniichan," Fuuka said with a giggle.
They then started to fly after the Yokai. Blasting it here or there until it fell from the sky. They landed and started to slash at it with its tail. "The finish," Yakumo said, pulling his sword from the slot.
"Shurikenjin! DRAGO BURST!" they said as they did the final attack blowing up Yokai Kappa for good.
"I understand why you can't fight Kibaoni," Tsumuji said to his father.
"Yes, I am an old man I don't think I can fight something like him again. I was lucky that it was just Hitokarage last time." Yoshitaka said to his son.
"But why are you making them work as a team otōsan?" Tsumuji asked.
"I've lived for a long time. Perhaps too long," he said and disappeared in a puff of smoke.
"Found it," Nagi said with smile finding the Sealing Shuriken that had made Yokai Kappa.
"I suppose they both are strong," Yakumo said to Kasumi.
"Perhaps there love of being ninja assassins is what makes them strong?" she said with a smile.
"Poisonous as ever," he said and went up to both Fuuka and Takaharu.
"This race is far from over. And I will beat you both to the title of Last Ninja and Finishing Shuriken," he said, looking at the two of them.
"Good. I love a challenge." Takaharu said.
"You have to beat me, first boys," Fuuka said with a smile as she started to strut away.
"Where are you going Fuu-chan?" Nagi asked.
"After a battle like that, a girl has...needs that need to be fulfilled. Don't wait up boys," she said with a smile as she went stalking for her next pray.
