As his life proceeds, we find out his weaknesses and strengths, personalities and ethical codes. As his life proceeds we find him at the age of thirteen.

Seiko was panting heavily as he stood in the middle of a dense forest, facing off against a slouching old man wearing a black cloak with red clouds on it, along with a bandanna covering his face and a large hat. "Don't keep me waiting, Boy," the old man said with a deep, gruff voice. Seiko grinned from under the shadow of his hood and adjusted his goggles, which were on his face covering a large portion of his features.

"You should learn to be a little more patient Sasori-sensei," Seiko responded. Soon a large puppet with strange arms came down at Sasori, and the puppet's right arm had a piston at the elbow and the shoulder while the left arm had almost a hundred slits in it. The right arm was aimed at Sasori. Sasori jumped out of the way, and as soon as the puppet collided with the ground a piston went in and a huge shockwave shook the ground, leaving a crater almost twenty feet wide and six feet deep.

"When will you learn, Seiko? You can't beat me with stupid destructive power," Sasori reminded him.

Seiko sighed and said, "This talk again?" He motioned his puppet to strike Sasori from behind with his left arm, but Sasori jumped into the air. "Not gonna work!" Seiko exclaimed. Medium-sized serrated blades came out of the slits, leaving the arm a completely bladed nightmare, and it flew up towards Sasori, waiting to get in range to cut him into tiny pieces. As soon as the puppet was in place, a long, segmented tail that was sharpened to a point came out of Sasori and slapped the puppet to the ground with incredible force, leaving a dust cloud over the puppet. Sasori landed and chuckled.

"Nice try, Seiko, but you still have a long way to go before you can beat me," he said to him.

We'll see about that,

Seiko thought with a grin on his face. Soon several more serrated blades flew out of the dust cloud and pierced Sasori in several places.

"What!" Sasori said with shock on his face. Sasori's eyes widened even more when he saw that the blades had paper bombs wrapped around them. When they exploded debris and shrapnel flew everywhere, and Seiko was looking with marvel at the victory he had just obtained.

"Awesome! I finally showed you that I could make an effective puppet using explosions!" Seiko said excitedly.

Sasori was in a tree, his face showing a mixture of both anger and joy. He brushed some debris out of his red hair and jumped down. "Good going, Seiko, you nearly ruined my Hiruko puppet. It seems Deidara has been preaching his explosion art nonsense to you again," he observed as he examined the puppet closely. "I guess asking you to hold back on the bombs would be a bit redundant," he added rhetorically.

"Come on, Sasori-sensei, that doesn't sound like something you would want me to do," Seiko said with a confused expression on his face.

Sasori walked over to the old man puppet that was lying in ruin. "The torso and limbs seem okay, but the back is destroyed beyond repair," he observed out loud.

Seiko chuckled and said, "Sorry, Sensei, but you always told me to never hold back when sparring."

Sasori walked away from the puppet and walked over to Seiko. "Go into town and get some new parts for me. Here's some money." Sasori handed Seiko a wad of cash that looked like it could be a small fortune.

"Squandering the Akastuki funds on personal reasons Sensei?" Seiko asked with a sly smile.

"Just get going, and Seiko…"

Seiko had already started off, but he yelled back, "Yeah, yeah, I know, don't keep you waiting."

Seiko wasn't more than a quarter of a mile away when a man came down from a tree wearing a Hidden Waterfall Village uniform, with a headband on his belt. "I shall accompany you, Lord Seiko," the man said to him.

"Does it ever get old, betraying your country?" Seiko asked the ninja.

"If it's for Lord Sasori-"

"Then you would do anything, I know," Seiko finished for him. "It's always the same answer with you Jonin servants."

Eventually they arrived in town, and Seiko walked to a small shop. "Wait here," he told the jonin as he walked in. "Yo, old man, are you here?" he called out.

Sure enough there came an elderly man with a nasty scar running down his face. "Ah, Seiko. Running errands for your Master again?" the man asked.

"Yeah, I broke his Hiruko puppet, and he's pissed so now he has me buying some parts." Seiko handed the old man a list. "I'm sure you have them ready. Oh, and did my custom blades come in today?" Seiko asked, getting excited.

The old man took his time reading the list and said, "Yes they did. All four-thousand of them."

Seiko made a fist pump and paid the old man. "Thanks again for getting those for me," Seiko said respectfully.

"No problem, Seiko, just glad that I can serve you and Lord Sasori," the old man responded with a friendly smile. Seiko nodded and grabbed his supplies.

"See you later!" Seiko called out.

"Everything went well, Lord Seiko?" Seiko's guard asked when he saw him.

"Of course, now hold these for me," Seiko said as he handed him the large amount of blades and puppet limbs. The jonin struggled, but walked in pace with Seiko. "I say we take the short cut through the forest," Seiko suggested.

"I think we should just stick to the path Lord Seiko," the guard said. The truth was he only wanted to not have to travel through uneven land and underbrush while carrying a heavy load.

"No, I feel adventurous today, so we'll be taking the forest route," Seiko insisted.

They walked for almost thirty minutes, having to stop occasionally because the ninja would drop everything after he tripped by a root or rock. "Lord Seiko, can we rest?" he asked panting.

Seiko paused for awhile and said, "Sure. I'm feeling tired anyway." He sat down on a rock and sighed. Jeez…how could I have gotten myself lost, he thought to himself. I don't normally get lost…no…I do, but normally the escort tells me where to go like when we went into the village. So how did we get lost on the way back? Because he was carrying everything and couldn't really see where we were going! Damn. Seiko sighed again and looked around, but couldn't find the nameless jonin. "Hey! Where did you go?" he yelled out in the forest.

He heard no response, until… "I guess the info was right," a man's voice laughed from the forest.

"Yeah, Sasori of the Red Sand took on an apprentice, and here he is," another voice said. Seiko looked high up in a tree to see two men wearing black cloaks with red cloud patterns like the one Sasori wore.

"The Akatsuki!" Seiko spat. The men jumped down to face Seiko.

"We're just grunts, so don't worry about being discovered by everyone else yet. The higher-up wants to have a word with you alone, so we came to escort you too him," one of them said to him with an unfriendly smile.

Seiko looked around some more and said, "And what happened to my escort?"

"Him? Oh, we killed him," the other man said while the first laughed.

"Yeah, he was really easy to assassinate."

Seiko chuckled too, and reached into his belt.

"Stop right there, Kid, we don't have to keep you alive. We specialize in assassinations, so killing you and removing the evidence will be easy. Don't go getting any ideas," the first man warned him.

Seiko pulled out a small scroll and flipped it in the air. "Oh, really? You guys are so tough because you can kill a thirteen-year-old. Well if we're boasting, how about I tell you about the time I killed two B-class ninja from the Akatsuki all by myself, in the middle of the forest?"

The second man got angry and said, "Was that a threat, Kid!"

"Calm down, Nobu, he's just a kid. You know the orders: if he doesn't cooperate, then dispose of him…and he doesn't look like he plans on cooperating," the first man said with a smile while Nobu pulled out a sword. He held the blade towards Seiko, and the metal started to spark with electricity. Seiko's face was mostly hidden by his large goggles and the shadow of his hood, but his grin was obvious to the two men.

"What are you smiling about, Kid!" Nobu asked.

"It's just that I've already won the battle, but you two won't know it until you're dead. I mean, come on, that's pretty funny, right?" After the words escaped his lips, he dropped a smoke bomb on the ground and engulfed them all in a purple cloud.

"When did he get that out!" Nobu asked his partner.

"He must have gotten it when he reached for the scroll!" coughed the other man. Seiko jumped out of the cloud and started to run.

"What idiots," Seiko said to himself. Soon the smoke cleared, and the two ninja chased after Seiko.

"Get back here, runt!" Nobu exclaimed.

"Fire Style: Fire Ball Jutsu!" The partner breathed out a huge fireball, which headed straight for Seiko. Seiko was quick, and he jumped to the side to avoid the huge inferno. Then Nobu slashed down with his lightning sword. Seiko pulled out a kunai to block, but the blade cleaved through the knife and tore tore through Seiko's shirt.

"Missed," Seiko said, and he jumped up to knee Nobu in the face. Nobu was sent flying back into a tree.

"That kid is strong," he said agitatedly.

"Nobu, keep on him!" his partner said urgently. Nobu nodded and jumped back in for another attack. Seiko had a hard time sidestepping the slashes. "Fire Style: Phoenix Flower Jutsu!" said the partner. He fired three large balls of fire at Seiko. Seiko grinned a huge grin from high up in a tree, and he commanded his puppet down below as he saw the fireballs heading towards it. He motioned the puppet to grab a hold of Nobu before he could escape the inferno.

"What!" Nobu said. He tried to break free, but couldn't bust out of the incredible strength of what he thought was the real Seiko. The inferno hit both Seiko and Nobu, and when it cleared Nobu laid on the ground with burn marks all over his body. The puppet had lost its clothes, revealing the puppet joints and almost a thousand slits over its body. "What is that thing?" the partner wondered in shock. The puppet then unsheathed over two thousand serrated blades that made it look like some sort of machine from hell.

"Meet Yamaarashi, boys, my favorite puppet," Seiko whispered to them, even though he knew they couldn't hear him.

"H-help m-me." Nobu said to his partner, but the partner was frozen in place by the bladed puppet, which stood on all fours. "Puppet Master Jutsu: Quills of the Damned!" Seiko said, and on command every single blade fired out of the puppet. Over a hundred blades pierced Nobu, the trees, and rocks.

"Water Style: Water Wall!" the partner exclaimed in fear, and a wall of water erupted in front of him to block all the incoming blades. But the constant showering of blades was too much, and a single blade broke through and pierced the man's leg. When the onslaught of blades subsided, the man dropped and looked around in horror. Every blade had paper bombs attached to them…including the one in his leg. Seiko was high up in the tree with a grin on his face as he heard the two thousand explosions go off simultaneously.

"And then the two ninjas never bothered me again, the end," he said to himself triumphantly.
