Ryu followed Isamu as the man walked down a stairway, leading the young boy into a large, white room. Nothing stood inside of the room, and it gave off vibes identical to the Room of Time and Space to Ryu.
Isamu backflipped numerous times as he flipped onto the back of the room, and Ryu stood on the opposite side of him. Benten, Doki, and Tenjin stood behind a clear wall, where they were safe from any attacks and they could watch the two's fight clearly.
"Don't take me lightly, Hoshiko. I'm stronger than you think." Isamu warned as a small grin planted on his face. Ryu slid into a small stance, and his eyes narrowed.
Ryu vanished, then instantaneously reappeared behind Isamu as he swept his right foot on the ground in an attempt to knock Isamu off his feet. Isamu backflipped as he leapt over Ryu's foot, and threw his right leg down in a bicycle kick. Ryu barely touched Isamu with the back of his right fist as Isamu crashed his foot onto Ryu's head, the young boy's head drooping slightly as his eyes widened. Isamu landed on his feet as he snapped his right leg behind him in a side kick onto Ryu's raised forearms, and, although Ryu blocked the attack, the young boy was still sent flying backwards.
Ryu flipped around as his feet tapped on the wall behind him, and he propelled himself back towards Isamu as his eyes swirled into a scarlet red color and his pupils slit, and his right shoulder down to the back of his right hand was sketched with scales. Ryu span around swiftly as his fingernails snapped into razor-sharp claws, and he blurred past Isamu, a shockwave of wind blasting away from Isamu as four deep slashes cut on his sides. Smoke clouded around Isamu, and in his place with a log with four deep cuts on it's sides. Ryu blinked in confusion.
Isamu threw a punch behind Ryu just as the young boy swerved his head to the left to barely dodge the attack, and Ryu raised his right forearm as another punch crashed onto it. Ryu bent backwards as Isamu's left foot sliced through the air above him, and Ryu blocked a flurry of punches as Isamu lunged his fist forward in a rapid barrage. Ryu grabbed Isamu's left fist with his left hand as he mashed his right elbow on the man's chin, then crashed his left fist on Isamu's cheek. Ryu spun to his left as he hopped, mashing the heel of his left foot onto Isamu's opposite cheek, sending him skidding on the ground, face-first.
"Holy moly." Doki's eyes widened as Isamu wiped a streak of blood from his lips with a grin.
"You were trained well." Isamu flipped the same blade Doki used before out of a tan, small bag on his right thigh.
"By Piccolo-sensei himself." Ryu murmured as he dashed towards Isamu, a shockwave of wind erupting under his feet as he leapt towards the man.
Ryu mashed his right hand's claws onto Isamu's blade to stop it from slicing him, then he leapt to his left to dodge a stab. Isamu spun the blade on his left hand's index finger as he sliced the air horizontally as Ryu leapt backwards, the young boy swerving and dodging swiftly to dodge Isamu's blade. Ryu's left leg snapped upwards as it crashed onto Isamu's wrist, knocking the blade out of his hand. Ryu snapped his left leg onto Isamu's chin and chest in a quick succession, then he rammed his right fist onto Isamu's stomach, sending him skidding on the ground on his back.
Ryu dashed towards his opponent just as Isamu flipped to his feet, lunging a pair of four-pointed stars towards Ryu. Ryu dodged one, then mashed the back of his right hand onto the other, the star clinking against Ryu's imprinted scales. Ryu stabbed his index finger through the hole in the star, then span around as he lunged the blade back towards Isamu. Isamu swerved his head to the right to dodge the blade, then mashed his right fist onto Ryu's cheek as the young boy dashed towards him. Ryu shoved Isamu's fist off his face with sheer strength, and Isamu's eyes widened in disbelief as Ryu crashed his right fist onto Isamu's cheek, sending him skidding backwards.
"I-Isamu's losing!" Tenjin watched in awe.
"And it doesn't even look like Hoshiko's taking him seriously." Doki gaped. Benten watched silently.
Isamu slowly rose to his full height, his eyes wide as he staggered to his right. Isamu exhaled heavily, then grinned, "I guess I should take you a bit more seriously, huh?"
Isamu mashed his hands together, popping his index and middle fingers upwards as thick, blue energy swirled around him. Isamu inhaled as Ryu could see some blue energy swirling into his mouth, and Isamu spewed a large fireball towards Ryu as he cried out, "Katon: Goukakyuu no Jutsu!"
Ryu's eyes widened as Isamu's fireball swirled larger as it neared him, the young boy leaping to his right to dodge the attack. Ryu nearly ran straight into a punch as Isamu lunged his right fist towards the young boy. Isamu's fireball exploded behind Ryu, sparks of flame dying out around Ryu and Isamu as they clashed, Isamu lunging a barrage of punches and kicks towards Ryu as the young boy blocked and dodged each blow thrown at him.
Ryu snapped his right knee onto Isamu's chin once he saw an opening, then he popped his right foot up onto a side kick on Isamu's chin, sending him flying backwards. Isamu backflipped mid-air, then mashed his hands together once more, sticking his index and middle fingers up. Isamu inhaled once more, and Ryu radiated his own gray, thick energy in his right hand, his hand glowing a fiery orange.
"Katon: Housenka no Jutsu!" Isamu spewed numerous smaller, but faster fireballs, and each one slowly locked onto Ryu as they curved towards him.
Ryu's eyes narrowed as he rolled to his left, dodging numerous fireballs as he snapped up to his hands and backflipped away from each attack. Ryu spun on his right hand as he propelled himself towards Isamu, his right hand glowing even brighter as he blurred towards his opponent, then sat his hand on Isamu's chest softly. Ryu's right hand released a dark cloud of smoke, the smoke slowly lighting up as it lit into flames, then sent a fiery shockwave of heat blasting around the room as an explosion of energy erupted around Isamu. Isamu was knocked back onto the wall behind him from the force of the explosion, his eyes wide as he fell face-first on the ground. Ryu exhaled softly as he waved his right hand from the scorching heat that stung on his hand.
"...I believe that Hoshiko has defeated Isamu. Therefore-" Benten began, but Isamu popped his head up immediately, showing that he was still in the fight.
"You're not bad. But I'm not losing to a kid." Isamu grinned as he slowly closed his eyes, his body and face relaxing as a wave of peace washed over him.
An explosion of thick, blue energy erupted around Isamu as the man clenched his hands into fists, his teeth gritting as he hunched over, his muscles straining from the intense pressure being put on Isamu's body.
Something's snapping inside of him. Ryu's eyes twitched briefly. I can't detect his energy signature, but I can tell from the energy radiating outside of him that something's transforming inside of him.
Isamu snapped his eyes open as his eyes widened, his pupils shrinking down as they slowly carved into the shape of a straight line, then snapped another straight line out of it's side as it curved around into a three-pointed star, his eyes shrinking back down to their regular size. Isamu exclaimed as an explosion of energy erupted around him, blue energy swirling around him as he panted heavily, then grinned, "Alright, this is the climax of this battle. Let's go...!"
Isamu vanished, reappearing behind Ryu instantaneously as he threw a quick kick on Ryu's left side, sending him flying to his right. Ryu flipped around as he regained himself, and Isamu reappeared behind the young boy once more, snapping his left leg downwards. Ryu leapt to the right as he dodged Isamu's kick, the power of his attack cracking the floor lightly, and Ryu rammed his left fist onto Isamu's cheek, then crashed his right hand onto his opposite cheek, and finished with a strong punch onto Isamu's face.
Isamu staggered backwards momentarily, then snapped his right foot onto Ryu's waist in a powerful front kick. Ryu was sent skidding on the ground before he flipped back up to his hands, skidding on his hands and feet before he slowed to a stop. Ryu clenched his right hand into a fist softly as he dashed back towards Isamu, blocking a side kick with his right knee, then the young boy lunged a punch with his right fist onto Isamu's raised left forearm, a shockwave from the powerful impact blasting across the room.
Ryu's eyes narrowed as he asked his opponent, "Just how did your speed and power skyrocket like it did?"
"It's my Zatsugan (Miscellaneous Eye). You may not know of it, seeing that you've had no contact to anyone in the Kazu clan for just about your entire life, but don't worry. After this fight, I'll tutor you a bit, if you want." Isamu grinned slightly as sweat dripped down his face. Ryu nodded in agreement.
Isamu lunged his right knee onto Ryu's chest as he hopped up, falling onto his back as Ryu backflipped away from his opponent. Isamu rolled back to his hands, then he did the same hand sign as earlier, except instead of energy, electricity sparked around Isamu. Isamu hunched forwards as he snapped his right fist downwards, clutching onto his right arm with his left hand. The electricity sparking around Isamu swirled down into his right fist as he cried out, lunging his right fist backwards, and dashed towards Ryu. Isamu's speed was so great he was a blur as he dashed onto Ryu's right. Ryu's eyes widened.
I won't be able to block the attack, I've got to dodge!
Ryu swerved his head to the left as he dodged Isamu's left fist, but he fell off balance as Isamu spun to his left, sweeping his left foot onto Ryu's feet and knocking the young boy off balance. Isamu cried out as he spun back around to face Ryu, crashing his right fist onto the young boy's waist as he exclaimed, "Raiton: Kagayaku! (Lightning Release: Sparkling)"
Ryu was sent flying backwards as the electricity swimming around Isamu's hand shot onto his stomach, sending him crashing onto the wall facing Isamu, an explosion of electricity sparking around where Ryu crashed onto the wall. Once the attack died down, Ryu stepped out of the dust from the impact and the attack, his bare stomach shown from a large hole torn in his gi from the attack. Blood leaked out a small cut from Ryu's cheek, and his scarlet red eyes swirled back into their icy blue state, his pupils shrinking back to normal. Isamu breathed heavily as he forced a grin from Ryu's lack of stamina loss, or any sort of sign of fatigue.
"Tough bastard...!" Isamu groaned as he panted. Ryu clenched his hands into fists as golden energy exploded around him, then swirled into a pillar of Super Saiyan ki as his eyes glowed into a turquoise color, his hair spiking up.
The energy around Ryu whisked away suddenly as the young boy closed his eyes peacefully. With a sudden exclaim, Ryu's hair sparked into a golden color, golden ki erupting around him as he cried out briefly, his energy cloaking around him as his eyes pierced onto Isamu's.
Isamu, with a grin, sighed, "Alright, I concede defeat."
Ryu's ki whisked away as his eyes narrowed in confusion, and Isamu explained, "I didn't want a gruesome battle or anything, just wanted to test out your skills. I already went past that, but I wanted to see if I was strong enough to push you to transforming into a Super Saiyan. I can't beat you, Hoshiko... You're stronger than me, and that's just that. But, as I said, you shouldn't underestimate you. Where your power and speed triumph mine, my skill, strategy, amount of techniques, and experience are higher than yours. I could go toe-to-toe with you, if I was sparring for keeps."
Ryu nodded softly, and Benten smiled softly, "That makes Hoshiko the victor of this little match."
Ryu nodded once more, and Isamu grinned, "I'm gonna go get cleaned up, but afterwards, I can tutor you a bit about the skills and techniques needed to become a shinobi. We should have a little bit of time until Akuma decides to hunt for the Bijuus."
Isamu walked out of the little sparring room, and Ryu's eyes slid to the floor as heaved a small sigh. I'll be back home sooner or later. Until then, I'm going to suck as much information out of this situation as I can, and maybe I'll grow even stronger.
