The sun hung low over Konoha's training fields, spilling amber light across the dirt as Iruka stood before his most difficult student. The boy's black hair spiked wildly in every direction, his orange training shirt torn and stained from another "accidental explosion."
Goku grinned sheepishly. "Sorry about the log, Iruka-sensei. I didn't mean to vaporize it."
Iruka pinched the bridge of his nose and sighed. "Goku… you don't have to destroy everything you touch. Power without purpose is just chaos. You can protect people without always fighting."
The boy tilted his head, eyes bright but uncomprehending. "But… if I'm stronger, I win. That's good, right?"Iruka crouched to eye level. "Winning isn't the same as protecting. In our world, shinobi sometimes have to kill. But that's not what defines strength." He tapped Goku's chest, right over his heart. "This is. What you fight for. Who you protect."
For the first time, Goku fell silent. He didn't fully understand — not yet — but the idea settled in his mind like a seed buried in the dirt.
Goku training
Meditation and Control
That evening, Iruka led Goku to Training Ground Three, a wide clearing surrounded by whispering pines. The air smelled of grass and earth. A small stream trickled nearby, its rhythm slow and steady.
Iruka sat cross-legged and gestured for Goku to do the same. "Close your eyes. Feel the flow inside you. You have two rivers — chakra and Ki. One is calm water; the other is fire. You must learn to balance both."
Goku tried. At first, all he felt was heat — that roaring Saiyan energy thrumming in his chest, eager to burst free. But then he felt something else beneath it: a softer pulse, like a breeze swirling inside him.
He opened one eye. "That's… chakra?"
Iruka smiled. "Good. Now breathe. Focus on blending them — don't fight them."
For hours they meditated, until the setting sun turned the stream gold. For the first time, Goku felt stillness instead of hunger for a fight.
The Shadow Clone Lesson
When the sky darkened to violet, Iruka stood. "You've done well. Let's try something harder. Watch closely."
He clasped his hands in a seal, focusing his chakra. "Shadow Clone Jutsu!"
In a puff of smoke, a perfect copy of Iruka appeared beside him. The clone smiled and waved.
Goku's eyes went wide. "Whoa! You made a you!"
Iruka chuckled. "Now it's your turn. Channel chakra evenly through your body, then release it outward — gently. Don't force it."
Goku tried. His first attempt made a small explosion that tossed him backward into the grass. His second fizzled out in a puff of smoke that smelled faintly of burnt leaves. On the third, though — something clicked.
A faint flicker of energy, and a shaky, translucent copy of himself appeared for half a second before vanishing.
Iruka clapped once. "There! That's the start of control, Goku. You'll get stronger through balance, not anger."
Goku nodded, panting, a small smile forming. "Balance… huh."
The Spar
They took positions in the middle of the clearing. Iruka dropped into a low, balanced stance. "Remember — control. No explosions this time."
Goku cracked his neck and grinned. "Got it!"
The spar began. Iruka moved first, fast but measured — a sweeping kick that Goku blocked, countering with a clumsy punch. Iruka deflected it easily and tagged Goku's chest with a palm strike that sent him sliding back.
"Again!" Iruka barked.
Goku formed the hand seal quickly. "Shadow Clone Jutsu!"
A puff of smoke burst beside him — a full, solid clone this time. Both Gokus lunged forward, attacking from opposite angles. Iruka spun on his heel, parrying the first punch, ducking the second. He smiled, impressed.
"Better," he said, "but you're telegraphing your moves!"
He flickered forward, elbowing the clone — it vanished instantly. Goku barely had time to react before Iruka swept his legs out, sending him crashing into the dirt.
Frustration welled up inside him. His tail lashed. "I'm not losing again!"
The air shimmered around his body — that fiery pulse returning. His Ki surged uncontrollably, swirling around his hands. Iruka's eyes widened.
"Goku—stop! Don't—!"
Too late.
A bright orb of crackling golden energy formed in Goku's palms and exploded outward — a raw, instinctive Ki blast.
Iruka threw his hands together. "Water Style: Water Wall Jutsu!"
From the nearby stream, a roaring wave burst upward, forming a curved barrier. The blast collided with it, exploding into steam and droplets that rained over the clearing.
When the mist cleared, Goku lay unconscious on the ground, smoke rising gently from his hands. His chest rose and fell steadily — alive, but drained.
Iruka exhaled, lowering the wall. His face was half-shocked, half-proud. "He learned that by accident…" He knelt beside Goku, lifting his small head carefully.
"You really are something else, kid," he muttered. "We just have to make sure you don't destroy yourself figuring it out."
