Back at the First Company's camp.
Sakumo glances at the state of his camp and sighs.
There is a gigantic crater in the middle of the camp. Several scorched bodies and grievously injured shinobis are laid inside the giant pit.
"Medics… quick!"
The combat medics quickly escort the injured shinobis to the medical tents for treatment.
Sakumo summons the vice commanders and various captains.
"We have to return to the battlefield!"
He assigns a few teams to guard the camp and leads a group of elite shinobis with him to the battle.
-------------------
Ay and A continue to trade blows with each other and with each strike, the superior strength of Ay pushes A back.
"Your fists have grown weaker with age!" Aye glances at the wrinkles on his son's face.
BANG…
A block one of Ay's punches and counterattacks with an axe kick infused with lightning.
BOOM…
The kick lands straight on Ay's chest. A cloud of dust and smoke rises due to the impact.
Hmm…
Ay walks out of the dust cloud and wipes off the dust from his chest. He cracks his neck and turns towards A.
"Your kicks lack strength; your punches lack resolve. Is this the strength of the current Raikage?"
Shoom…
Ay flickers towards A and lands a heavy blow on him.
Bang…
A block the punch with his arm.
Bleurgh…
A puke out a mouthful of blood. The powerful force from the attack inflicts internal injuries on his body.
Bang…
Ay infuses the chakra in his leg and kicks A away from the battlefield.
Bzzt… Crackle…
Lightning flickers around A's body as he loses the protection of his lightning cloak.
Bang… bang…
Ay continues to abuse him by landing a flurry of kicks and punches in his body. A grimace in pain as Ay breaks almost all of his bones.
On the other side of the battlefield,
The Second Raikage and Minato glance in the direction of Ay and A. The second Raikage shakes his head.
"Ay is too brutal! He is not only brutal to his enemies but to his family, too. However, none of that is nowhere enough to the brutality he underwent to shape his body into an ultimate weapon."
BAM…
A grabs Ay's fist and opens his eyes.
BZZT… CRACKLE…
Black lightning flickers around A's body.
A cloak of black lightning chakra shrouds A's body. Lightning crackles around A's hair and eyebrows. A's eye turns red and the black lightning tattoo on his body spreads across his entire body like totem seals.
"BLACK LIGHTNING CRUSH!"
A clasp his fists into a hammer and smashes it atop Ay's head.
Haha…
A smile appears on Ay's face as he blocks A's fists with his arms.
"This is it!"
BOOM…
Dust and debris fly towards the sky in the shape of a pillar as A land one heavy blow after another.
"Haha… bring it on!" The tattoo around Ay's shoulder activates and he also enters into black lightning chakra mode.
"Hmm… I see!"
Minato understands Ay's intention.
"He is training A in the black lightning chakra mode."
"Correct observation!" The second Raikage nods in agreement.
"The black lightning is the most savage and uncontrolled form of lightning chakra. It is so powerful that it not only hurts the enemy but also the user who is wielding it. With each use, the black lightning will slowly destroy the body from within by slowly rupturing every cell of the body from within. So, the only method to train this technique to the extreme was to infuse killing intent into every black lightning attack and channel it within every bone and muscle."
"Hmm… so that's how it is!" Minato nods in understanding.
"Despite his outer appearance and strength, Ay was very soft inside. He always had a soft spot for his family. When he first performed the ritual of inscribing the black lightning tattoo on A's body, A went into a coma for months. This greatly hurt Ay's feelings and he swore to never train A with such cruelty in his life. So, he handed over the responsibility of teaching A to his bodyguards."
Skirsh… skirsh…
The second Raikage tears his upper garments to reveal his bare chest.
A large black kanji tattoo for 'Storm' is inscribed on his chest.
The second Raikage raises his hands towards the sky and infuses a large amount of chakra into them.
"Storm Release: Thunder God Destruction Sphere," (Ranton: Raijin hakai-kyū)
The dispersed black clouds from earlier attacks gather above the Second Raikage's head.
HAAH…
He makes a series of hand signs and claps his hands together.
CRACKLE… CRACKLE… BZZTT…
The black clouds coalesce together into a giant sphere of supercharged air currents and overloaded lightning bolts with millions of volts of electric current. The compact lightning cloud compresses further and the color of lightning turns black.
The super dense compressed lightning cloud occupies a volume of a water tank.
Bzzt…
Everything in the vicinity of the jutsu gets ionized and even the air turns into a conductor as several bolts of lightning travel through the air and strike the ground.
"You can't counter this jutsu unless you possess a powerful wind release jutsu of the same caliber. So, I would advise you to escape using your teleportation jutsu."
Minato glances at his finger as lightning flickers between them.
'So, this is the true power of the fabled Storm Release?'
Minato can feel the pure force of destruction in the jutsu.
'It is said that the second Hokage was capable of flooding an entire village given there was a water body nearby for him to control. Looks like the same is true for the Second Raikage.'
"I can't escape even if I want to. Since the jutsu will change direction toward my students if I avoid it. So, I can only respond in kind." Minato shakes his head.
He stretches out his arm. Minato infuses a large amount of wind-release chakra into his hand. He shapes the chakra into a Rasengan. The wind-release chakra forms a Fuma shuriken ring around the Rasengan. The jutsu releases grinding sounds similar to the blades of a windmill.
"Incredible!"
The second Raikage witnesses Minato's Chō Ōdama Rasenshuriken with disbelief in his eyes.
"This technique… it… it's the cumulation of peak shape and nature transformation. What genius mind and what amazing talent?" He praises the jutsu from the bottom of his heart.
"I am not the original creator of this technique!" Minato shakes his head.
"Then who is it? Who created such an amazing technique?"
"It's my son!" Minato proudly stares into the second Raikage's eyes.
"I see!" The second Raikage nods and glances towards the clash of two jutsu.
BOOM…
Both jutsu collide with each other. The clash of such powerful jutsu generates a gigantic tornado encompassing lightning and wind blades. The lightning bolt burns down the ground while the wind blades lacerate everything it touches.
"Looks like I got my answer!"
The Second Raikage closes his eyes as the Rasenshuriken destroys the black lightning cloud and engulfs his body. The second Raikage's body vanishes into the motes of light.
On the other side,
Ay, and A's battle also comes to an end as A's fingers finally pierce through Ay's lightning cloak.
"You did it A! You surpassed me." A smile appears on Ay's face as his body slowly disperses.
"Old man, I will never forgive this lesson." A's eyes turn moist and he turns his head away to avoid embarrassment.
Kakashi and Might Guy also figure out the nature of First Raikage's technique.
"His technique is an advanced version of lightning flicker. It's similar to Sensei's flying Thunder God jutsu, where Sensei marks a target and teleports at its location using the spacetime ninjutsu. However, the first Raikage technique is more like an instantaneous movement technique, where he moves between two specific coordinates in his line of sight using his special lightning-based physique."
The tomoes in Kakashi's left eye spin rapidly and turn into Mangekyo Sharingan.
"Kamui!"
