On the Kumo battlefield,
A riles up his chakra as he engages in a battle against his three instructors.
"Looks like you left me with no choice!"
Clang… Clang…
A removes the locks on his golden vambraces.
Bang… Bang…
The vambraces fall on the ground and create heavy indentations in it. A flexes his hands and swings his arms in a chopping motion. Two black kanji tattoos for 'lightning' are etched on his arms.
A crosses his arms in front of his chest.
Crackle… crackle…
A surge of black lightning surges through his body and creates a storm of black lightning around him.
HAAH…
"MODE: Black Lightning"
Black lightning shrouds A's entire body. His eyes turn red and his fairs stand up due to the powerful lightning jutsu.
Bzzt… Crackle…
A turns his attention towards his three former instructors.
Swoosh…
The next second, he disappears from their vision.
"That chakra mode! A… he…"
The eyes of the three instructors widen in shock.
Bang… Bang… Bang…
A strike down the lightning rods around him and reappears in front of Zenshiro.
BANG…
He uppercuts Zenshiro and sends him flying toward the sky.
Whoosh…
A follows up the attack with another kick and launches him further into the air.
Bang…
A appears above Zenshiro and clutches both his fists together and strikes Zenshiro toward the ground.
BOOM…
A small pillar of dust rises in the air as Zenshiro smashes into the earth.
"A… that chakra mode?!"
The Third Raikage narrows his eyes in shock as A rampage on the battlefield.
"I didn't expect him to master it to such a degree."
"Ay… I never thought you will pass on this secret technique to him." The first Raikage opens his eyes.
"Brother, didn't you also pass down this technique to Ay in hopes of him mastering this technique?" The Second Raikage turns towards his cousin.
Sigh…
The First Raikage sighs and nods his head.
"I did! However, Ay walked down his own path. He surpassed my expectations and became a strong shinobi with his own techniques."
The First Raikage has a proud smile on his face as he glances at his son, the Third Raikage.
"Father, A wasn't headstrong enough to follow my path. So, I passed the secret technique of our clan to him in hopes of him becoming the strongest shinobi of the village and perhaps gain the same level of power as our ancestor." The Third Raikage Ay glances at A battling his three instructors.
The First Raikage nods his head as he recalls the information from his clan texts and scrolls.
Their clan is one of the ancient shinobi clans of the Shinobi world. Back during the era of the Sage of Six Paths, the founder of their clan was one of the disciples under Sage's tutelage. The Sage imparted the knowledge of Ninshu to his disciples and their clan founder was proficient in lightning chakra.
The Sage created the black lightning secret technique and tailored it according to his disciple's needs. Later, the Sage passed down the Six Treasured Tools to his disciples. During the invasion of the demons, the six disciples fought against them alongside the younger son of the Sage.
In that grueling battle, four of the disciples lost their lives, and the fifth disciple went missing. On their death's bed, the four disciples passed their treasured tools to the sixth disciple for safekeeping. Later, the sixth disciple married and found his clan. He passed down the secret technique, and the Five treasured tools to the next generation.
The Giant turtle island Genbu and the temple and the waterfall of the truth are also a part of that legacy.
Years later, those very descendants found the Kumogakure village and protected its people as their leader.
After entering the Semi- berserk state using the Black Lightning Chakra Mode, A easily overpowers the three bodyguards. He binds them with black lightning shackles and seals their chakra.
A turns his attention towards the three former Raikages.
"Well done, A!" The Third Raikage Ay nods his head in approval.
"It's really a surprise to see you master the secret technique of our clan to such an extent." The Second Raikage also nods in praise.
"However, your efforts were in vain. The technique is complete!"
HAAH…
The three Raikage's claps their hand and a pillar of lightning chakra rises from their forehead.
The pillar of lightning shoots towards the black clouds in the form of three consecrating streams. A gigantic concentrated lightning orb the size of a mountain appears in the sky.
The bright glow from the jutsu casts a blinding light on the battlefield. It draws an illusion of a second blue moon in the sky from a distance and illuminates the entirety of the battlefield with its glow.
"What's that in the sky?"
The various exhausted shinobis from other battlefields cast glances in the direction of the gigantic lightning orb.
Gulp…
A and Kakashi gulp their saliva at the sheer amount of chakra present in this jutsu. Lightning Release: Raimu Raito is an extremely powerful cooperation ninjutsu that requires several shinobis to exhaust their chakra for hours.
It's a strategic grade S-Rank ninjutsu that holds enough power to obliterate an entire village. There are no known records of the last usage of this jutsu since none of the victims survived to tell the tale. However, back during the era of the Sage of Six Paths, this technique was created by the founder of the Kumo clan after years of studying Ninshu under the Sage of Six Paths.
Later, he used this technique alongside his subordinates to devastate an entire army of demons. So, the strength of this jutsu is unquestionable.
But in today's battle, even though the scale of this technique is not quite on par with the original creator, it's still deadly enough to raze an entire village. The unlimited supply of chakra from the three Kage class shinobis for hours is enough to generate such a destructive potential.
Izuna recalls the history of the jutsu from his memories. He glances at the situation with slight curiosity in his eyes.
"But Kabuto… what are your intentions with such a target?"
"Dad! That blue moon looks so cool."
Tatsuya stares at the visual of Raimu Raito with a glow in his eyes. The rest of the shinobis in the HQ sweat drops at the little fellow's remark. However, Izuna's next statement leaves them more flabbergasted than anything.
"Do you want to take a closer look at it?"
-------------------------
Back at the Kumo battlefield.
A few minutes ago,
The trio of Kakashi, Guy, and A rush through the battlefield while mowing down hoards and hordes of Zetsu soldiers.
A confronts the three instructors from Kumo while Kakashi protects A from the ambush of any unsuspecting Edo enemies.
Guy continues to dash forward on the battlefield while defeating one Zetsu soldier after another.
Whoosh… Swoosh…
Suddenly, a lean, tan-skin figure with a below-average height appears in front of Guy.
"Leaf Whirlwind,"
Guy performs a series of low and high kicks. The lean figure perfectly replicates all his actions and ends the flurry of kicks with a round-house kick similar to Guy.
He cancels force behind Guy's every kick despite Guy's overwhelming advantage in his Fifth Gate form and aura.
Shoom…
A cyan glow covers the lean figure's body as he blocks Guy's follow-up attack.
Swoosh… Bang…
The lean figure repels Guy's kick with his arm and delivers a frontal kick toward Guy's chest.
Bang…
Guy blocks the kick with crossed arms. However, the powerful force from the kick sends him sliding backward.
"My arms!"
Guy's arms tremble from blocking the powerful force behind the kicks.
"This style…"
He casts another glance at the old man in front of him. The old man has a wrinkled face with grey-dead locks. He sports a Manchu mustache and a trimmed chin beard. He wears a yellow jumpsuit with black stripes and open-toed sandals with a green sweatband, and red square-framed sunglasses.
Guy's memories click in as he recognizes the fragile Edo Old man in front of him.
"Y-you are the legendary Master Chen?!"
Guy bows his head to Chen as a form of respect.
"Looks like people still recognize me even after so many years." Chen locks his hands behind his back and inspects Guy's face.
"Hmm… you seem an awful lot familiar!"
Chen tilts his chin and attempts to recall Guy's identity.
"Ah… I remember now. That technique you used earlier… you must be Dai's son. None else besides me, my late disciple, and Dai know how to perform the Leaf Whirlwind kick. Seems like Dai taught you well." Chen nods his head in approval. He notices the flickering green aura around Guy's body.
"Judging from that aura around your body. It must be the effect of the Eight Inner Gates formation technique."
Chen recognizes Guy's technique with a glance.
"Master Chen, you recognize this technique?" Guy asks in surprise.
"Of course, I do! Your father created this technique to replicate my Eight Inner Chakra Enlightenment."
