"Shisui!"
Fugaku, Akira, and Yagami recognize the broad back of the figure in front of them.
"It's good that you are here! We will leave the rest to you."
They close their eyes and faint from exhaustion.
Shisui turns around and notices a group of Edo Uchiha clan members charging toward him.
"SHISUI!"
A few of them recognize Shisui as their rivals in the clan.
"I will make it quick!"
Shiing…
Shisui activates his Mangekyo Sharingan.
A giant green humanoid being envelops his body. The Susanoo extends its hands and summons multiple shurikens in the shape of Shisui's Mangekyo pattern. Shisui imbues them with green flames and throws them toward the group of Uchiha Edo shinobis.
The group of Edo shinobis also pauses in their assault and makes multiple hand signs.
"Fire Release: Great Fireball Jutsu,"
"Fire Release: Dragon Fire Bullet,"
"Fire Release: Pheonix Flower Jutsu,"
Multiple omni-directional jutsu bombards Shisui's Susanoo. However, the green flame shuriken cleaves through all of them and explodes on top of the Edo group.
Boom…
A giant pillar of green flames engulfs the entire group. Several Magatama beads fly out of Susanoo's chest and seal away the entire group in a barrier.
Hah…
Shisui heaves a sigh of relief and turns his attention toward the rest of the battlefield.
"Fortunately, I made it on time."
After the battle of the first day, he had to return to the village in the order of Minato.
Apparently, several hidden organizations and other underground organizations made their move toward the Hidden villages in the absence of the almost entirety of the Shinobi force.
Minato and the rest of the Kage already predicted such a possibility. So, they made preparations in advance and created a team of powerful shinobis to curb these organizations with evil intentions. And Shisui was the leader of this team.
"So, this is war!"
Kimimaro, who was standing silently beside Shisui the entire time, glances at his surroundings.
Lub… dub…
The pace of his heartbeat increases. His bloodthirsty instincts as a member of the Kaguya clan slowly begin to take over his body. The sclera of his eyes turns red.
Pop… Pop…
Several popping sounds echo within his body. He drags the bones from his body and wields them like a blade.
Shisui notices the battle intent in his eyes and shakes his head.
"Go!"
He gestures to Kimimaro to make a move. During this operation, Kimimaro was also a part of his team.
Despite the latter calm and innocent appearance, he slaughtered the most rebels in this operation.
Shisui turns around and notices the Asuma, Kurenai, and their team struggling against the assault of the members of the Twelve Guardian Shinobis, especially the Flame God of Konoha.
Like others, he also heard the name of Flame God within the notable shinobis of an era in the Uchiha clan record. The Uchiha clan members are renowned for their mastery of the Fire Release techniques, followed by the Sarutobi clan members.
However, the Flame God surpassed both these clans in his mastery of the Fire Release techniques. He was hailed as the greatest Fire Release user of the era.
Whoosh…
Shisui flickers beside the Flame God.
Swish… swish…
He makes a series of hand signs.
"Fire Release: Great Dragon Fire Bomb,"
Shisui spews out a gigantic dragon-head-shaped orb from his mouth. The intense heat from the jutsu raises the heat of the surroundings. Other shinobis quickly vacate the area upon noticing the jutsu.
Asuma, Kurenai, and their teams also retreat upon noticing the flames.
"Leave him to him!" Shisui glances at them with confidence.
"Al-alright!"
Hizashi, who was fighting against Kazuya, also retreats. He nods his head in shock at the sight of Shisui's attack.
"Hizashi-san, please assist Hiashi-sama in battle. We will handle it here." The other Hyuga clan members turn to him.
"Brother!"
Hizashi turns toward his elder brother's battle and notices him being surrounded by several Edo shinobis.
Whoosh…
He quickly flickers towards the group and infuses the chakra into his palm.
"Gentle Fist: Great Vacuum Palm,"
He blows away a group of shinobis and opens a path to unite with his brother.
"Hizashi!"
Hiashi also notices his younger brother.
"What are you doing here?" The latter frowns.
"Brother, I am here to aid you in battle."
"But-"
"The other got reinforcement to help them," Hizashi adds.
"Al-alright!"
Both brothers align their backs against each other and confront the group in front of them.
"This reminds me of the old days of our youth," Hizashi speaks aloud.
"You are right! Even though the Third Shinobi War is a distant memory since we are currently fighting in the Fourth Shinobi war; however, it still feels like yesterday."
HAAH…
Both brothers infuse chakra into their palms and lunge forwards toward their enemies.
"Eight Trigrams: Sixty-Four Palms,"
Both brothers attack their opponents with similar techniques.
"Looks like the future of the Hyuga clan is secure."
The Edo Hyuga elders close their eyes after getting subdued by the combined attacks of Hiashi and Hizashi.
---------
After slaughtering a hoard of White Zetsu, Kimimaro also meets his opponents, a group of four bloodthirsty maniacs with Orochimaru's Earth Curse Seal.
Kuku…
An evil grin appears on Kabuto's face as the four shinobis wreak havoc on the battlefield.
"These four were one of the best test subjects of Orochimaru-sama's cursed seal experiment. Not only did they survive the gruesome experiment of body modification; they even withstood the effects of Curse seal branding and even powered up from it with no side effects.
Well, the only side-effect, if it even could be considered a side-effect is the increase in their bloodthirsty nature. Not only that, after studying the Hashirama cells, I further modified their Curse Seal, further increasing their power three-fold." Kabuto licks his lips.
"Now, show me the true extent of the power I granted to you all."
A melodious sound of flute echoes throughout the battlefield, enchanting every listener on the battlefield. A fair-skinned woman with a slender build taps her fingers on the holes of a flute while blowing it gently. She had brown eyes that accentuate her eyelashes extending into the corners of her eyes as she sports an impassive expression on her face. Her long, untamed, dark pink hair falls past her shoulders with long parted bangs framing either side of her face and one between her eyes.
The breeze of the sea flutters her hair revealing a 'Curse Seal' on the back of her neck. The Curse seal is in a circular pattern of three hooks, similar to a triskelion, a signature of the Earth Curse Seal.
Bang…
Another giant figure sporting a height of 200 cm throws a punch toward an Iwagakure shinobi.
The desperate Iwa shinobi erects an earth barrier around his body, but the solid punch pierces through the earth barrier like a flimsy paper defense and pierces a hole through his gut.
Shoom…
The giant figure absorbs chakra from the body of the Iwa shinobi. The latter's body dries up and snaps like a withered twig. The giant figure tosses away the body of the Iwa shinobi.
The flute woman turns around and glances at the giant figure.
The giant figure has fair skin and narrowed slanted orange eyes. He has a stern look on his face as he glances at the members of the Allied Shinobi forces. He has three tufts of orange hair on his head: a mohawk of sorts that ran down the middle and two similarly styled tufts of hair at the side.
His attire is a beige-colored, sleeveless tunic with a kanji symbol standing for 'the Sound Four' on the hem and a pair of black, three-fourth-length pants that stops just below his knees. He wears black arm-warmers and a necklace comprised of red circular pieces separating long, metallic pieces. He also wears traditional black shinobi sandals with mid-calf leg warmers covered by bandages, and a purple rope-like belt tied in an inverted bow around his waist.
Swish… swish…
Several dark gold projectiles fly out of nowhere and pierce through the bodies of the shinobis. A few of the shinobis attempt to deflect them with their kunais and blade, but the sheer number of attacks overpowers their defenses.
Slick…
A dark-skinned shinobi with black, shaggy hair tied into a ponytail and black eyes steps beside them. He is holding a long bow in his hands. There is a confident grin on his face. He has unique four arms hanging, with each pair hanging in front and on his back.
As for his attire, he wears a black, sleeveless shirt under a sleeveless grey tunic that bore the Kanji symbol of the Sound Four on the hem, and black skin-tight shorts. He also wears black arm warmers, traditional black shinobi sandals with calf-length leg warmers covered by bandages, and a purple, rope-like belt tied in an inverted bow around his waist.
Slick…
He licks his lips and draws his bow again with full tension.
Bleurgh…
He opens his mouth and spits out a sticky gold secretion from his mouth that hardens on exposure to air.
Swoosh…
He releases the tension on the bowstring and fires the arrow. The head of the arrow splits into several projectiles and bombards the area.
"Tayuya, Jirōbō, Kidōmaru, don't lose yourself in too much fun and forget the mission Kabuto-sama gave us."
Another figure steps on the battlefield and warns the three shinobis.
The figure has fair skin and straight, dark blue hair with long bangs that cover each eye. The figure has two separate heads with their bangs parting on opposite sides. Both heads wear a green shade of lipstick, and have dark markings around their eyes, giving them an androgynous appearance. The front head has a smirk on its face while the back head protrudes from the back and hangs limply, making its long hair cover both faces. Both faces have a cursed seal planted on their foreheads just above their eye, which is covered by their bangs.
The twin heads' attire consists of a black shirt under brown tunics with long sleeves and bore the symbol of the Sound Four on the hem, and black skin-tight shorts. They wear black arm warmers, traditional black shinobi sandals with calf-length leg warmers covered by bandages, and a purple, rope-like belt tied in an inverted bow around their waists. The front head wears a dark-red beaded necklace around his neck and carries a giant scroll behind his back through one of the loops of his rope-like belt while the back head has its eyes closed as if in a deep sleep.
Hmph…
The flute woman snorts at him.
"Don't think you can command me, just because you are our leader, Sakon, Ukon!"

A/N:- Unlike Itachi, Shisui, Izumi and others Fugaku, Yagami, and Akira don't have a good control over their Mangekyo abilities which is quite normal for an Uchiha. As for those three, they underwent Izuna's training since their childhood and thus have massive reserves of chakra and endurance to withstand the stress of Mangekyo abilities.
