At the start of the battle Kazuto quickly activates his Byakugan which he manages to do within a split second due to his mastery over his doujutsu. Suddenly massive trees rise from the ground around Kazuto and within mere seconds he notices water erupting from the surrounding trees and in response Kazuto rotates his body in a counter clockwise direction exerting chakra from all his tenketsu, creating a dome of pure chakra around him which repels the water and also causes multiple trees to be ripped to shreds clearing the area around him upto short range.
Having cleared the threat Kazuto sends his chakra into Hashirama's mind causing him to suddenly lose his ability to see trapping him within a pitch-black void. Using the situation to his advantage Kazuto retrieves a single shuriken from his coat and throws it upward so that it travels towards Hashirama in an arc trough the air, roughly aimed towards the top of Hashirama's head but as soon as the shuriken is roughly above Hashirama Kazuto performs the handseals 'Ram → Rat → Bird → Boar → Tiger' causing the single shuriken to multiple into a thousand which rain down upon Hashirama and his surroundings.

Description:
One of the Three Great Dōjutsu (San Daidōjutsu), the Byakugan is the kekkei genkai of the Hyuga clan. Bearers of this Dõjutsu have almost featureless white eyes. When the Byakugan is activated, the user's pupils become more distinct, and the veins near their temples bulge as the blood flow to their eyes is increased. While having the Byakugan deactivated, Hyuga ninjas have a normal eyesight and no special addition to their vision. While low rank Hyugas will need to perform a sequence of hand seals ( Horse → Tiger with lifting just index fingers → Boar with nearly straightened fingers → Hare → Rat → Dog → Horse → Dog → Hare → Rat → Boar with nearly straightened fingers → Snake with the right index finger lifted straight up) to activate their Byakugan, Hyuga masters will be able to do so without the need for any hand seals and even have it active passively for long periods of time. Once activated, the user gains access to all of the abilities the Byakugan bestows upon them. While, like other Dojutsu, its main ability is to see chakra and the chakra flow in sentient beings, the Byakugan adds a complete new detail and dimension to that ability. The user can not only see chakra and the chakra flow, but also the circulatory system and even the 361 tenketsu. Added to this ability, once activated the Byakugan grants the user a near perfect field of vision 360º around himself (up to long-range if he's a master). This field of vision has only one blind spot, slightly above the 3rd thoracic vertebrae and facing backwards but enables the user to actually even see his own chakra circulatory system and chakra flow, which explains why all Hyuugas are so adept and masterfull of precise chakra control. The last ability the Byakugan has is the ability to zoom in and out, focusing on specific things, piercing beyond matter and energy alike, as well as chakra. This specific ability allows the user to see pass most barriers as well as physical matter (like rock walls, ground, etc) but also energy, being able to focus beyond chakra that might be in front of them or other energies. The zooming ability is enhanced as the user becomes more adept at using his eyes and can even reach distances above 20kms away. Some Hyugas have shown a great awareness regarding agressiveness as well as killing intent, detecting such intentions and emotions from others with more ease than most.
Note: Activation spends a move from the users own move count but once the user reaches Sannin Rank and has gained mastery over Gentle Fist for 1 month, he can activate it passively without spending a move. Because of its low chakra cost to maintain, the user can keep it active throughout the whole fight as long as he has chakra and stamina to do so.
Note: Genjutsu that requires Eye Contact when used against a Byakugan user requires direct eye contact between enemy pupil and user's pupil
Note: Must be activated to use Gentle Fist (Jyuken)
Note: Cannot be blinded by matter, chakra, light or energy
Note: Its tracking abilities are similar to that of a 3 Tomoe Sharingan

Description: The user creates a thousand shadow clones from one shuriken after performing Ram → Rat → Bird → Boar → Tiger, striking down the enemy. This is a technique that combines ninja tools with ninjutsu. Compared to normal shadow clones, clones of material objects are said to be on a far higher level. There is no need for preparations beforehand, like stocking up on shuriken, yet since the shadow clones are real and not illusions, all the shadow blades that fly around are equally lethal.
As Hashirama suddenly dissapears from his sight Kazuto knows that something is off as even if Hashirama were to go invisible Kazuto would easily be able to track him with his Byakugan and that's not the case and what only adds to the oddities is the fact that Kazuto notices bean vines growing around him out of nowhere. Suspicious about the situation Kazuto looks at his own chakra system and realizes that his chakra has been disturbed and then proceeds by releasing a burst of chakra from his entire body, dispersing the illusion.
Regaining his sight of Hashirama Kazuto is suddenly blown upward, but only slightly but quickly finds himself surrounded by dense chakra of which the pressure gradually increases. Kazuto simply molds earth chakra throughout his body, growing an armor of rock from his full body which encases him and takes the force of the wind orb's pressure while Kazuto manipulates the armor growing spikes from his limbs, weakening the orb's density until it disperses.
Finally, Kazuto forms the tiger handseal and expels four dragon shaped fireballs from his mouth, two fireballs travel in an arc towards the right while the other two travel in an arc towards the left until all four of them would eventually converge in on Hashirama simultanously. Along the way the fireballs would simply crash through eventual trees that might be within their paths.

Description: Using their ability to expel chakra from every chakra point on their body, a member of the Hyūga clan can hit their opponent with a blast of chakra that will send them flying away from the user. It was also shown when Kisame's Water Prison Technique trapped Neji that the user can use it to target weak point in the technique that they see with their Byakugan in order to dispel it.

Description: After performing the hand seal Tiger the user compresses a large amount of chakra built up inside their body, before instead expelling it in the form of a number of dragon head-shaped fireballs. The user then skilfully manipulates that great fire, and attacks their opponent. The temperature of the created flames is so great that, even with the briefest of contact, they are capable of easily burning human flesh and the fireballs are dense enough to behave almost as solid, being able to deliver impact damage in adition to the fire damage. However, this also means that they can be deflected as a solid projectiles.
