Thorne just reminisced when suddenly he was approached by an arrow made from a bandage, and was attacked from below, which he just tanked the hit.
"Hmmm, why did you attack me?" Thorne asked Gunko, standing up after being tipped over by the attack.
"Commander ordered me to teach you armament haki, and I have never failed any orders given to me," Gunko replied, preparing to attack once again, unleashing more and more bandages that cover her body.
"Why not teach me the basics first?" Thorne then asked Gunko, while dodging the attacks Gunko was making.
"Battle is the only teacher that can make you learn, you already know the basics, just try to survive," Gunko replied, followed by an immediate attack against Thorne. Gunko stepped on the bandage she made, with the direction of attacking Thorne, which Thorne dodged and counterattacked with his punch, but Gunko redirected his punch into his face, essentially hitting himself.
"Hmmmm, you are a tricky opponent, huh?" Thorne said, after eating his punch enhanced by the speed of the arrow, Gunko incorporated in the attack, Thorne then transformed into a lightning strike, blitzing towards Gunko, who touched him with armament haki, allowing Gunko to redirect his attack, even with such speed and strength, he can't hit Gunko, but she was able to hit her, with the bandages she have, being transformed into an arrow, piercing him, in his body, as if a Wolly Mammoth, being hunted by primitive humans.
"You must feel every hit I have attacked, see how the flow of will manifest into Armament," Gunko advises, while attacking Thorne immediately, giving him another puncture wound and also attacking Thorne with her knee in his face. Thorne, who was hit, took the damage and counterattacked again, but before Gunko touched his hands, he had already hit Gunko.
"Hmmm, very well," Gunko, who was hit, smiled at Thorne, remembering who his father and brother are, and is said to be more talented than both of them. Gunko then started getting serious, which Thorne felt was a strange haki. He immediately started getting serious, having a premonition of death, lingering over him, utilizing the lightning element and his strength to the fullest, Thorne started attacking first, sending a massive lightning bolt in a shape of a wolf towards Gunko, following with Thorne charging from a different direction, Gunko then redirected the lightning attack towards Thorne, who was attacking from the opposite side of lightning, thorne then grabbed the lightning attack that was hurled by Gunko and return it, at a much faster speed.
Gunko then redirected the lightning once again, but with the full force and speed allowed by the Arrow-Arrow no mi she can generate, riding it with her. Thorne then saw what the next 5 seconds would be, where he was then hit, creating a massive hole in his torso.
Thorne, seeing this, subconsciously tried to dodge, his haki then saw that he was still a little bit too late in and his hand was cut by the attack, then Thorne thought of every possible scenarios and tried to stimulate it in his Observation Haki, all of which resulted in him sacrificing a body part, this all happened in his mind, in 0.000000001 seconds, all of his possible injuries came crashing in his subconscious thought.
Thorne, who saw all of his fate, came back to reality, where Gunko was approaching him, where he can see and process what was happening but his body failed to react, he, who was started getting desperate, unconsciously throw a haymaker to counter the lightning wrapped in bandages with Gunko riding the it, it then hit the lightning, but with a black substance protecting his hand.
"Very good," Gunko complimented, while slamming her knee in Thorne's face, losing his focus, and the attack hit him, but almost all of the force was now offset, leading him to be injured but not as severely on his vision, Thorne then stood up, remembering the entire process he subconsciously used the armament haki, he then tried it, again but failed, while this is happening, Gunko, then, repeated her attack, going towards Thorne, who just fired his lightning towards the bandages, then attacking Gunko directly, in which Gunko replied with a punch projecting her Armament outwards, which instantly overpowered Thorne and dislocated his shoulder.
"Ughh, this is frustrating me," Thorne said, looking at the arm that was bend in direction in does not supposed to go, Gunko, then hurled a bandage arrow like a spear, towards Thorne, imbued with more armament, in which Thorne unsheated his sword using his left hand to get use the Leviathan sword, sending a flying slash powered powered by a lightning, it resembling a large snake towards Gunko's spear, which Gunko, summoned more bandaged to repel back towards Thorne, who just waited for the attack, and started focusing, more and more until he reached a deeper dive, it was here that all of earlier scene was being replayed in his mind, at such speed that it played more than a hundred times before a blink of an eye.
Thorne suddenly opened his eyes, watching Gunko repel the attack with speed enhanced by her fruit. He breathed in, recalling the scene once more, before exhaling. With Armament Haki covering his unsheathed sword, Thorne jumped towards Gunko, meeting her attack with his own. They stood still for a second before Thorne overpowered Gunko, who had learned hardening and emission at the same time. They sparred a few more times to ensure that Thorne was able to output his haki without having to face deadly attacks before it worked. After 100 rounds of sparring, Gunko was assured that Thorne was able to freely use his armament.
"Good, that's it, we would now proceed towards the next part of your training, wear these Seastone shackles, you may remember it from Sommers, but it has a different function, it would drain your Armament haki much faster," Gunko suddenly said, taking out a cuffs to put into Thorne.
"Why do I need to wear this?" Thorne asked, while putting in the restraint cuffs, looking at Gunko.
"To ensure that you would be able to use Armament Haki as precisely as possible, since Armament is limited, making sure that you would not release more than needed.
Thorne then tried using his armament, but suddenly felt that he was using twice his intended use, draining his reserves twice as fast as before. Gunko then attacked him, using her emission with the arrow bandaged again. Thorne then counterattacked with his own, swinging his sword and imbuing his Armament haki, using emission, their attacks have having strength that can shatter entire buildings if they hit.
Both Gunko and Thorne fight against each other again, slashes met with arrows, both using their armament haki to their fullest, until in one clash, Gunko and Thorne were using their signature moves, Thorne then summoned every lightning he could to TANNGRISNIR AND TANNGNGOSTR.
With them having a different color, being covered with armament haki, with Gunko making a spinning drill arrow, with a direction arrow to spin it into a clockwise position, when they both approached each other, they had a moment of standstill, where they clash was not moving until Thorne, suddenly runs out of Armament haki, which gives Gunko an advantage, hitting Thorne with the full force of his attack, with the lightning still hitting Gunko.
Thorne, who was hit by Gunko, fainted due to exhaustion, both physical and mental, but Gunko was torn apart, with her missing her hand, her torso, and legs, leaving only her head, but her regeneration suddenly started, which returned all of her physical wounds.
