When Sasaki was alive, he had never won a single match in his entire life. At his dojo, he was one of the weakest students and was outclassed to the point that even if he fought one of his fellow students
100 times over he would not prevail.
Sasaki trained for half a month, and
utterly surpassed the man who outclassed him to the point Sasaki gave the man visions of Sasaki cutting him in half. Sasaki achieved this both through muscle training, but also through using his incredible analytical abilities to fight the man
146 times over that half year.
After this, Kojiro would leave his dojo for many years to come and would train against all of the people in his dojo in
in his mind for 4 years and 9 months, eventually even eclipsing his
old master in strength, who before Kojiro left the dojo, previously appeared so strong to Kojiro that he was akin to
a tiger.
After this, Kojiro went on a long journey of fighting and losing against opponents. He would
face people that utterly eclipsed him in power and skill, and would proceed to train against all of these opponents in his mind until he had become strong enough to
win against them. In Record of Ragnarok lore, Kojiro
continued to lose until he had reached the absolute pinnacle of human swordsmanship until he died in his fight against Musashi
It is stated that after he died,
Kojiro continued to train his skills in heaven for over 400 years. Along with this, the contestants of Ragnarok on the human side are all summoned in their peak/their youth where they were at their most strongest, but, due to his everlasting training even after death, Kojiro's old, decrepit body was considered to be his
"golden age".
Now we will get to the actual fight between him and Poseidon.
As soon as his fight with Poseidon began, the man was able to immediately predict
18 exact ways Poseidon could end his life even though neither of them had even made a single move in the battle, a feat for his analytical abilities.
In the exact same fight, Kojiro's secret technique, the Tsubame Gaeshi,
allowed him to counter Poseidon, someone he had already imagined stomping him over 18 times before the God of the Sea had even made a single move, and he was even able to
make Poseidon look him in the eye, a God notorious for his ruthlessness, but also his under-evaluation of the human race.
Once the fight finally took off, Kojiro was capable of
dodging attacks that were much faster than him, due to the fact he had already experienced said attacks in his mind, as as soon as the fight had started, Sasaki formed
a perfect image of Poseidon in his head,
and faced off against the image countless times, allowing him to know all of Poseidon's possible attack patterns, and thus allowing him to avoid them even though they were much faster than he was. This technique is referred to as the
"thousand-image defense".
But, regardless of this, this was only an inkling of Poseidon's
true power, and the god eventually began to speed blitz Kojiro after getting partially serious, even though he was already much faster than Kojiro. But even with this, Kojiro's sword, which was stated to have stepped into the
surpassed humanity and
stepped into the realm of the gods, held up against Poseidon's onslaught via Kojiro predicting Poseidon's moves constantly throughout the exchange, allowing him to
evolve in response to Poseidon's attack.
But even with this, Poseidon was still able to out-skill Kojiro and
saw through the man's constant predictions, and even with this, Kojiro continued to
persevere through the onslaught, continuously evolving to suit the situation and the attacks coming towards him in order to avoid death.
Obviously,
Poseidon stomped him and broke his Volund.
It comes back through a Re-Volund so don't worry.
So, as usual,
Poseidon attacked and Kojiro countered it. But, what is unique about this, is
that he was able to perfectly copy the movements of his old opponents,
every last one, after countless upon countless repetitions of his fights with them in his mind during his 400-year training after his death.
And eventually...
He even began to
wound Poseidon,
multiple times even despite the God of the Sea previously absolutely decimating him! Sasaki's technique was so strong even, that by the time the exchange ended,
Poseidon was utterly littered with wounds.
BUT OBVIOUSLY,
Poseidon started stomping him again, moving so fast that even with his thousand-image defense, Kojiro literally
could not react in time to counter. Poseidon proceeded to make it EVEN WORSE by
covering the man in a
dome of attacks that were also exceptionally faster than his reaction speed, coming from all directions.
Kojiro was able to just
barely react, but, obviously, because Poseidon's dick is bigger than the Pacific Ocean,
he was still rocking Kojiro's shit to the point Kojiro felt as though Poseidon's strength was akin to
an endless abyss. That is how utterly outclassed Kojiro was in this fight.
But...
Sasaki was only getting started. As shown in the scan, he continued to counter Poseidon's attacks despite their speed and power, and it was even stated that all of these stomp-worthy attacks
only served to make the man
even stronger. That is how busted Sasaki Kojiro's analytics are.
He'd finally reached the Sea God in strength.
And with that,
Sasaki's awareness rapidly evolved.. He began to scan
even deeper, to the vibrations in the air, to the trembles of the Earth, to the point that he was stated to have begun to scan
all of creation at once, and finally stole the techniques of Poseidon.
After so long of getting stomped,
Kojiro began to seamlessly pass through Poseidon's attacks with newfound skill, putting on display the insane evolution of this ******. Kojiro's skill had evolved so god damn much,
that he invented an entire new technique that *******
cut Poseidon's arm off,
and he even did it AGAIN.
And finally, he killed Poseidon with his final Swallow-Tiger combo.
