[Rikubetsu, Japan, Esper facility branch]
~Day 124~
Don't know how it started but one thing for sure was that, after the first Esper battle of Kaido after a long time, the scientist decided to let him fight against other Espers who would sign up to fight him
The reason for this was that not only would Kaido battle experience improve, the scientist in return would be able to see flaws in their adjustments
Per usual after they Injected the yellow liquid that made Kaido twitch on spot, they would in turn test his stress resistance, then after that he would undergo battle simulation
The only problem was that there is a high possibility of death whenever someone lose this battle cause of pride or desperation
For some reason Kaido has no favorable impression on the scientist, due to them he lost the meaning of life and day by day get tortured, at times he would be forced to eat some drugs that they said would improve him
He clearly remember the one time when he ate a drug, he was in turn paralyzed for one whole day cause of it, the fear of not being able to move was apparent in his memory
But since he couldn't do anything with 90% of his power being restricted, he in turn would just simply imprint on his.memory the faces of the scientist who did him wrong and vowed to get his revenge
But until that he was completely at their mercy
Currently he could be seen hiding behind a boulder after jumping behind it the moment the opponent made his move
For some reason Kaido felt biased on this situation as the scientist actually tweaked the tables as they released 50% power output on the enemy, while he will only get 10% released power
Such situation was really hopeless, what's more was that the opponent could control machines with a thought of his mind, thus they provided him with Android's and Mecha that often can be seen in fictional movies
As the rattling from a sub machine gun kept rolling towards him, some of the robots actually tried to circle him to catch him off guard
Without hesitation or regard for his life at all, Kaido immediately applied psychic barrier and took a quick peek behind the boulder before pulling himself back to cover
As expected the moment he did that the opponent bombarded him with firepower as they easily broke his barrier after the fifth bullet hits his psychic barrier and manged to graze his cheeks
After doing that Kaido started deliberating his situation
"1 Esper, 2 Mecha, 4 Android's both split from left to right in pairs"
Surprisingly his quick analysis started to kicks in as this was some result of having his brain tweaked for a quite a while
Due to experimentations Kaido lost all emotions and regard for life, followed that his quick thinking process helps him survive dangerous situation
At some point he overheard some scientist that the reason why the three primary scientist were spending a lot for him was that they wanted the strongest Esper to be born, in fact they also wanted an Esper who would turn into a war machine and make any type of weapon useless infront of him
With that expectations for him, many things happened to Kaido that made him suffer so much that resulted on the current him
The moment two Android's appeared beside him, he quickly pushed himself off the ground as he stayed low and tackled them at it's knee
Seeing this the Android's tried to retaliate by doing various combat method and some guns when suddenly Kaido made a full 360° front flip landing on their shoulders
With a grin Kaido held the Android's head before pulling it out like it was nothing, in contrary the reason why Kaido was able to do that was because he used psychic energy to strengthen his muscles to be able to pull something off without any problem
Very quickly he jumped up the moment the other Android fired some hail of bullets at him and threw the head of the previous Android straight through the assaulting Android's chest
As he landed safely two more Android's appeared at the other end and saw him, without further ado they fired at him
Naturally Kaido made a dash to avoid the hail of bullets at him, but nonetheless two more hail of bullets came from the Mecha infront of him
Quickly he used the boulders to cut through the space in between them and often times apply barrier on himself to delay the damage that he would take by a mile
After lounging at one boulder he immediately went prone to avoid some surprise attacks and rolled to his right to avoid another volley of bullets
With a push from his hand he made a dash behind the cover as he stumbled forwards and jumped sideways as he avoided some bombardment of planted bombs
Applying psychic energy on his hands, Kaido dashed forward without any restraints and slid under one Mecha appearing beside the Esper and quickly summersaulted at another angle as the previous one was being showered with bullets
After taking his stance Kaido hurriedly punched the Esper as at the same time opened up his palm and letting the Esper experience a flame burst right infront of his face
With this even if his power was only 10% released then it would still be enough to deal with a fatal damage
After the initial attack from him the Esper who forgot to apply a barrier on time was burned to death cause of one simple attack
Yet another one died cause of him, but for some reason Kaido felt no emotions right after killing someone unlike the first time he killed a person
Right after that rumors spread across the facility thus causing everyone to hesitate to bet on their life when fighting him
This continued on until all people started to avoid him due to fear of being killed emotionlessly
*******
~Day 153 (5 months)~
With the initial laid out result, the three scientist who primarily handled him we're promoted to a higher degree as two of them were transferred to a higher facility for a new project, while the other one was left to take care of Kaido's needs
Apparently they really are doing a good job at that by throwing him inside a room that even light had a hard time penetrating through it
Due to that Kaido was really left I to the dark with only cold walls on the right and a black one sided see through glass on his left
During this time of the night Kaido was left freezing out as the coldness of the night permeated through his skin
At the same time there was also a female scientist who always brings her daughter with her when working
Kaido deducted that the female scientist was perhaps a single mother, but in the end it doesn't concern him
With a deadpan like eyes he was left to starve while freezing through the night
*******
~Day 154~
The next morning as usual the female scientist was together with her daughter as they checked out the facilities when suddenly they saw Kaido behind a black screen window as he laid down on the cold hard floor
Of course Kaido couldn't see them but he could feel some presence that was lurking behind the black one side see through glass
Seeing his deadpan eyes that are voided with life and his skinny, brawny body that was apparently malnourished, the Female scientist gasp in surprise as she quickly left with her daughter
During the afternoon the little girl was actually playing along the hallway as she suddenly stumble upon the locked up Kaido who was currently fiddling on his collar
Surprisingly she approached him and touched the glass, naturally Kaido took notice of that presence as he glared at the girl with his red deadpan eyes
Due to maybe being accustomed of killing someone, his eyes somehow permeated with killing intent, but the girl somehow didn't took notice of this as she smiled and asked him
"Mister! Do you want to hear me sing?"
Of course Kaido didn't reply but kept fiddling on the collar which was getting rusted due to time and sweat
It won't be long until Kaido could get out of his current situation
But for some reason the girl kept singing without any reply from him
(Girl child singing:
London bridge is falling down
falling down
falling down
London bridge is falling down
my fair lady)
Hearing that even Kaido was stunned for a moment as he interpreted the meaning of the song based on his perspective
Surprisingly he found it quite interesting so even if the girl left, he would unintentionally start to sing it on his own
*******
~Day 160~
As night falls for that particular day, the security during that time turned lax as the original guards were replaced by night guards during their shifts
From the darkness one could hear Kaido singing London bridge which quite scares people since it's the middle of the night and Kaido was singing it slowly like a song from a horror movie
With a clink! The collar on Kaido suddenly snapped as it broke apart easily when Kaido tried to remove it
After standing straight, Kaido could feel the nostalgia of having his powers released at 100% after all this time
With a word he finished the song, which at the same time begun the opening destruction
"My fair lady..."
With a grin and a stomp the whole facility exploded as it causes numerous deaths due to his rampage
*******
After that scene of memory, the whole place turned dark as two entities formed up in the middle of the darkness
One was Kaido who was clad in white hollow light much look like a spirit, while the other one was like a disgusting greyish creepy aura that originated from the cursed sword
"It's over huh! What do you expect me to do after seeing all that?" Asked the white entity Kaido
(I don't expect anything from you, better yet im Surprised to see you not panicking upon seeing me) said the other entity
"Why would I? I was already aware of your presence long before I departed away from Ingra Kingdom" said Kaido
(I see... . .)
"Tell me how do you like to die for infiltrating my body?" Asked Kaido
(Please do your worst... . . But first let me ask you... . . Do you even know who you are?)
"Do I even know?... . . What kind of truck question is this? Of course I'm... . ."
But for some reason no matter what Kaido do, he just couldn't remember who he was, to be more precise as he talks with the other entity he could feel that his memory was getting wiped clean for some reason
"What did you do?" He growled
(I see that you have noticed it, your quite slow on the uptake, but nevertheless this only means one thing)
"....."
(Your too tired to compete against me in control of your body)
Hearing that Kaido broke into a grin
"Hahahaha! So your doing exactly as the same as that damned Celestial did to Hibiki?"
(More or less, yes)
With that Kaido tried to step forward but suddenly noticed that he was so long slowly unto the darkness below
"Wa... . . What is this? What the hell!!! What did you do?" Raged Kaido
(Angry? Took you long enough, but apparently as the Victor of this mind battle I'm having you erased from existence)
"!!!"
(With that I'll be the solely owner of this body, and freely roam this world once more without any restraints)
"You... . . "
(But no worries I'll take in charge of everything and as a respect for you, I'll find that damned vampire who almost destroyed this body and kill him myself... . . So leave everything to me)
As the cursed entity said that, Kaido somehow calmed down as he was slowly getting pulled down by some black hands that is slowly engulfing him
"Don't think you've won"
(!!!)
This time the cursed entity was the one who's surprised
"Even if I'm engulfed by darkness and erased for all eternity, I'll still return... . . remember we're not done yet, I'll properly deal with you when the time comes, so enjoy your freedom while it lasted cause when I return... . . I'll destroy you completely" threatened Kaido
(I'd like to see you try)
"Hahaha! Expect it bastard! Hahahahahahaha!!!"
With that Kaido laughed hysterically before glaring at the cursed entity with his red eyes for the last time and being erased by the darkness that swallowed him while thus destroying every last bit of remaining of him
********
[Demon Continent]
Back inside the prison cell as the laughter coming from the guards and some rented succubus that are serving them
Laughter and merry permeated the air as they drank their fill with red wine
Due to their negligence they didn't even notice that for some reason something else was now in control of Kaido's body as dark and oppressing aura slowly destroyed the magic circle that was restraining his powers
Apparently such trait was can be founded on cursed sword which is named as the corruption skill
As theagic circle broke apart, the cursed sword who took in the name of Kaido can be seen stretching it's muscles after a long while as the glint of shine can be seen on its hazy black eyes
Because the cursed sword doesn't have a name, it apparently took Kaido's name as it's property for convenience
"Alright! First off... . . Let's get out of here"
With that as the signal the whole prison base suddenly exploded without prior notice as it buried itself from the piles of rubbles thus granting the cursed sword a worthy opening for it's freedom
