4 years had passed since his battle against Fubuki and that fight was unforgettable, making him think of fighting someone like her mother or even every single unit chief of Anti-demon corp in the future.
In this time frame he took some break and concentrated on building the foundation of his martial art and abilities where he is able to see through 5 seconds into the future and maintain more clones than before.
He is also able to use more [ Limiter Removal ] due to his body maturing and developing into a prime Viltrumite but still far from the full fledged Viltrumite in their prime.
In terms of his swordsmanship was able to slowly master it and even tried [ Sun Breathing Technique ] that was in perfect unity with his [ Shadowed Blade of the End ].
He hasn't grown past his Asura form believing that he'll gain Six armed Vijra Asura, Mantra Asura, Destroyer Asura and finally Asura the Destroyer. Though, the power needed is so incredibly vast that it would be impossible in the world he was in.
As for his Mimicry, it was annoyingly difficult to master and he hasn't found the time to perfect it. He manages to find that he is able to copy in exchange for his strength meaning he would be sacrificing his stats for a skill. For example, his technique would become duller due sacrificing his stats for a skill and depending if he chooses to only have it for limited to out right steal it permanently.
The difference between copying and stealing is that the former would be at its most basic state while stealing would gain what the person gains from his experience of using the ability. It was an absolute cheat but believe can't steal those that have resistance or can shut his ability.
Regardless, he is a powerhouse even without these skills.
Yuuki was currently in his class within the Public High School Kaminoge as the Students were cleaning the classroom. He was only there because of his promise to her sister and parents who are still overseas but do provide things for him even though he could buy any material things in the world without losing much.
He had grown splendid having the same physique of Garou result from his training and had overgrown his hair, keeping it in a man bun.
Yuuki does enjoy the company of his male friends who were currently cleaning the room while he did the same since it also helps in his concentration and state of mind.
"Dude, are you going to meet up with those girls?"
One of his friends asked, knowing Yuuki was one of the most popular guys who is amazing in sports and study but the only thing that people say bad about him is his always beating anyone who challenges him.
"No, I don't like them."
Yuuki bluntly answered that they were too weak for his taste not because of their ability but their will and desire to get strong. He once beat a fat rich girl who was entitled because of her background and incredible power that he mimicked after beating her in a fight. It was the ability to manipulate probability that increased her luck exponentially.
He outright stole it when he got the chance and her parents tried to sue him only to realize the kind of power and influence he had stopped forcing the girl to move to another country.
Yuuki rarely copies ability since it takes a portion of his power away to gain the ability permanently even more if it's powerful ability. Yuuki only chooses useful powers that he sees extremely useful and within 4 years gain only 2 permanent abilities that he stole were [ Transmutation ] and [ Bio-Absorption Replication ].
This made his progress over the 4 years slowly that if he didn't do this would have been a lot stronger than before However, they were worth it as [ Transmutation ] allow him to alter or transform matter, energy, elements, objects, beings (animals, aliens, mythical beings, etc.), concepts etc into anything else, either completely or partially, permanently or temporarily.
This is all dependent on what he knows and materials that he has. A perfect ability with his intellect giving him more chances in making materials that he needs in his experiment.
On the other hand, the second ability allows him to absorb and replicate any matter and energy. They can draw any material or force into themselves, making it their own.
He can then replicate as well as manifest the properties of whatever they have assimilated into their system. They can also manipulate, augment, and alter what they've absorbed.
The properties of the assimilated energy and matter are also encoded into the user. This allows him to manifest the aspects of anything they've previously consumed instead of having to constantly absorb it. Basically Tamaki's ability from my hero academia.
"Still do you really have to beat her? I'm surprised you still have a great reputation even now."
His friend remarked in amazement that Yuuki managed to beat a girl who has an ability. Yuuki shrugged it off and finished up where he joined his friend to head home. He thought about the events that are going to unfold soon and how his action will affect it.
'I could remove all the problems right now…'
Yuuki was immensely strong believing he can even fight the current commander of the Anti-demon corp but if she's stronger then the better.
He does like a good challenge and even at this moment sealed his power using the wristband he wore that suppressed his power even further than before but once he removed it then his power would skyrocketed.
He has a nagging feeling that he is not yet the strongest in the verse and this makes his heart more excited to see that challenge in the future.
"Though, if things go according to my plan everyone benefits in the end."
Yuuki thought to himself and expected that it would make everyone stronger than before. He had a lollipop on his mouth when the surroundings began to change and was unfazed when he found himself in another dimension of Mato.
Seeing this unfold caused him to crush the lollipop he was eating as he grinned excitedly knowing that he was near at the start and been watching her grow behind the scene. He does find her resolve and will to get strong was the most admirable thing.
Yuuki does find it creepy how he keeps on spying on the future girls but this is also a way for him to keep them safe and go all according to his plan. He heard his phone ring and notified the emergency as Shuuki appeared behind him.
[ Renewal Taekwondo - Arang ]
He exuded an elbow strike that blew the shuuki away as planted his feet into the ground taking deep breaths gathering strength into his feet.
[ Renewal Taekwondo - Hwechoock ]
Yuuki performed a roundhouse kick producing a force that obliterated the rest of the Shuuki. He exhaled deeply then held out his hand taking out a sword having made his own inventory on his bracelet.
"It's been 2 years since the last time I've hunted. Let's see if you still remember me."
He said while the Shuuki kept on coming while Yuuki remained calm began to practice his [ Showed Blade of the End ] easily slicing through them.
"To Be already under attack lady luck isn't on your side...What happened here"
Yuuki looked and saw a woman riding a Shuuki and exhaled a steamy Breath. She was dumbfounded to see the shuuki having been sliced to pieces by the man before her and couldn't help being surprised when she looked at his face, having a sharp gaze that screamed strong like a demon.
"Are you a Member of the anti-Demon Corps?"
Yuuki knew who she was but wanted to make sure since he knew that she should be in the area. Yuuki inspected her appearance of a beautiful well-endowed young woman who has silver hair which extends up to her thighs, her hair has bangs on the side of her forehead, in the center while two chunks reach her shoulders and pink eyes where her eyes appear slit.
She is often in her Anti-Demon Corps uniform, consisting of a navy blue militia tunic, cap that has red highlights, white gloves, a short skirt, thigh-high boots. Additionally, Kyouka has unique accessories on her ears that resemble flat, blue, curved horns that stick up from her hair.
"Y-Yes I Am the Chief of the seventh unit of the anti-Demon Corps Kyouka Uzen Rest Assured your in Safe Hands"
Kyouka awakened from whr shock and stuttered wondering how a man was able to fight against Shuuki while Yuuki smirked at her remark.
"No Need These are far too weak to hurt me."
Kyouka wondered if he was arrogant or confident and wanted to interrogate him when they heard rumbling until they saw A Horde Of Shuuki running at them.
"Guess we have compan—"
Before he could finished was grabbed by Kyouka as they ran on top of the shuuki Yuuki rode the Shuuki as Kyouka charged and killed the Shuuki in front of them as a Shuuki appeared beside her.
Yuuki frowned that his senses had dulled a bit ever since he took the last ability. Though he was holding back quite a lot does find it annoying. However, he didn't let it get to him knowing that it was better if he was weak again so he can check his weakness like what happened to Mori Jin in God of Highschool.
"Dodged to the right."
She said the reaction time of the Shuuki was slow as she jumped and cut off its head. Kyouka then pulled out a talisman and stabbed it as a barrier appeared
"I Formed a simple barrier and didn't fret."
She showed a reassuring expression seemingly in deep thought looking at Yuuki feeling like he knows him somewhere unaware that he was the reason why he wanted to get stronger and have his revenge.
Ten years ago when her village was ravished by Shuuki, she thought her life was about to end when that person arrived and carried her to safety.
"Yeah but I don't think it will last long."
He remarked looking at the shuuki trying to destroy the barrier then glance at Kyouka who was having an inner turmoil.
"I could make it somehow if I were by myself... My peach's blessing... It's a real failure of power even for me."
She thought herself envious of the people around her who acquired amazing ability after eating their peaches, which is certainly something she didn't expect.
'Even if you're strong yourself, Kyouka, your power is kind of…'
'Becoming the commander is a dream that couldn't be more far off.'
Her memories recall the remarks of the people that saw her ability.
'Screw that. I'll definitely lead all the other chiefs. I WILL BECOME THE COMMANDER!!!'
She thought herself having decided whatever it takes would do it to ensure achieving her dream.
'I've no choice now I have not yet verified that med wouldn't be of use but I have to make up my mind'
She looked at Yuuki making up her mind while Yuuki saw her look at him realizing what she was about to do.
"What's your name?"
"Yuuki, Yuuki Wakura."
"Yuuki, there is a way for us to get out of here but you're going to have to do a part of it too."
"Yeah, so long it helps then sure why the hell not."
Yuuki said didn't feel worried about becoming her slave when the reward is something else but also he would gain the forms that will be great help for the future while Kyouka smiled hearing his reply and said.
"Well said….then become my slave."
"Slave? What do you mean by that?"
He crossed his arms while Kyouka was certainly surprised by his calm reaction and quickly explained her ability.
"My power draws out and makes use of the strength of the living beings I enslave."
"Oh So that's your peach ability"
"If you yourself are strengthened, we can escape from this alive."
Yuuki is then pushed by Kyouka and sits on top of him. she's at the top of him. She then grabs Yuuki's neck and pushes him down.
"You said you'd help to save us both, did you not."
"I was expecting we could fight together but you guess you had other plans. Alright let's get this over with."
Kyouka wondered why he was this accepting of the situation but it was convenient for her and said
"Good, now IT'S TIME TO SUBMIT."
Kyouka shoves her head into Yuuki's mouth, surprising him that he'll kiss him rather than make him kiss her fingers like the canon. He was able to taste her lips then a surge of power flooded into him and was engulfed in bright light.
[ You have acquired Temporary skill "Monster Slave Form." ]
As the pillar of light shone and chain shot outside the barrier along with the light. When it died down to see Yuuki in his slave form Chains Of Eternity "Slave". His new form appeared like a smooth white-skinned muscular humanoid Shuuki with a horned canine-esque face, with various red tribal markings across his back, shoulders, and chest; dressed in a pair of ballooning pants common to samurai, and black leather straps on his wrists.
