It has only been a few minutes the fight has started and already caused massive destruction around them. The one of the sole reasons why Yuuki holds back is how devastating his power causes in certain places. Perhaps, in the past he wouldn't care but his nature had changed.
In the words of a Vagabond, "All truly strong people are kind." And "A kind man is strong not because of his deeds or accomplishment but from a fact he has known cruelty and violences yet still wishes to be kind."
Yuuki matured yet never lost his fangs that he had continuously sharpened. He stared down Killer Fang who did the same preparing for their next move.
The two then vanished and appeared at the center as they did a cross counter where Yuuki kicked Killer fangs head and was just by a powerful blow from his fist.
[ Renewal Taekwondo - Hoe Grab ]
He use his legs to grab Killer Fang's arm and held it into place where it couldn't counter when Yuuki added another attack.
[ Renewal Taekwondo - Spinning Top Kick ]
Killer Fang shook upon the impact resounding through the air as he shot him across the plane where Yuuki stepped into the air then propelled himself toward him. He took deep breaths causing ripples around then pumped his heart increasing power.
[ Ripple + Explosion Heart Released Fist + Renewal Taekwondo - Mach Punch ]
Having mixed a lot of power into his martial art that mitigated the weakness and went on without wasting any energy inhibited by his headband.
[ Monster Calamity God Slayer Fist - God Slayer Rainfall Strike. ]
The two rain down a flurry of punches that causes it to appear as though they had multiple arms consecutively clashing. Blow after blow their fist crushed with another where the recoil causes their hands to feel numb with Yuuki coughing blood.
His whole body was cracking and aching where the pain spread like wildfire where every exchange felt like hitting a metal. Though, this only compares if he had normal human strength.
[ Renewal Taekwondo - Lowest Hwechock ]
He dodged the attack by ducking to the ground then did a 180° spin sweep kick that is parallel to the ground aimed at the Killer fangs feet.
[ Renewal Taekwondo - Dragon Catcher ]
Yuuki then does a Hoe Grab and jumps up high while holding Killer fang's neck tightly while spinning at high speed, then Killer Fang is dropped onto the ground head first.
[ Monster Calamity God Slayer Fist - God Slayer Claw Slash ]
Killer Fang managed to flip its body landing on its feet creating a crater then took a stance where Yuuki planted his feet into the air and propelled himself forward. He dodges the claw slashes then cocked his fist clenching it tightly.
[ Destructive Death - Crushing Type: Ten Thousand Leaves Flashing Willow ]
Yuuki delivers a powerful downward punch that sends a large shockwave into the ground which expands outward and witnesses Killer Fang motion its hand drawing a circle that makes him go wide.
[ Whirlwind Water Stream: Roaring Aura Sky Ripping Fist ]
He instantly used every ounce of his power to not get hit and used his precognition where the shockwave of Killer fist grew exponentially as Yuuki then said.
"Bastard actually overwhelming me…"
Yuuki took deep breaths while they moved across the plane while Ren watched in shock and amazement but overshadowed by frustration and annoyances.
'They're speed and power are below mine yet able to exert this amount of power!? Impossible!'
At the basic attribute and overall power then Ren outclass Yuuki and Killer Fang several fold yet her arrogant and overestimating herself was her downfall. She never lost before and always displayed the highest degree but Yuuki is different.
He lost and lost and lost and lost until he won. Yuuki is a natural born fighter due to his tenacious nature and adaptability. Ren was able to stand up but knew getting in between them would be dangerous.
'I'll make sure to discipline him the next time I get the chance!'
Ren vowed watching the fight where Yuuki was getting more and more hurt yet his eyes were burning where his eyes shone. He could feel his mind dripping even more, succumbing into fainting only for him to slam his feet on the ground causing the rubble to shatter because Killer Fang fell while Yuuki changed his stance.
[ Cross Fang Dragon Slayer Fist ]
Yuuki was growing stronger releasing a massive power where his strike and attack reached newer heights. This is due to the fact that he has the same trait as Metal Bat. The burning power of a Fighting Spirit where he will get stronger as the fight continues.
Killer Fang was getting overwhelmed trying to counter his attack only to be easily outmatched. Yuuki had something that his opponent didn't have.
[ Monster Calamity God Slayer Fist - God Slaying Rippling Palm. ]
Extending his hand and turning into a shredding attack where it mixes the [ Whirlwind Iron Cutting Fist ] and [ Koei Style - True Rakshasa Palm ]. Killer Fang was growing weaker and weaker as Yuuki placed the final nail on the coffin.
"Thanks for helping ascend even further but this is the end."
Yuuki took a stance where his hand was inches away from Killer Fang, extended his four fingers then strike the abdomen of his clone where it rippled through its stomach making a vortex before it return to normal.
[ One Inch Killer Punch. ]
The thundering explosive impact of the attack cause Killer Fang to cough releasing the remaining air in it's diaphragm before it zoomed into the air traveling in blinding speed and slammed into nearby mountain shattering it's walls. Yuuki exhaled feeling relieved, sensing that Killer Fang was finally knocked unconscious.
"Gaahh!!"
He fell into his knees having faced the backlash of getting grazed by the [ Whirlwind Water Stream: Roaring Aura Sky Ripping Fist ] and having use [ Limit Removal ]. Yuuki might have easily won by removing his headband; it would result in him not discovering a few more things about himself.
'Killer Fang is actually able to create his own technique on the spot. I almost got overwhelmed by them.'
Yuuki controlled his breathing, fixing himself in order to stand up while he sensed Ren arriving having recovered and fixed herself retaining her elegance and authority looking down at Yuuki who was panting and said.
"Hmm, you did an amazing job serving me."
She kept her posture in a manner that still viewed herself as better than Yuuki which was not a lie and merely overestimated herself.
"Well, your fight was very good. Now, let's give you your "Pet" Reward, Yeah?"
Yuuki raises his eyebrow knowing that she made a mistake and that Kyouka and Nei had been doing the only reward that they would give. He sighs and sees her begin to remove her belt.
"...Hm?"
She stared blankly confused about what was happening while Yuuki was too busy recovering. Ren would soon get her second Humiliation.
==========
Ren Yamashiro, at a young age she excelled in everything, always performing higher than any of her peers where a great future was set for her.
'I would naturally get first in mock exams.'
Ren recalled her youth when she always surpassed the competition with her intellect and mind.
"I'd win a sports competition.'
Her memory shifted at the time when she held certificates when she participated in kendo when she was in high school.
'And I'd always give my all as the student council president.'
Moments when she was led by her fellow student showing that even before becoming commander she has the skills to be a leader and authoritarian figure. In a certain country at a certain place, Ren hovers in the air surrounded by a squirming body.
"She dealt with all those ability users so easily…and she was still holding back, ms.president."
Said by a woman to a blonde middle aged woman looking at Ren sweating and thinking about something then said like madman looking at the skum
"Trying to reach heights, humans have walked while looking at the heavens. And at the end of that journey, they have arrived at you."
She said looking at Ren with reverence and admiration as well as a shimmering light of hope seeing her as if she had the entire world behind her.
"Life's Apex, "Ren Yamashiro" Earth's answer, "Ren Yamashiro."
Ren smiled hearing the praise she received and enjoyed every moment of it getting an ego boost. The memory was clear to her and thought.
"That president gave me a variety of such compliments."
She has always been praised and revered all her life that it blinds her. Though, Ren has the right to be but this is where her failures come. She cannot accept defeat.
'For me to face this…'
At the present, she was removing her shorts while Yuuki watched it unfold.
"So your reward is not petting, but This…."
She removed her shorts then continued to strip and said.
"I thought you were a cute dog but you're just…Beast.*
Removing her shirt revealed her stocking and black bra while looking at Yuuki with great disgust who merely smiled then said.
"If only you listen then maybe this won't happen."
"You…"
She glared at his words but knew it was true that if she took more time learning about it then things won't happen the way it is now and immediately tried to use her power changing her mandala in her eyes.
'I can't cancel this foolish behavior with my ability. When Kyouka and I were experimenting with her ability using a Shuuki…I could undo the slave transformation but I could not undo the "Slave contract itself ". I assume this follows the same principle…'(Ren)
Ren started walking towards Yuuki deeply thinking about how to escape doing the humiliating action.
'Eternal chains "Slave" is a more special ability than everyone gave it credit for.'(Ren)
She then was surprised when she suddenly went on all fours walking towards Yuuki who was just looking at her, which annoyed her.
"Is this Still not over?"
"Don't know, unless you get control of your body then nope. It won't end unless I receive my re—"
It was then Ren suddenly got up close and licked Yuuki's cheek.
"—Ward."(Yuuki)
Her eyes widened in shock and horror that her body would do something shameful then her head seemed to rub against his face and lower her head in front of Yuuki.
"Just why…am I on the receiving end of the caressing!?"
"Relax, it's not the end of the world."(Yuuki)
She glared at him then Yuuki didn't hesitate to pat her head much to the humiliation of Ren. He felt how smooth her hair was and caressed it tenderly so that even Ren felt how warm his hands were.
"You're supposed to be the dog…."
Her face was flustered as Yuuki rubbed his hand on her cheek, squishing it, treating her like a dog and somewhat thought that she looked like Shiba Inu. Yuuki resumed by rubbing her hand while Ren continued to complain.
"Do you understand!?"
Yuuki simply ignored her and patted her, surprising her.
"FWAH…"
He didn't stop there and caressed her back, increasing Ren's humiliation.
"You're caressing me without holding back…you beast"
"Yosh yosh…"
"Don't yosh me!"
Ren angrily exclaimed then suddenly felt she had regained control of her body and didn't hesitate to move.
"I can move! It's over!"(Ren)
However, Yuuki's hand slipped into her bra and the moment Ren stood up revealed her breast to Yuuki much to her embarrassment. Ren glared at Yuuki and tried to attack him only for him to vanish and avoid her attack.
"You…"
"Hey now, shouldn't you worry about getting dressed than killing me?"
Ren looked down and immediately covered herself, glaring at Yuuki who shrugged it off as he took out a lollipop and the commander got dressed.
"You, how are you able to win? You're obviously weaker than me and it's clear you didn't use your ability."
She wanted to learn more about him and ensure she won't make the same mistake as she did.
"Fighting spirit."(Yuuki)
He lazily answered unbothered, further explaining that only annoyed Ren and said.
"Fighting spirit? What is that?"(Ren)
"If you haven't lost then you won't know about it nor will you be able to gain it."(Yuuki)
He simply said much to Ren disappointment and wanted to know but sense Kyouka was getting closer arriving to see the aftermath of the fight and was shocked to see a small ravine and crater. She was panting heavily since she had chased after them.
"You're all right…"(Kyouka)
"My form…was more than expected. You have to train him more."(Ren)
"Also, that berserk state….is dangerous."(Kyouka)
"No need to worry about that."(Ren)
She looked down at Yuuki giving an imposing glare then said.
"I'll make sure to thoroughly discipline him."
Yuuki simply stared at him and flew into the sky leaving a burst of air from her propulsion. Ren was flying in the sky recalling what had happened earlier from her bitter defeat to her humiliation causing her to grit her teeth in frustration.
"Uuuuughh!!!!"
She screamed out as she got out of control and crashed into the ground but was perfectly fine beside her face was completely red and said.
"Yuuki Wakura…"
