3 Pm, Japan, Mato
It had been quite the routine for Yuuki and Kyouka to train and improve their relationship through her ability even though it might be a peculiar way. He was in his [ Slave Form ] considering it a way to restrain himself while also bettering this martial art. Shuuki surround them yet through their combined effort easily demolish against their adversary showcasing their skills and power.
Yuuki glances at Kyouka as she dances through the hordes of Shuuki expertly utilizing her swordsmanship that had combined with [ Total Concentration Breathing ] and produces a [ Breathing style ] allowing her to fight longer and better than ever before. She wasn't born a prodigy but her tenacious nature always overcame her shortcomings.
He couldn't help but fall in love with her simply by watching her fight. It was different from the drawing that he had seen and the bond he shared with her was strong especially through her ability. Many individuals admire and love her from Himari and Shushu to Konomi and Tenka. Given enough time she can break through any walls that hold her back.
'She's truly a war goddess…' Yuuki thought to himself seeing her on top of Shuuki carcasses showing her dominating demeanor while he held onto a small Shuuki and used it like a bat slamming them against other Shuuki. On the other hand, Kyouka looked down to see her lover slaughtering the countless Shuuki that stopped and began to combine to become bigger.
"Good, the bigger they are, the easier they fall." She could hear him roaring unintimidated by the humongous monster before him that made appear like an ant in comparison yet this only made him more excited and exhilarating taking a deep breath than a particular stand.
[ Explosion Heart Released Fist ]
She instantly recognized the style as a technique that produces explosive power and rupture the inside of an opponent making it extremely devastating to fight against. Yuuki clenched his while the Giant Shuuki was cocked it's fist like he did and swung his enormous fist towards Yuuki who struck his fist collided against it and unexpectedly the forces that he had were stronger than Giant Shuuki causing its arms to explode and fall back from the attack.
[ Renewal Taekwondo - Axe kick ]
"Take this." Yuuki spun three times in the air before slamming his feet into the ground causing the enormous Shuuki to be split in half completely disintegrating his body.
Kyouka always found it amazing how strong and skilled he was but came to understand more why he is this strong because of his previous experience and wish. Though, he didn't underestimate him because even with talent there is only so much you can do without will and tenacity.
She fell for him because she felt indebted to him or rather his alter ego, Kuro Oni but eventually her heart shifted to him because of his encouraging words and kind hearted action despite how scary he appears at times. Kyouka only knew him for a few months, yet was already in relationships with him and a few other girls. She already knew it was a matter of time because part of her ability which is [ Lending ] allows her to share him with other people.
Her feelings were mixed up even after accepting their strange relationship but was able to learn it was because of the side effect of her ability and eventually found a way to ignore it. Despite all of it, Kyouka never felt neglected nor out of place when he had relationships with other girls, giving them time and attention even though he cheats by letting clones and machines to work on his other task but then again it's part of him there is no reason not to use it.
She learns about his past and how he had changed into a better person after experiencing happiness for the first time and having true bond. Kyouka is still shocked to find out his plans and realize the possibility of truly ending the Mato disaster one and for all. Though, it still feels annoying that two women got knocked up but didn't blame him much knowing what kind man he is and the person he slept with.
"I think we're done here. Let's head back." Kyouka knew that making him continue using his form would result in bigger reward and couldn't imagine what kind of deep latent desire that he has. Though, they already slept and done it doesn't mean she's fine with doing indecent action in the public.
"Yeah, I just finished up here." Yuuki gave a thumbs up and smile as Kyouka rode his back heading back to their dormitory.
"I've been wondering, where do you come up with these insane martial art techniques?" Kyouka took a long time to develop her own style that allow to dominate against Shuuki who are several times stronger than normal humans.
"Funny story about that….as I've told you earlier, I was a combat junky where I trained for the sake of fighting and thrill were the only thing that other hobby I had is reading manga and watching anime….hey don't give me that look." Yuuki could already guess how perflex she was to learn that a battle thirsty person like him to be interesting in children fantasy.
"My old world didn't have Shuuki and peaches so there wasn't that much supernatural going around." Yuuki told them a few things about his old world and how it got Kyouka into thinking.
"Was your old world peaceful without Shuuki?" Kyouka wanted to know if eradicating Shuuki and stopping Mato would truly bring peaches to the masses.
"Kind of, death is certainly lower but having true peace is inevitably impossible." Yuuki didn't try to filter it and frankly the world wasn't for him as it was too peaceful and annoying especially the westerner who couldn't identify what a man or a woman is nor can they take criticism without being offended like children.
Kyouka fell silent thinking about his world and was satisfied if the world became more peaceful if they could truly stop Shuuki from coming into their world. Though her action might cause the system to be shaken, Yuuki reassured he would help with the aftermath.
"I see, anyway, let's go back, where did you learn those techniques again? From manga and anime?" She changed their topic and Yuuki nodded to her question as he continued to run on all fours towards their dorm.
"Yeah, it's a great place of inspiration considering the creativity of the authors. I have a few more techniques that I want to learn and unlock but would take time." Yuuki was insanely strong but wanted to master more until he felt satisfied.
"I heard from Himari that your headband acts as inhibitors. Are you really holding back that much against Chief Fubuki?" Kyouka is slightly afraid that he might get hurt from constantly holding back.
"If you're afraid that I might get hurt or even die, don't worry, my life doesn't belong only to me but to all of you as well. That's why I'm not planning on dying anytime soon." Yuuki firmly said keeping in mind that he shouldn't live for the sake of his selfish impulses anymore.
[ That's right, you still need to take me on a date! ] Ivory said always worried that he might push himself too much in the bring of dying but she can't stop him because it's a violation.
'About that, we're going on a date after I visit my parents.' Yuuki said hearing her giggle in excitement having been with him the longest and know more than the other girls. She fell for him and was always by his side till the end.
"You better. Or I'll personally kill you if you die." Kyouka jokingly said while Yuuki chuckled hearing her words.
"Still, what technique are you attempting to learn?" Kyouka was curious what kind of monstrous technique he would develop.
"Do you know Kamiizumi Ise-no-Kami?" Yuuki already guessed that she knew because the person was the founder of the sword technique Shinkage-ryū.
"Of course I do, sword saint, don't tell me you mastered his technique?" She wasn't that surprised if he did after everything Yuuki had done.
"No, I'm no sword expert and I can't master them all. I only have Two sword styles that I've mastered, these being [ Shadowed Blade of the End ] and [ Hinokami Kagura ] or simply Sun Breathing." At the end of the day, Yuuki's true strength lies in his body and fist but only training with the sword to better his control and mastery of himself.
"The reason why I mention it is because he reached the state where he has opened the "door to martial consciousness". This state is a point which separates the realm of man from the realm of god; once open, he can apparently even control the beating of his own heart at will. A perfect control and mastery of the person and technique."
Yuuki explained recalling a series called Tenkaichi nihon saikyou mononofu ketteisen. It was a tournament style series similar to Record of Ragnarok. Kyouka hearing this was amazing and curious what kind of state he was talking about. She never got deep into the story behind Kamiizumi Ise-no-Kami life.
"It was called "Gate of Celestial Awakening." I'm unsure if I'm able to achieve it but there isn't any harm in trying." Yuuki recalled how Kamiizumi Ise-no-Kami able to enter it after dying and witnessing what seemed to be a Deity then coming back to life more powerful than ever. He became one with the universe similar to how he quoted in Vagabond Manga that his sword is one with heaven and earth.
"Isn't that similar to your [ Ultra Instinct ] state?" Kyouka recalled how his eyes would go inverted when the pupil turned white and the sclera became black.
"Indeed, but at a broader scale." Yuuki believed by truly letting himself follow the flow of everything then he would be able to control his own body and techniques to a higher degree that surpass even the strongest.
"Still, are you sure I can't use that technique?" She finds it convenient to enter a state of serenity. Kyouka does know [ Limit Removal ] and [ No pain ] technique but finds it better especially when she has Brain Limiter Removal technique but it takes a long incantation to be used.
".....I've told you how I do it right?" Yuuki has to put her in the death door and force her to enter [ Ultra Instinct ]. He wondered if he could turn that state into the Kure clan's Removal technique.
"Don't worry about me, I'm certain that I can handle it." Kyouka tapped his back to reassure that she's well capable while Yuuki thought about it.
"Alright fine, but if it doesn't work then just focus on improving your [ Total Concentration Breathing ] until it reaches a constant level." Yuuki said.
"I know, and I'm glad you agree. Now, I think we're already here. I can see the dorm from here." Kyouka looked afar and saw the towering dormitory and eventually the two arrived with Yuuki reverting back into his human form and Kyouka dragging him.
"It seems the reward involves Bath house again." Kyouka blushed but started to get used to and only blush when Yuuki give teasing smiled as the two entered inside where he noticed Kyouka stopped moving.
"...Take off my clothes." She embarrassingly said while Yuuki simply took off her clothes getting slightly aroused when she squirmed and her flustered expression. He slowly got them all and gave her a towel as they washed themselves more specifically Kyouka was washing Yuuki then submerge themselves into the water getting rid of the fatigue from fighting the Shuuki. Kyouka laid on his chest feeling the hidden leviathan underneath his towel that has yet to rise but the reward made her unable to stand up.
"Tell me, how strong are you right now?" Kyouka decided to break the silence, giving her lover a thought to think about.
"I'm not sure, physically and hax wise I'm certainly stronger than anyone else but I'm never certain. Regardless, my attack potency can easily level mountain range at least to an island level like what we did back on the Azuma estate." Yuuki doesn't know chief Varvara ability because he died before it was revealed and got to Konomi arc and the second time Ren used Canon Yuuki.
"Right….then if you remove your headband then you can destroy at least a large island." Kyouka is amazed at the thought of him unleashing that kind of powerful attack but someone like Yakumo Ezo has the strongest attack potency excluding the chief. Her [ Night Storm ] can easily destroy cities if not careful making it unfit to be used in urban areas because of the collateral damages.
"Most likely but I might not be able to make a stronger one at the rate I'm progressing." Yuuki made the materials using the best and most durable metal he could make even with his [ Transmutation(Stolen) ] would allow him to create insane metals without understanding their composition like adamantium and vibranium.
"...does turning you into my slave hinder you in any way?" Kyouka was worried that she might hold her back from improving but her thought was quickly answered by a warm embrace.
"Of course not, if anything it helps me even more. It serves as great training and helping you is another bonus." Yuuki already got used to his [ Slave ] form and felt a deep connection to those that use it.
"You're lying, shouldn't the reward be the bonus." Kyouka jokingly said and her lover laughed it off blowing her ear making Kyouka shudder.
"That's the special bonus." Yuuki flirted as it slowly escalated into short session until they finished and got dress heading into their room.
