I'm pretty sure this development is complete B*llshit but hey it's a fanfic and everything goes. Hope it isn't as bad as I made it out to be but whatever.
=========
Himari tried to forget what she was feeling, considering it was rather illogical and irrational to think her feelings would be attracted towards Yuuki. At first she thought this could be a deep gratitude to what he's willing to do and the profound words that push her through the challenges.
However, her thoughts immediately compare it to Kyouka and Yuuki having clear differences between how she felt. She couldn't share with anyone and had to continue to bury deep putting effort in her training instead but when she finally had time for herself would end up thinking about Yuuki. She could hold it anymore and was now going all in hopes of fixing her feelings.
She was embarrassed to look at him burying her face into his chest while Yuuki softly laying his face into her hair smelling the fragrance of her shampoo.
"Nothing that I know but judging from how you act, I can say that you've developed feelings for me. I'm not dense when it comes to this and you forget I'm a genius after seeing all the awesome shit I've done."
Yuuki is honestly unsure how she feels would act this fast and even with [ probability manipulation ] it shouldn't affect them this deeply as he only made it so that they have a better relationship. He concludes that without precise instruction would rely on what he desires most and affect his chance in them.
Perhaps it can be argued it was a source of manipulation but everyone even without ability can manipulate a person through their words and charisma only setting the line from their reason.
Yuuki desires them because he likes them and wants to protect them. He grows to love them even more when he gets to interact with them in person.
"Aren't you being too arrogant?"
Himari tried to ease the situation but the answers were clear and embarrassed that she did forget that he was a certified genius having invited their caretaker android.
"...still how can you be sure I have feelings for you when we have only known each other for almost two weeks. Was this a side effect of slave power?"
"I'll be honest and don't be alarmed because you still can decide for yourself—"
"Just get to the point."
Himari looked at him angrily, which was more adorable as her face was still flustered from having confessed that she basically started to have feelings for him.
"It is a passive ability that basically gives more charisma."
He further explains that he has unnaturally high charisma, or charm, enabling them to gain the trust and loyalty of others and win them over to their cause.
Charisma is a trait found in certain personalities usually including extreme charm and 'magnetic' quality of personality and/or appearance along with innate and powerfully sophisticated personal communicability and persuasiveness.
Though very difficult or even impossible to define accurately, charisma is often used to describe one's ability to lead, charm, persuade, inspire, and/or influence people.
The user is special compared to other commonly charismatic figures as their charisma is innately formed and effective for even the most disagreeable entities and allows them to bring the whole groups of individuals to their aid.
"....You're basically saying you're handsome with extra steps?"
"You said it, Not me."
"You…"
Yuuki smirked, making her blush before chuckling while Himari glared at him angrily until she deeply sighed, putting her head into chest. Enjoying the relaxing warmth that he always permeates.
"You know I was really harsh with you. I'm sorry, I guess Men aren't all the same."
Himari gave a sincere apology and Yuuki nodded pattung her head.
"I've always been great at judging character and knew you were more than meets the eye. But you should be careful because you kind of turned into the same people who hurt you when we first met."
Himari realized it the moment he mentioned it and began to reevaluate her views thinking that Yuuki opened doors for her and never felt this rush pouring into her heart before. She was happy for the first time in a long time and stared deeply at his lips until her body moved on his own and tasted his lips but this time it was her choice.
"...I can't believe that you made me part of your harem without me realizing it. This was your plan all along, wasn't it?"
She confronts him thinking that it doesn't seem bad to be with him when he had great qualities, especially his cooking that she loved.
"Ah, you got me there. Though, are you sure about this? I'm not forcing you and maybe your feelings will come to pass."
"....I don't know why I'm doing this nor willing to give myself to a man who will chase other girls' skirts."
"Hey, I told you that if I did that I'd consult the rest of my women first. Though, my sister isn't here but there's a girl before you, hey, how long are you going to stay there."
Himari was surprised when Shushu had her grand entrance, making the former blink for a moment and couldn't believe that she fell into his clutches.
"What!? When!?"
"It's a long story but….yeah, I agreed to be with him and sort my feelings for him. I guess it's been a few days during your training session we've been spending time together and it made my feelings for him grow."
They often spend time after their training as he had near endless stamina and endurance while also becoming more intimate exploring more about each other. Himari couldn't believe what he had just heard from Shushu knowing that she's been acting differently lately explains a lot.
"...you're such a fiend….how do you plan on spending time with us?"
"Depends on you, I'm always available, day or night. I don't really need sleep nor to rest."
"I don't mind taking the day and Himari can have the night for our date? Or we can have a double date cause I don't mind having Himari with us."
Shushu suggested while Himari was getting overwhelmed by everything and said.
"Wait, wait, I need time to think."
"Take as much as you need but I'm always here if you need company."
Himari nodded while Shushu excused herself as she would need to get ready as the next round was hers.
"Still can't believe Shushu is part of it, don't tell me—"
"No, at least not yet. It is clear she started to have feelings but still conflicted about something and wanted her to at least resolve it first."
Yuuki didn't want her to have the only reason in liking him is from saving her. Unlike Kyouka, the rest of them had time to get to know him and understand what kind of person he is even for a short time.
"How many do you intend to have anyway?"
"No comment on that, I don't want to jinx myself. Though, neglecting any of you would be the last thing I want."
He said thinking about spoiling her sister once they meet again since he doesn't know where she is at the moment and wants to find them later.
"...how far have you gone with Shushu?"
She innocently blush at the thought of them doing erotic sessions and Yuuki grew a smirk.
"Try guessing~?"
Himari heats up imagining the thing they could have done before hitting Yuuki.
"Stop teasing me and tell me."
"If you think I took her maidenhood then no. We mostly did some oral and fore—"
"Okay stop….how can you say those things without a filter!?"
"Hey you ask for it."
Yuuki shook his head while Himari couldn't help but imagine herself doing those things.
"Let's continue this later but one last thing, are you sure about not going back home."
Himari looked at him in the eye, softened her expression touching his cheek, noticing how troubled he seemed.
"Don't worry I'm going to stay here with the chief, Because she had helped me during rough times."
"That's a bummer, I was thinking of giving them a piece of my mind about what they did to you."
Hearing her remark saw him hundred times more handsome feeling that it was genuine and sincere. She couldn't help but take another kiss, licking his lips, surprising him yet welcoming it.
"Shouldn't we head back…."
"...No, let me have this. Pamper me more."
"Now you're just acting like a child."
"Who's fault is it? Now I will be yours soon, it's your duty to attend to my needs."
Yuuki thought about how her feelings were all over the place but clearly had the intention to be his now that things cleared up.
Later, with the entirety of the 6th and 7th Units gathered, Ginna Bizen announces the start of the second match of the Mato Exhibition Games.
Yachiho saw the two seem in a mess where her sister seemed more energized than before as if beaming and thought it has to do with her victory earlier while Yuuki noticed that she was slightly wet from their make out session earlier.
Yuuki notes that she was lewder than Shushu and quite the handful on her demand on where to kiss, showing her love on getting marked by hickey.
'I wonder if I could convince that slave to give me tabs on Himari.'
She thought to herself then saw him turn to her direction and wave at her with a friendly smile that she couldn't help by surprise and somewhat blush.
'He seems too dangerous for Himari to keep around….I should do something about it later. Though, as much as I hate to admit it, he was stronger than I expected.'
Yachiho didn't know what kind of landmine that she was about to step into once he got to know him. Meanwhile, Tenka called out Sahara to start the next fight.
"Sahara."
"Im Sleepy But I Guess I Should Go~"
She yawned while stretching while Shushu stepped forward enthusiastically having seen Himari glowing after her pampering from Yuuki.
"I'll Also Win!"(Shushu)
"Good Luck."(Nei)
Nei cheered her on whole Shushu turned to Yuuki and said.
"I'll show you what I'm capable of doing so watch me.
"I am and I know you'll do great."
She then approaches him and whispers.
"I'll Put In a lot of effort so make sure to properly express your Gratitude."
"Of course even if you lose I'll still show my gratitude~"
Shushu became fired up when she heard this whole Himari somewhat knew what they were whispering after learning their current relationship status. Meanwhile, Tenka took Yachiho and gave her some pom pom to cheer her colleagues despite her sour expression. Paradigm Shift user turned her attention to the fight and said.
"So you specialized In Close Combat,Why Don't we fight without using our powers?"
"OKAAAY~"
"I'll Be narrating the fight to make it more exciting."
Ginna announced while the two stared down at each other waiting for the signal.
"Start!"
"Here I go."
Sahara starts with a kick, but Shushu grabs her leg and forces her to the ground. Shushu attempts an elbow drop, but Sahara rolls out of the way and grabs her from behind.
Sahara then throws her to the ground with a German suplex. Shushu quickly got back up gritting her teeth.
"This isn't Over Yet."
"I'm Tired Already...Now! Let's Use Our Powers!"
Sahara complained, surprising everyone.
"Already!"
"But this was really exciting!"(Ginna)
"Whatever, Let's do this."(Shushu)
Tenka and Yachiho wonder "how many" Sahara will use, with Yachiho estimating one and Tenka three.
'Both can boost Their Physical Abilities using their powers this won't last long'
Kyouka thought to herself evaluating their powers while Yuuki noted that Shushu is using her ability to be straightforward and predictable.
'Note to self, train her. She relies too much on growing when she can shrink and it's not like her momentum changes.'
Yuuki decided to give her pointers once they finished and spoiled her too much with their intimate night together. He decided that it was fair for Himari to have turn if she wished and if not then Yuuki had free time in the evening to finish his project.
He does hope to finish the personal world before going to building his personal floating island inside hoping to turn it into a paradise. Yuuki puts it aside and continues to watch them as both of them use their power exploding in power.
"Paradigm Shift!!!"
"Mad Sheep 3!"
