At the training ground of the Anti-Demon Ninja Organization's Tokyo Headquarters Base, when Yukito followed Yatsu Murasaki there, he spotted a familiar figure.
Yukikaze, who had somehow already changed into a black skin-tight battle suit, was currently sparring on the training ground with a tall, well-endowed mature woman in her twenties who wore her hair in a high ponytail.
Yukito had no impression of the Anti-Demon Ninja big sister who was sparring with Yukikaze. After all, he had transmigrated to this world over ten years ago, and many of his memories from before his transmigration had long since become blurry.
Furthermore, the Anti-Demon Ninja of this world looked somewhat different from the various female protagonists in the Anti-Demon Ninja-themed works he had seen in the past.
Otherwise, he would not have failed to recognize Yatsu Murasaki immediately when he saw her yesterday at the Abandoned Hospital.
However, seeing that the Anti-Demon Ninja big sister sparring with Yukikaze also used Lightning Release ninjutsu, and that both her mastery of Lightning Release techniques and the power of her Lightning Release surpassed Yukikaze's, Yukito had a rough idea of who she might be.
"Onii-chan, have you already met Captain Asagi?"
"Onii-chan, have you officially become a member of the Anti-Demon Ninja, and will you be partnering with me on missions from now on?"
Yukikaze, who was receiving instruction from Uehara Rin on the training ground, caught sight of Yukito following Yatsu Murasaki out of the corner of her eye and instantly lost all interest in continuing her training.
Powerful currents erupted around her as she quickly retreated a few steps, disengaged from the spar, and ran straight toward Yukito.
Although Uehara Rin felt that Yukikaze should not be distracted during practical training, she had no intention of chasing after her and scolding her at this moment.
She had originally come here at Asagi's invitation during her free time to train and instruct newly awakened Anti-Demon Ninja.
In a sense, she served as a teacher to rookie Anti-Demon Ninja like Yukikaze.
Although Yukikaze could be somewhat impulsive at times, her strength among Anti-Demon Ninja of the same generation was undoubtedly among the very best.
While part of that could be attributed to the fact that Yukikaze's mother was Shiranui Mizuki, the Phantom Ninja who was once known as the strongest Anti-Demon Ninja alongside Asagi, it did not diminish Yukikaze's own talent and hard work.
"Yukito-kun will be my partner from now on, and we'll form a small team to carry out missions."
"Eh? Onii-chan and Senior Murasaki together...?"
Yukikaze had just reached Yukito's side, but before she could say anything, Yatsu Murasaki suddenly spoke, directly shattering Yukikaze's hope of teaming up with her Onii-chan.
"This young man is called 'Onii-chan' by Yukikaze. Is he also a member of the Mizuki Family?"
"I remember the Mizuki Family has always been sparsely populated. Did Senior Shiranui Mizuki have another child before giving birth to Yukikaze, or is he from a collateral branch of the Mizuki Family?"
After observing Yukito, Yukikaze, and Yatsu Murasaki for a while, Uehara Rin walked over with a curious expression and examined Yukito as she spoke.
Anti-Demon Ninja are usually born into families that pass down their legacy from generation to generation, because an Anti-Demon Ninja's power is not obtained through training like that of an Onmyoji or a Shinto priest, but instead originates from their bloodline.
Over the years, many Anti-Demon Ninja families have completely disappeared due to the loss of their bloodlines.
Teacher Uehara had heard about the Mizuki Family's declining numbers. It was even rumored that Shiranui Mizuki herself had been born through artificial means arranged by the Mizuki Family.
The appearance of Yukito at this moment naturally piqued Teacher Uehara's curiosity.
To be given the Mizuki surname, he was either a child secretly born by Shiranui before Yukikaze, or an adopted son-in-law, or someone directly adopted from a collateral branch of the Mizuki Family.
In this country, it is perfectly normal for a man to marry into a family and become its heir when there is no suitable successor.
In Teacher Uehara's eyes, Yukito was likely the child groom Shiranui had chosen for Yukikaze, and he seemed very much like a talented successor carefully selected from one of the Mizuki Family's branch families.
"Did Asagi really agree to let this young man become an Anti-Demon Ninja?"
"Why do I feel a power within him that is completely different from Anti-Demon factors?"
Teacher Uehara carefully observed Yukito and quickly noticed the Chakra within him, which was entirely different from Anti-Demon factors.
"Although Lady Asagi agreed to let Yukito-kun join the Anti-Demon Ninja Organization, Yukito-kun is not actually an Anti-Demon Ninja."
"Yukito-kun, this is Lady Asagi's friend and also Yukikaze's teacher, Uehara Rin."
"This is Yukito Mizuki. He was adopted by Senior Shiranui…"
As Yatsu Murasaki introduced Yukito and Teacher Uehara to each other, she was about to explain that Yukito had been rescued and adopted by Shiranui when he was young, making him Yukikaze's non-blood-related older brother. However, Teacher Uehara interrupted her with a knowing expression.
"The child groom brought home by Shiranui-san, and the future head of the Mizuki Family, right?"
As Teacher Uehara's words fell, everyone present fell silent.
Yatsu Murasaki and Yukikaze had not thought much about it before, but after hearing Teacher Uehara say it aloud, they could not help but wonder whether that had been Shiranui's true intention in bringing Yukito home.
If one were to say that Yukito had been raised as a groom prepared for Yukikaze, it did not seem entirely impossible.
"Stare~!"
Thinking about it, Yukikaze and Yatsu Murasaki unconsciously turned their gazes toward Yukito, who was standing off to the side.
Especially Yukikaze. When she imagined her beloved Onii-chan becoming her future husband, an indescribable feeling of shyness rose within her heart.
Yukikaze had long harbored a vague romantic affection for her Onii-chan, but she had never expressed it openly.
If Onii-chan truly was the groom her mother had prepared for her, Yukikaze felt she could accept it. After all, it would be her mother's arrangement, so how could she object?
"I say, Yukikaze and Miss Murasaki, can you two stop looking at me with those strange eyes?"
"I've never heard anything about being a child groom. Aunt Shiranui probably wouldn't interfere with my personal relationships that much."
Yukito rolled his eyes and spoke helplessly.
Yukito was not someone who was oblivious to emotions, especially not Yukikaze's feelings toward him.
He could vaguely sense her affection, but he had not yet figured out how to respond to it.
Yukito Mizuki was also very self-aware. He knew he was not the type of person who could devote himself entirely to one person.
Having finally transmigrated, and into such a somewhat broken two-dimensional world, he had already been very principled by not completely letting loose and wantonly spreading his hormones and semen among the beautiful, voluptuous older sisters and youthful, beautiful young girls around him.
Of course, he cared deeply for Yukikaze, his non-blood-related younger sister who had grown up alongside him. However, besides Yukikaze, he also had favorable impressions of Akiyama Rinko, Yatsu Murasaki, Aunt Asagi, Aunt Shiranui, and even Uehara Rin, whom he had only met today.
Yukito Mizuki admitted that he was simply lusting after the bodies of these beautiful women. Any boy with normal physical development and no issues with his sexual orientation would probably lust after the bodies of these beautiful, well-figured older sisters.
Because of this, Yukito could not honestly confess his feelings to any particular woman.
"In this day and age, there's no such thing as child grooms or child brides. Aunt Shiranui is very open-minded. She encourages me to pursue love freely."
"Hmph~~ I never thought of having Onii-chan as my groom either. Just thinking about it feels weird!"
"Luckily, Mom doesn't have plans like that. Otherwise, I'd have to think about how to refuse."
When Yukikaze heard Yukito directly deny the idea of being her groom, a trace of disappointment flashed across her eyes before quickly disappearing.
Pretending not to care, she let out a stubborn snort and spoke to him.
Although Yukikaze acted indifferent, Yukito, who had lived under the same roof as her for ten years, understood her tsundere personality very well.
From her expression, her eyes, and the tone of her voice, he could tell she was probably a little upset.
Fortunately, he already knew how to calm his sister whenever she got angry, so he was not particularly worried.
"Young man... I'll just call you Yukito-kun. Although you're not an Anti-Demon Ninja, I'm very curious about this new power you possess."
"How about we have a sparring match? I'd really like to see your strength."
Teacher Uehara no longer dwelled on the groom topic. Instead, she looked at Yukito with obvious interest and openly challenged him to a sparring match.
Although the power of Anti-Demon Ninjas came from bloodline inheritance, for reasons nobody fully understood, most people capable of awakening Anti-Demon factors and mastering them were women. As a result, male Anti-Demon Ninjas were extremely rare within the organization, and powerful male Anti-Demon Ninjas were rarer still.
Although Yukito Mizuki could not technically be considered an Anti-Demon Ninja, he had nevertheless caught Teacher Uehara's attention.
The Uehara Family was not as desperate for heirs as the Mizuki Family, which had only Yukikaze as its legitimate successor, but it was not particularly prosperous either.
If Teacher Uehara had been born in an earlier era, she would have been pressured into marriage and childbearing long ago. Although no one pressured her now, her age occasionally led her to think about such matters.
The problem was that finding a suitable partner was not easy. Teacher Uehara had no intention of settling for just anyone.
Although Yukito was several years younger than her, his appearance, temperament, and strength all met her standards for a potential partner.
As for the age gap, Anti-Demon Ninjas generally lived much longer than ordinary people. As long as nothing unexpected happened, an age difference of less than ten years was hardly a problem.
