Anime Crossover: Loading entries, there are too many brother-complex sister characters.

What's more, this happened in front of so many powerful and influential people!

"The effects of the medicine are most likely real!"

Upon hearing the secretary's words, Kyoko Yuuki remained silent for a moment.

"I see."

She hung up the phone and stood there, lost in thought.

Any normal person can realize just how terrifying and valuable a drug that can restore youth, revive the bodily functions of the dying, and extend lifespan truly is.

no doubt.

When Lady Yukinoshita took out this miraculous potion to sell, the path to heaven had already been paved for the Yukinoshita Foundation!

Others might also think that the Yukinoshita Foundation might attract the attention of other powerful conglomerates because of its possession of a valuable asset.

However, Kyoko Yuuki, who knew of Kuzeha's existence, was well aware of the terrifying existence behind Lady Yukinoshita.

"The Yukinoshita Family Foundation must have been able to produce something like this because it was brought by Mr. Kuze..."

She originally thought that her decisions and actions were decisive enough.

Although not as radical as Lady Yukinoshita, she can at least catch the fast train of Kuzeha.

But unexpectedly, it wasn't a fast train, it was a rocket!

In a split second of hesitation, before she could even get on board, the Yukinoshita Group was about to take off!

She had intended to call Mrs. Yukinoshita to inquire about the information herself.

After thinking about it, he stopped moving again.

Where is Asuna?

She turned to look at the butler in the living room and asked.

"Madam, Miss Asuna is training at the kendo dojo with Lady Kanae and Lady Shinobu!"

Upon hearing this, Kyoko Yuuki headed straight for the kendo dojo.

Kendo dojo!

Shinobu Kocho and Asuna Yuuki have just finished a sparring match.

Shinobu Kocho leaned back on the wooden floor, her delicate yet spirited face flushed with the effects of vigorous exercise.

She looked at Asuna Yuuki in front of her, a hint of disbelief appearing in her purple eyes.

"Asuna, did you have an epiphany today? You've improved so much!"

In the past, their matches were always evenly matched!

And she won most of the time!

But today, she was completely outmatched by Asuna Yuuki!

Speed ​​was rapid and torrential!

His swordsmanship was impenetrable!

The pressure was so great that she could barely breathe.

Shinobu Kocho vaguely felt that this sense of oppression was even stronger than that of her older sister, Kanae Kocho.

Asuna Yuuki wiped the fine sweat from Shiro's forehead with a handkerchief, her heart filled with shock!

When she practiced with Kuze and Saeko Busujima at school, she felt that she was improving very quickly.

But after sparring with Shinobu Kocho, she truly realized how terrifyingly much her strength had improved thanks to Kuze Yu's one hour of special instruction!

"It's... Mr. Kuze's breathing technique, isn't it?"

Before Asuna Yuuki could speak, Kanae Kocho, who had noticed something amiss, spoke up with a hint of excitement.

Asuna Yuuki turned and glanced at her, then nodded emphatically.

"Mr. Kuze not only pointed out the shortcomings in my swordsmanship, but also helped me improve my breathing technique!"

Upon hearing this, the butterfly sisters' breathing became a little rapid.

Kuze once said that his breathing technique could double the strength of the Demon Slayer Corps members.

Having witnessed firsthand the strength of Kirigaya Suguha and Tsuyuri Kanao, they believed it to be 70% true!

Even if it doesn't double, it can at least boost the Demon Slayer Corps' strength by a significant margin.

Now, seeing the results that Asuna Yuuki displayed after only one day of training, they finally realized...

Kuze Yu's estimate of doubling is still too conservative!

"However, I promised Mr. Kuze that I would not pass on the breathing technique to outsiders."

Asuna Yuuki looked at the two women with regret.

The Butterfly Sisters shook their heads indifferently at this.

Kuseha had already informed them of the conditions.

However, since it involves the Demon Slayer Corps, they cannot make the decision.

“Master, I think Mr. Kuze is quite easy to talk to. You can give him another try!”

Asuna Yuuki spoke up, trying to spur him on.

The butterfly sisters exchanged a glance and fell into deep thought.

Just then, they saw Kyoko Yuuki walking over.

"Lady Yuki".

"Mother."

Kyoko Yuuki nodded to them, then looked at Asuna Yuuki and asked.

"Asuna, did you see Mr. Kuze at Soubu High School today?"

Yuuki Asuna nodded.

"After I joined the kendo club, Mr. Kuze gave me special instruction..."

The girl spoke seriously, but now, recalling her attire during the special instruction, a hint of shyness appeared in her beautiful eyes.

Upon hearing this, Kyoko Yuuki nodded her chin in satisfaction.

Judging from Kuzeha's attitude, at least he has no prejudice against the Yuuki family or Yuuki Asuna.

The Yuki family still has a good chance of boarding this rocket to the sky!

However, we can't take it slow anymore!

Kyoko then told them about the youth-restoring potion.

A moment of confusion appeared on the pretty faces of the three girls.

If they hadn't heard it from Kyoko Yuuki, they would have thought it was utterly absurd ramblings!

"If lifespan can really be extended, then perhaps the lord's body can hold on for a few more years..."

Kanae Butterfly thought of Kagaya Ubuyashiki, the lord of the Demon Slayer Corps.

In recent years, Kagaya Ubuyashiki has been plagued by illnesses, and his health has been deteriorating day by day, which is not optimistic.

The appearance of this medicine is actually a good thing for the Demon Slayer Corps.

"but……"

The butterfly sisters exchanged a glance, and a premonition suddenly arose in their hearts.

"Not only humans, but perhaps even demons... Muzan Kibutsuji would be interested in this potion!"

Thinking of this, Kanae Kocho turned to look at Kyoko Yuuki and said in a low voice.

"Lady Yuuki, we must inform the Yukinoshita family to be on high alert at night during this period, as they are very likely to be attacked by demons!"

Upon hearing this, Kyoko Yuuki nodded slowly.

He then sent a message to Mrs. Yukinoshita!

The potion that Lady Yukinoshita released at the banquet spread at an alarming rate among the elite circles of Japan and even the world.

For the powerful and wealthy, this was destined to be a sleepless night!

All living things are greedy and never satisfied!

Death is the end that all living things fear!

The more you gain and the more you possess, the more you fear death!

Now that a drug has appeared that can delay their death, how could they not go crazy!

Hero Association Headquarters.

In the conference room.

The projection flickered, and one after another, illusory figures appeared on the seats.

All six seats were occupied.

"Hehe, it seems the temptation of extending lifespan is quite strong, since they've all come today!"

The leader spoke, but the others remained silent.

A moment later, a unique girl's voice slowly rang out.

"After all, this is no small matter."

From the projection, one could vaguely discern that it was a beautiful silver-haired girl.

She is none other than the current head of the Hyakugaku clan, Kirari Momogaku.

As soon as Momobami Kirari finished speaking...

The others all turned to look at her.

One of the voices asked impatiently.

"Miss Momobami seems to be here too. That potion, just as advertised, can restore youth and extend lifespan?"

Upon hearing this, Kirari Momobami merely turned her head and glanced at the other person.

"Nao Hayasaka of the Shinomiya Group was also present. I think Mr. Shinomiya should know the most accurate facts."

Although Kirari Momobami did not respond, her words implied that she had affirmed the effectiveness of the medicine.

"The Yukinoshita Foundation... is truly remarkable..."

A sigh escaped, and everyone's gaze flickered slightly.

The destruction of the House of Evolution and the loss of Dr. Genus's remains caused them to miss out on the technology that could enable immortality.

But they didn't expect things to take such a turn for the better so quickly.

The Yukinoshita Foundation in Japan has released a weakened version of the drug.

"However, as a real estate conglomerate, the Yukinoshita Group is capable of producing something like this..."

A low murmur rose among the crowd.

They all shared the same doubt.

But this is not the time to think deeply.

Soon, the commander, Zekingel, who had been temporarily summoned, arrived at the conference room.

"Zejinger, if I remember correctly, didn't the Yukinoshita Foundation express its desire to join the Hero Association?"

He had barely arrived when Shinomiya Kōkō, the representative of the Shinomiya family, asked a question.

Zekingel was slightly taken aback, then thought back for a moment.

"That's right!"

He nodded.

"Lady Yukinoshita has inquired about this matter, and we have provided them with the various evaluation criteria required for the application, but they haven't handed them over to us yet!"

Upon hearing Zejinger's words, the eyes of everyone above lit up.
