Kaguya-sama: Love Is War wants me to turn myself in.

As for their objectives...

"Rhombus-shaped Hospital".

Kaguya Shinomiya crossed her arms and whispered:

"This abandoned hospital leads directly to an underground cave, which is obviously inextricably linked to Hiruko-gami. The mountain path we just went down was not naturally formed; there are traces of artificial excavation everywhere. It couldn't have been secretly carved out by one person."

Hayasaka Ai continued her analysis, saying:

"According to the information brought back by the senior from last week, the replacement of humans by shadows is not a random act, but has a clear goal. Therefore, it is reasonable to judge that the director and senior management of the diamond-shaped hospital have most likely been replaced by shadows. After all, only with the director's support and consent can the mountain road be dug out legitimately."

Yukino Nekoshita whispered:

“The diamond-shaped hospital has been abandoned for decades. In other words, the shadows working in the hospital now have been around for decades and know more information than newly created shadows. They may even know the true identity of the Four Hands.”

Amamiya Natsuki raised her right hand and said softly:

"You've already said everything, what am I supposed to say?"

Fujiwara Chika looked up at her and said in a clear voice:

"At times like this, the chairman should naturally say something to boost morale."

The other girls also looked over when they heard this.

“Let me think…” Natsuki Amamiya pondered for a moment, then said, “Let’s clear the dungeon, and then everyone can participate in the real summer festival together.”

"..."

Once the skills were applied, everyone immediately got to work.

Twenty minutes later.

Amamiya Natsuki and her companions stopped in front of a three-story hospital.

"Rhombus Hospital...we've arrived."

The island is not large, with a permanent population of only a thousand. Therefore, there is only one general hospital on the island. After Natsuki Amamiya and her companions disguised themselves as ordinary tourists, they simply asked a passerby and learned the exact location of the hospital.

"The transformation time is running out," Natsuki Amamiya whispered. "Let's find a place to wait, and go to the hospital after we've finished applying the skill."

Chika nodded in agreement:

"Let's go to that KTV up ahead, get a private room, and take a look at the information that Haimeng and the others just gathered."

"can."

The group went to a nearby karaoke bar, entered a private room, deactivated their transformations, and then took out their phones to check the information that Hai Meng and the three senior students had collected.

Fujiwara Chika softly recited:

"According to the elders on the island, the deity worshipped on Ridu Island in the past was not Hiruko-no-Kami, but Inari-no-Okami. Later, during a great famine three hundred years ago, Hiruko-no-Kami appeared and helped people survive the famine, thus becoming the object of worship for the island's inhabitants..."

Amamiya Natsuki said:

"Three hundred years ago... that must have been the Kyoho Famine during the Edo period."

Kaguya Shinomiya said softly:

"According to the information gathered by my senior, the Rhombus Hospital, as the only hospital on the island, also has a history and heritage spanning hundreds of years, which coincides with the time when Hiruko appeared."

Hayasaka Ai took a sip of her chilled drink and sighed softly, "So, we definitely came to the right place."

Yukino Yukinoshita raised her right hand, her slender fingers tucking a strand of hair that had fallen across her chest behind her ear, and whispered:

"My sister sent me a message. There's a long-standing legend on the island about the Shadow Disease. It's said that some people will see a shadow that looks exactly like themselves. After a few days, the shadow will kill the human and then take over the identity to continue living."

Amamiya Natsuki sat on the sofa, holding Hayasaka's hand with her left and Chika's hand with her right, and was applying skills when she heard this:

"In other words, the fact that Hiruko-gami eats people is not a recent phenomenon, but rather began hundreds of years ago."

Kaguya Shinomiya pursed her pink lips and pondered:

"Hospitals are the most normal places for birth, aging, illness and death, which is why someone built a hospital specifically to provide food for Hiruko-gami."

While toying with the spy maid's fingers, Amamiya Natsuki said:

"To put it simply, during the great famine three hundred years ago, Hiruko came to Hito Island and then, for some reason, formed a bond with the Hishigata family. For example, Hiruko's first copying target was a member of the Hishigata family. Of course, there are other possibilities. Later, the Hishigata family founded the Hishigata Hospital to provide food for Hiruko... As long as you go to the library or archives and find out the time of the famine and the founding time of the Hishigata Hospital, you can confirm the relationship."

"However, nothing in the world stays hidden forever."

"There are only so many residents on the island. Someone discovered the existence of shadows, and thus the legend of the shadow disease began to circulate."

Fujiwara Chika asked in confusion:

"Strange, knowing there are man-eating monsters on the island, why don't the residents run away?"

Kaguya Shinomiya said softly:

"Because the Hiruko God's 'appetite' was probably not very large in the past... illness, natural aging, accidental death, etc., the natural metabolism of the population could satisfy the Hiruko God's food needs, so the island's residents did not flee in fear."

If Hiruko-shin were like the three demon kings of Lion Camel Ridge, devouring a hundred or so people every year, the island would have been deserted long ago.

Amamiya Natsuki nodded and said:

"Hiruko-no-Kami is eating a lot today because he is injured and needs to replenish a lot of energy."

Hayasaka Ai tilted her head and said:

"Why would such a powerful Hiruko-gami be injured?"

“It must be related to the sudden abandonment of the old hospital.” Yukino Yukinoshita looked at her phone and said softly, “My sister just sent me a message saying that decades ago, the island was bombed by air, and part of the Diamond Hospital collapsed in the bombing. It was for this reason that the Diamond Hospital was relocated and rebuilt.”

"Huh?" Fujiwara Chika's eyes widened. "An air raid decades ago, could it be... Ah!"

Amamiya Natsuki pinched Chika's waist and said seriously:

"There are some things that cannot be said."

Fujiwara Chika covered her mouth with both hands: "I won't say anything more."

These stories were pieced together based on the information gathered, rather than being wild guesses, and were highly reliable. So, at Natsuki Amamiya's suggestion, the girls wrote them down in their notebooks and saved them in their game inventory, just in case.

After a while.

"The pasting is complete." Amamiya Natsuki stood up and said, "Everyone, go find your transformation targets."

Hayasaka Ai reminded him:

"There are security cameras in the hallway, so please remember to wear hats."

"know."

Amamiya Natsuki picked up a baseball cap, put it on her head, and then stepped out of the private room.

Mystique's ability to transform requires touching someone's body to copy information; she can't simply transform into whatever she wants, so she needs to find a target first.

Natsuki Amamiya walked to the end of the corridor, turned and entered the restroom, where she happened to see a young man washing his hands at the sink, so she went over and gave him a brief greeting:

"You are the one."

He had previously transformed into a girl at Zhu Zhu and Shoko's school. To be honest, there isn't much difference between boys and girls, but given the choice, Amamiya Natsuki would naturally prefer to become a boy.

Kaguya and Chika are the same; they only want to transform into girls.

Finished washing.

Amamiya Natsuki pulled her baseball cap down and walked out of the restroom. She saw the man she had just copied standing at the entrance of the women's restroom, holding hands with a young woman. They seemed to be a couple.

Not long after, another woman came out of the restroom. She looked similar to the first woman and they seemed to be twins. The man reached out his other hand and took the hand of the girl who had just come out. The three of them left the KTV together.

"Oh, man..."

Amamiya Natsuki wanted to complain, but then she thought that she had no right to complain about others, so she turned her gaze away and went back to the private room to wait.

After a while.

Several girls returned one after another.

"Is everything alright?"

"Okay."

"Then prepare for action."

Amamiya Natsuki put away her phone, activated her transformation skill, and with a flash of light, she transformed into the young man she had just met in the restroom. Several girls also used their transformation skills to change into other forms.

"Ok?"

"Eh?"

Several soft gasps rang out in the private room.

The first sound came from Natsuki Amamiya. He was surprised to find that Kaguya and Yukino's transformed appearances were clearly those of the twin sisters who had been hugging the man's arm together in the corridor just now.

The second soft exclamation came from Fujiwara Chika, who exclaimed in surprise:

"What a coincidence, Kaguya-chan and Yukino-chan have transformed into the same person."

“It’s not the same person.” Hayasaka Ai observed carefully, then shook her head and said, “They just look very similar.”

Natsuki Amamiya said:

"They should be twins, but we don't know who is the older sister and who is the younger sister."

Kaguya Shinomiya and Yukino exchanged a glance, their feelings slightly complicated as they looked at each other with similar appearances. But that was all. They had even seen identical yandere young ladies before. They were just twins who looked alike, nothing special.

“It must have been an accident. I just chose my target in front of the vending machine.” Kaguya Shinomiya crossed her arms and said softly, “She was alone at the time. I didn’t expect it to be her sister.”

Yukinoshita Yukino said calmly:

"I chose my transformation target in the bathroom... as long as it doesn't hinder my movements, it's fine."

Hayasaka looked over curiously and asked:

"Senior, why did you look so surprised just now?"

After thinking for a moment, Amamiya Natsuki realized there was nothing she couldn't say, so she recounted what she had seen in the corridor.

"I see, so you're a couple who're dating as a trio." Hayasaka Ai smiled happily, putting her hands behind her back. "Does Senpai want Kaguya-chan and Yukino-chan to each hold one of your arms?"

"stare--"

The young lady turned her head and looked over.

Amamiya Natsuki said seriously:

"I never even thought about it."
