"So, Kisaragi, don't you think the Ability of immortality is a bit too common?"
Haibara Ai thought for a moment and said, "Regarding the Paradise, the Black Organization kept it a secret from me before. Before I knew about the Paradise, I would have been certain that immortality was the Black Organization's goal for us to research medicine.
But now the Paradise is right in front of us. The Demon Blood that Saeko Busujima is currently using is already enough for immortality. So... is there still a need for the Black Organization to research such a common, undignified immortality Ability?
Considering this, I began to try to continue researching APTX4869 through the Workshop."
Saying this, Haibara Ai took out a sea turtle and displayed it in front of Kisaragi Rin.
"Please look."
Haibara Ai activated the Workshop, and a capsule transformed into microparticles, integrating into the sea turtle's body.
After about two or three seconds, the sea turtle's body suddenly emitted intense steam.
"This is... growing larger?"
Kisaragi Rin's Transparent World had already penetrated the steam, seeing every detail within the sea turtle's body.
He had thought the sea turtle would shrink like Haibara Ai, but it was actually growing larger?
In just two or three seconds, it expanded from its original basin size to that of a tire.
Then, with a "rip," this sea turtle, which had grown fangs and sharp claws, exploded!
Letting the Paradise absorb the shattered remains, Haibara Ai folded her arms across her chest and said seriously, "As you can see, this medicine has other potentials.
The APTX4869 that the Black Organization gave me to research is incomplete, or rather, I was only responsible for a part of the true research.
The direction of immortality research they told me was probably only a part of the true goal or a synonym..."
Kisaragi Rin quipped, "You look just like an evil scientist, with your unchanging expression."
"Doesn't that suit you perfectly? Master of the evil organization's Workshop, exploiting child labor."
Haibara Ai retorted, snorting coldly as she continued to explain her research findings, "According to my speculation, compared to immortality, the research direction the Black Organization desires is closer to the term 'Eternal Imperishability.'"
"Immortality, eternity..."
Kisaragi Rin rubbed his chin, deciding to temporarily put aside the investigation of this matter.
If he had to busy himself with everything, wouldn't this Haibara Ai be raised for nothing?
Moreover, he had already sensed that a Non-Human Girl had suddenly been added to the extraterrestrial girl helper handbook.
This meant that Saeko Busujima had successfully obtained the Demon Blood.
"This time, it hasn't been seven days again, has it?"
The first thing Saeko Busujima did when she woke up and saw Kisaragi Rin was playfully joke.
"Of course not, it hasn't even been seven minutes."
Compared to before, Saeko Busujima hadn't grown any strange demon horns or vertical pupils. Her purple hair just seemed more ethereal, and a strand of silver highlight appeared on the hair near her temples.
She looked ethereal yet enchanting.
"Well, Haihara, since you've admitted to being child labor, remember to go to bed early." Kisaragi Rin glanced at the time, confirmed it was late, waved goodbye to Haibara Ai, and prepared to return to the apartment.
"..." Haibara Ai didn't want to respond, but Saeko Busujima, behind her, took her hand and said with a smile, "Mitsuri made Sakura Mochi, let's go to the apartment to taste it together."

Meanwhile, at the Hot Spring Pool.
Lily was playing catch with a few people, having found a ball from somewhere.
Medea participated intermittently, and it took her a while to smooth out the blush on her face amidst the steam.
Hmm... with the help of Magic, she had secretly watched the entire battle between Kisaragi Rin and Saeko Busujima.
"This is an exercise... that's right... an exercise, but it really looks so embarrassing!"
The scene she had just witnessed replayed involuntarily in her mind, just like that day when she woke up and saw Esdeath doing that to the Master.
Medea whimpered, slipped, and sank into the hot spring, only her eyes visible.
"Who's going first tonight?" Shizuka Marikawa asked Lily from the side, "Or will you go together?"
Tomorrow was the weekend, with plenty of time. Recalling Kisaragi Rin's capabilities, Shizuka Marikawa thought that all four together shouldn't be a problem.
"Together! I, I don't know!"
Lily shook her little head, tossed the ball to Kanroji Mitsuri, and then secretly observed Medea's expression.
With Medea and Esdeath present, it was impossible for her tonight.
Moreover, Lily wasn't really prepared.
In Fuyuki City, whether it was Medea, Esdeath, or Medusa, everyone had known Master for a similar amount of time, and their intimacy with Kisaragi Rin was basically on the same starting line.
In that atmosphere, Lily wouldn't consider other things, naturally wanting to join the competition to gain more affection.
But now, having come to the Main World and seeing these women who had already had relations with Kisaragi Rin... Lily scratched her face, suddenly no longer attaching so much importance to the matter of "who goes first."
Actions require a sense of accomplishment.
Given the current situation, even if she successfully pulled rank on Medea, most of the fun would be lost.
Besides... Lily recalled the size she saw that morning and unconsciously extended her hand, making a grasping motion in the air.
"Ugh... it's probably impossible, right...?"
With a tense waist, Lily also sank into the water.
"What's wrong with those two?"
Kanroji Mitsuri looked at Anna in her arms. Because Miss Anna, like Miyuri Asou, was only about 1.3 to 1.4 meters tall, it successfully aroused her maternal instincts.
"I don't know." Anna blinked, leaning against the soft cushion. She actually knew what Lily was thinking, but saying it out loud would be a bit embarrassing.
After all... even the legal loli Miyuri Asou isn't afraid, so what's there for you, Lily, to be afraid of?
Speaking of Miyuri Asou, she was pushing Mafuyu Kirisu, who was about to pass out from soaking.
"Miss Kirisu, are you done soaking?"
"...Done."
Mafuyu Kirisu responded groggily.
Then she realized what she was doing and quickly sat up straight, patting her face.
"They're all here, Kisaragi might come. If he sees me like this, the teacher's dignity will be completely lost." Thinking of such a scene, Mafuyu Kirisu quickly pulled up Miyuri Asou and said in a panic, "Thank you for the hospitality, I'm done soaking."
Just then, Kisaragi Rin happened to walk in.
And Mafuyu Kirisu, being too comfortable, hadn't realized that her Yukata sash had come undone.
