If word got out that becoming Eirin Yagokoro's test subject for a single, comprehensive physical examination would net you a perfectly tailored growth plan from her…
Well!
The doorstep of Eientei, even if reinforced with the power of Eternity and the moment, would be utterly worn away by the endless stream of seekers.
"Here, take this potion."
Eirin handed Kira a vial of emerald-green liquid. "Drink this. It will restore your body to its most perfect state. Only then will the examination be meaningful. The bath is over there. There's a prepared bathrobe inside. You may go and wash up first."
"Alright."
Having already agreed, Kira saw no reason to hesitate. He took the potion and downed it in one gulp, then headed for the bathroom.
"Eirin, you are not to harm Father," Kaguya said with utmost seriousness the moment Kira was gone.
"Your Highness, I have no intention of harming Kira," Eirin replied calmly. "He is simply… too unique. I need to conduct an in-depth examination. Otherwise, with his innate abilities, his current efforts are nothing but waste."
"All his hard work over the years… much of it has been wasted. It looks like diligence, but in reality, he's squandering his real potential."
"Good." Kaguya let out a soft sigh of relief and gave a slight nod. She trusted that Eirin wouldn't lie to her.
Besides. Eirin wasn't wrong. Kira's growth, facilitated by his aunt, had been purely through unorthodox methods. Much of his effort, while not entirely useless, had failed to achieve maximum efficiency.
His current progress, according to Eirin's calculations, could have been attained in just two years with proper guidance.
Of course.
Exactly how much hardship he would have had to endure in those two years? Well, that was another matter entirely!
Well... Cramming fifteen years of progress into two years? Suffering was a given, wasn't it?
"Please rest easy," Eirin said as she estimated the time. She made her way towards the examination room.
...
In the examination room, Kira had finished his bath and changed into a white sleeping robe. He was drying his hair as he stepped out, only to find Eirin already seated in a large executive chair.
She had even changed into a pink nurse's uniform. Her long, slender legs were sheathed in white stockings, and she wore white high heels—the picture of a perfect nurse.
It's just for some reason... it felt lewd.
"What's this all about?" Kira wasn't the type to lose his head at the sight of a pretty woman.
Besides, it wasn't as if he'd never been with a woman before. He just found Eirin's getup rather strange. And where had she even gotten that chair and outfit?
And also…
It was only now that Kira took a proper look at the room's equipment. This machinery… Just how advanced was the technology of the Lunar Capital? This was ridiculous.
"This attire will help stimulate you, allowing me to gather more accurate data for my examination. Let us begin." Eirin's voice was cool and detached, but combined with the outfit and the setting…
Well.
It was definitely stimulating, alright.
Kira didn't question it further. Following Eirin's instructions, he lay flat on the room's only surgical bed.
Hmmm…
He had to admit, lying on a surgical bed with Eirin standing beside him… it did make him feel a little nervous.
What followed was a thoroughness Kira had never experienced before. He was like a doll, manipulated according to Eirin's every direction as she conducted the examination. From head to toe, she checked everything with painstaking detail.
In his previous life, he'd had full-body checkups before. But compared to Eirin's examination? Those were like a child's play.
The entire process lasted nearly three hours before it was finally 99% complete. Why 99%? Because one final item remained.
"So…" Kira, feeling more bewildered than embarrassed, sat on the edge of the surgical bed, supporting himself with his hands. "Eirin, this… how exactly am I supposed to… check this?"
That's right.
They had come to the last piece, the most intimate—and perhaps the only truly private—part of a man's body.
But how in the world were they supposed to manage this?
Was he supposed to… use his own hands? Hell no. He wasn't using his left hand anymore. He wasn't going down that damn road again.
So maybe…
Should he call Saeko over and have a fiery night right in front of Eiriri?
"..."
Either option seemed utterly, profoundly absurd.
"One moment." Eirin was busy making detailed records—so detailed it was mind-boggling. She'd even documented his emotional state at various points.
She seemed to have categorized human emotions into countless types, each correlated with specific physiological data from the examination.
Only someone of Eirin's caliber could perform such an exam. Anyone else, Kira estimated, would need at least a month or two to complete something this exhaustive.
"Done. I will collect the final sample myself." Eirin set down her clipboard, turned, and walked towards Kira, her white-stockinged legs crossing elegantly with each step in her high heels.
"…Huh?" The rhythmic click of her heels on the floor made Kira's mind go numb. What was happening now?
Especially when…
Eirin approached with complete naturalness, and began to tie up her hair.

Another hour later, Kira emerged from the examination room, now dressed in his long gown. His steps were slightly unsteady—not from physical weakness, but because his spirit hadn't quite recovered from the shock.
"Father." Houraisan Kaguya was sitting in Eientei's rear garden, sipping tea. She smiled as she greeted him.
"Kaguya." Kira sat down beside her, picked up a teacup (not caring whose it was), and drained it in one go. Only then did he slowly begin to feel like himself again.
"Hehehe~" Watching her father's state, Kaguya could easily guess what had probably happened. She couldn't help but cover her mouth with her sleeve, laughing softly.
Kira shook his head, a complex sigh in his voice. "Eirin, she's really something else…"
"Father, how were Eirin's… techniques?"
"I've heard that this was Eirin's first time attempting this."
"After all," Kaguya continued, looking at Kira with open curiosity, "aside from someone as special as you, Father, no one else would ever catch Eirin's interest."
"…"
Kira listened to his daughter's words. After a moment of silent contemplation, he ultimately said nothing. He simply raised his hand and gave a firm, silent thumbs-up.
Eirin was really professional. With a calm face, she used her hands, feet, mouth, and thighs with great synchronicity. And in just an hour, she had drained Kira completely.
