The next afternoon, after completing the discharge procedures at the front desk, Kamiyā Yuu returned home with his sister Kamiyā Sora, who had taken leave from school.
It was a 2LDK apartment—both familiar and unfamiliar from his memories.
In Japan, "2LDK" roughly corresponds to a three-room, one-living-room layout. The "2" referred to rooms excluding the bathroom and living room—typically bedrooms. "L" stood for living room, "D" for dining room, and "K" for kitchen. Being able to afford such a place was thanks to the sizable compensation from the accident. Most ordinary working families in this world live in cramped 1DK units, with only slightly wealthier households having larger layouts.
"Click—"
Unlocking the door, the first thing he saw was the low entryway. Beside it, a shoe rack neatly displayed several rows of shoes—most of them were Sora's various styles of girls' leather shoes, followed by indoor slippers.
There were only two pairs of indoor slippers.
Which meant—
Almost no guests had ever visited this quiet home.
"Phew~!"
Sora quickly slipped past him and sat down in the entryway, letting out a soft breath. A faint sheen of sweat dampened her silver bangs. Her body was more delicate than that of ordinary girls, and the walk from the hospital had already exhausted her.
"I'm home."
Even though the house was empty, Kamiyā Yuu still muttered the words out of habit.
"Tired…"
"Yuu, help me take them off."
Sora lay back in the entryway, her posture rather unrefined for a girl. She slightly raised her foot, signaling him to remove her black, round-toe leather boots.
Kamiyā Yuu smiled helplessly, crouching down to gently take them off.
"I'm the one who just got discharged from the hospital, you know."
The boots were simple in design and came off easily. Supporting her slender ankle, he took a pair of black rabbit-themed slippers from the rack and put them on her.
"This level of activity would be easy even for a seriously ill patient. And since you've recovered, you should properly fulfill your duties as an older brother."
Sora yawned lazily, looking like she might fall asleep right there.
"An older brother doesn't have the obligation to put shoes on his little sister."
"No. An older brother is the slave of his little sister. Since ancient times, hasn't helping the master put on shoes been a slave's duty?"
Her cool voice carried a faint hint of coquettishness as she turned over, resting her head on her arm and slowly closing her eyes.
—You win. I'm a siscon.
Kamiyā Yuu chuckled inwardly. This level of "servitude" was something he didn't mind at all.
"Sora, if you sleep here, you'll catch a cold. Especially with your weak constitution. I don't like the smell of hospital disinfectant."
Sitting in the entryway and changing into slippers, he frowned at her already sleeping figure.
"Mm… I don't want to either… just a little longer…"
She murmured. The back-and-forth between school and hospital had clearly taken its toll.
"Ah~!"
Kamiyā Yuu lay down beside her, facing her delicate, flawless profile. No matter the angle, he couldn't find a single imperfection. Her beauty made simple words like "pretty" or "cute" feel pale and inadequate.
With her eyes closed, she looked like a sleeping princess from a fairy tale, breathing softly.
He reached out, gently brushing aside her silver hair.
"You've worked hard these past few days."
There was no response.
Carefully, he picked her up and carried her to the living room, placing her on the sofa and covering her with a light blanket.
But when he opened the bathroom door, he was greeted with quite a sight—
A large laundry basket stuffed full of clothes Sora had changed out of over the past few days. Light white underwear, simple Gothic dresses, and even the sailor uniform she wore yesterday were all mixed.
Holding the basket with one hand, Kamiyā Yuu sighed, rubbing his forehead.
"Right… she still doesn't know how to use a washing machine. Even though she's perfectly fine with something as complicated as a computer."
Separating the clothes and underwear, he filled the bathtub with warm water before going back to wake Sora.
"Go take a bath first. Sleeping like this without washing won't be comfortable."
"Mm…"
Still half-asleep, Sora slowly got up and walked toward the bathroom, rubbing her eyes.
...
After settling Sora back into her room, Kamiyā Yuu finished cleaning up the mess she had left over the past few days.
Even he was surprised at how skilled he was.
Back when he was Su Yang, he had been extremely lazy—aside from necessities, most household chores were left to his mother.
"Clothes and underwear washed separately… they should be dry by tonight. Expired food in the fridge—thrown out. Dirty dishes—cleaned. What else…"
After spending most of the afternoon tidying up, he finally returned to his own room.
It was a simply decorated bedroom. Aside from basic furniture, there was a desk in the corner covered with scattered sheets of paper, along with various drawing tools neatly arranged in a pen holder.
These were essential tools for a key animator—used for practicing drawing skills.
But Kamiyā Yuu wasn't particularly interested in them right now.
Instead, his attention shifted to the bulky black laptop on the desk.
"As expected, technology in this world is quite behind. I remember this laptop cost me nearly a year's savings, yet it doesn't even have an SSD."
Sitting down, he plugged it in and powered it on. A password screen appeared.
"The password should be Sora's birthday… Whether as Su Yang or Kamiyā Yuu, I'm seriously a siscon."
Having just transmigrated, and with many of Kamiyā Yuu's memories still unclear, he didn't yet fully understand this world.
If transmigration were possible—
Who could say there weren't superpowers? Aliens? Or even supernatural beings?
"Let's check if there's anything about supernatural powers. The internet should at least have some clues. If they exist, I'll try to develop in that direction."
He typed keywords related to supernatural abilities into the search engine, carefully combing through every piece of information.
After an hour, he gave up and concluded:
"Information about supernatural powers is just like my previous world—mostly rumors and speculation, nothing reliable. Either this world has extremely tight secrecy… or such things simply don't exist."
"Either way, it doesn't affect my current plans much."
"Next…"
Kamiyā Yuu's eyes sharpened.
He clearly remembered the consciousness space from last night. With that ability acting as a bridge between the two worlds' information—
He could use it to gain advantages.
Songs, novels, anime, technology, inventions—
Everything from his previous world was now within his reach.
