Save Your Life Three Thousand

Late at night, Hiruma tiptoed out of the old man's room, skillfully climbed onto the roof, and lay there leisurely watching the stars.

Suddenly, one end of a ladder was propped against the roof, followed by the sound of footsteps on wood.

With a series of creaks, Shinobu Kocho's little head popped up from below the eaves as he looked up.

"Shinobu, what are you doing?"

"Watching the stars!"

As he spoke, Hiruma pointed downward. Shinobu looked, nearly falling off in fright because it was so high.

"Ahhh!"

Just as she was about to fall, Hiruma grabbed her hand and pulled her up.

"At such a young age, all you know is how to take advantage of girls. You pervert!"

A little angel Hiruma appeared, pointing at Hiruma and scolding him.

The next second, a little devil Hiruma kicked the angel away and said smugly,

"Idiot, what are you talking about? I was only saving someone. How could I possibly have any ulterior motives?"

"Hiruma!"

"You're such a pervert! You grabbed a girl's hand and won't let go!" Shinobu gave Hiruma a sharp knock on the head and said indignantly, looking exactly like an angry little hamster.

"I was afraid you'd fall!" Hiruma hurriedly released her hand and guiltily looked aside.

And so, there was another little girl on the roof of the Kuwajima residence.

After lying there for a while, Hiruma took a small glass bottle filled with red liquid from his clothes. The bottle was shaped like a miniature chibi Hiruma.

He stuffed the bottle into Shinobu's hands, leaving her somewhat puzzled.

"What is this?"

"Save Your Life Three Thousand!"

"What?"

Little question marks seemed to float over Shinobu's head. Big eyes, big confusion.

"Take a swig when you're injured, and it'll speed up your wound healing. It's a treasured medicine passed down through my family!"

"Of course, it also works when you're sick. It lasts for one month!"

Listening to Hiruma's explanation, curious little Shinobu immediately exposed his lie and said seriously,

"But Grandpa Kuwajima said he found you. How could you have a family heirloom medicine?"

Hiruma: "Uh! (?_? )"

The old man really told her everything.

And were little girls these days all this hard to fool?

Its formal name was Save Your Life Three Thousand. Its common name was Hiruma's blood.

He feared people might find it hard to accept if he said it outright, so he had simply given it that name.

It was bloody, truly bloody, but it really could save lives. Jigoro Kuwajima could vouch for that.

"Come on!"

"Just keep it and use it. We're practically family. It's not like I'd poison you."

Shinobu pulled out the stopper, brought it close to her nose, and carefully sniffed it.

There was a faint rusty smell. This was blood.

"Your blood?"

"Mm!"

"My constitution is special. I eat a lot, and my blood has unusual effects too!"

"If you find it disgusting, then forget it. After all, asking you to drink my blood does sound a little strange."

Hiruma spoke calmly. After all, only demons drank blood and ate flesh. Normal people would find it difficult to accept.

"Then thank you. It really could save my life at a critical moment!"

"You really are kind of like a demon!"

Shinobu gladly accepted it. She had long noticed Hiruma's unusual traits; it was the instinctive reaction of a physician.

During that battle with Bakotsu, she had personally seen his wound scab over in less than a minute. That was simply not something a normal person could do.

"If you run out, just ask me for more!" Seeing Shinobu accept it, Hiruma smiled happily.

"This glass bottle is so cute. It even has an expression!" Shinobu held the chibi Hiruma in her palms and smiled, revealing a pair of shallow dimples.

As soon as she finished speaking, eight small glass bottles appeared between Hiruma's fingers.

Grinning, sobbing, fuming...

There were little bottles with all sorts of expressions, all thanks to the glassblower uncle in Mount Peach Town.

"I've got loads of these!"

Before Shinobu could reply, Jigoro Kuwajima's furious cursing rang out.

"You little brat, climbing onto the roof again!"

"Not sleeping in the middle of the night? You trying to fly to the heavens?"

Sigh!

Hiruma shook his head and said, "Shinobu, go to sleep. Otherwise, I'm going to get beaten up. You have no idea, the old man uses techniques when he hits me."

And so, Shinobu lived with this master-disciple pair, who were like bitter enemies, for a week.

One week later, the two bid farewell to Kuwajima Jigoro.

Their next stop was the Demon Slayer Corps Headquarters. As for Breathing Styles, Tendo Hiruma had a grand ambition.

Since the five major Breathing Styles had originated from Sun Breathing, the Original Breathing Style, he believed that by observing those five Breathing Styles, he could accomplish one thing with his talent—

Reverse-engineer them.

Demon Slayer Corps Headquarters.

A carefree teenage boy dressed in a black kimono stood at the headquarters entrance. He wore a bright, sunny smile, and merely standing there, he seemed like a little sun.

The boy had long yellow hair, its tips blazing fiery red. Beneath his thick black sword-like brows were a pair of bright, spirited eyes.

Beyond that blazing warmth, there was also a touch of gentleness in his features.

"Why hasn't the person Father mentioned arrived yet?"

Kyojuro Rengoku muttered to himself. Ever since his father returned, he had constantly mentioned a boy named Tendo Hiruma.

Kyojuro himself had developed a keen interest in this person he had never met, especially since the medicine he gave had actually stabilized his mother's condition.

It could be said that Kyojuro had nearly come to regard Hiruma as his own brother.

As the fiery elder brother waited anxiously, two small figures appeared on the horizon.

They were Hiruma and Shinobu.

"Wow, the headquarters really is well hidden. Without a Kasugai Crow, we definitely would've gotten lost."

Shinobu looked into the distance, unable to suppress the delight on her face because she could finally see her sister.

Hiruma was not as excited as Shinobu, since he knew far too much already.

But there was one thing he particularly liked: the scenery at headquarters was truly beautiful.

Kyojuro stared unblinkingly into the distance. At that moment, his mind was loading Hiruma's image.

Dark red hair, golden eyes, and a girl by his side.

Identity confirmed. He was the brother from different parents whom I acknowledged.

"Hiruma!"

"Please accept my bow. Thank you for saving my mother!"

With an expression of utter shock, Hiruma watched helplessly as his big brother dropped to his knees and slid right before him.

"Holy crap! ((???|||))"

"Big Brother, if you do this, I'll lose years off my life!"

"Hmm?"

"Big Brother?"

Kyojuro stood up, brushed the dust from himself, casually wrapped an arm around Hiruma's shoulders, laughed three times, and said,

"Since Brother Hiruma acknowledges me as his big brother, then let's become sworn brothers!"

Things were moving too fast. Hiruma's brain had already crashed.

He knew his big brother was fiery and enthusiastic, but he had not expected the temperature to be this high. At their first meeting, he was already trying to become sworn brothers.

"Stop, stop, stop!"

"This is our first time meeting."

"Yes, yes, yes!" Kyojuro nodded.

"Do you even know who I am?"

"You're Hiruma!"

"I don't even know who you are." If he had not known the plot, Hiruma really would not have known.

"I am Kyojuro Rengoku, twelve years old. My father is Rengoku Shinjuro, and my mother is Rengoku..."

Big Brother was an honest kid. His sincere gaze shone brilliantly, like a living Buddha.

"Can we become sworn brothers now?"

Hiruma was still dazed. What was this, The Story of How I Reincarnated in Another World and My Big Brother Insisted on Becoming Sworn Brothers with Me?
