Chapter 3 — The Beginning of High School
Today was the day.
The day I finally entered high school.
More importantly…
The day I could unlock the Traveler Function.
I stood near the door of my house.
My mother looked at me with a warm smile.
"Take care, Hachiman."
My little sister waved happily.
"Goodbye, Onii-chan!"
Kamachi was always energetic.
I grabbed my bicycle.
"Yeah, yeah… see you later."
I left the house about an hour early.
Not because I was excited about school.
But because the system said the Traveler Function would unlock once I entered high school.
I wanted to see it immediately.
As I rode my bike down the road, something familiar happened.
A small dog suddenly ran into the street.
And from the corner of my eye—
A car.
Fast.
Ah… this scene again.
This was the exact moment that originally caused Hachiman Hikigaya to get hit by a car before enteringSobu High School.
But this time…
I was different.
I dropped my bicycle and sprinted forward.
In a flash—
I grabbed the dog and jumped out of the road.
The car sped past.
The dog barked happily and ran away.
I dusted off my uniform.
"No hospital visit today."
Without looking back, I picked up my bicycle and continued toward school.
Soon, the large school gate appeared in front of me.
Sobu High School.
So this is where the famous loner life begins.
I walked through the gate.
At that exact moment—
Ding.
Traveler Function Unlocked.
My eyes widened slightly.
Ding. Searching for available worlds…
Ding. Worlds Found.
Demon Slayer World
Jujutsu Kaisen World
I spoke in my mind.
"System… what does that mean?"
Ding. Host can travel to these two worlds.
Time Ratio:1 Month in another world = 1 Day in the host's original world.
That's… insanely useful.
"System, can I travel now?"
Ding. Does the host wish to begin travel?
I shook my head slightly.
"No. Not yet."
I still had questions.
"If I defeat Mahoraga, will I gain new abilities?"
Ding. Host can gain new abilities through:
• System missions• System shop (locked)• Personal training
"I see…"
"I'll need a technique strong enough to defeat Mahoraga in one hit."
Then another thought came to mind.
"How do I unlock new worlds?"
"And can I take other people with me?"
The system responded.
Ding. New worlds unlock after completing missions.
Ding. Host may eventually bring others or return with companions once higher system permissions are unlocked.
That made sense.
But one thing still bothered me.
"System… why don't you just give me the abilities directly?"
The answer came immediately.
Ding. It is for the host's benefit.
If the system grants an ability, it can also take it away.
If the host learns an ability himself, it can never be taken away.
I paused.
That actually made sense.
The system continued.
Ding. Bloodline abilities are different.
They require minor genetic modification, which the system can safely perform.
"Fair enough."
I sighed slightly.
"Then I'll have to learn everything myself."
Ding. Missions are available in other worlds.
"So if I want missions…"
"I have to travel."
My lips curved into a small smile.
"Well then."
"This high school life might not be so boring after all."
