Training...

His cursed energy reserves had grown to a large extent that even his parents were astonished.

With his six eyes and an immense amount of cursed energy, he could practice incessantly without experiencing any depletion.

After only three months of practice, he more or less understood the true meaning of each word of incantation.

So, Kazuhiko moved on to applying incantation and methods he learned in his previous life to the barrier techniques. 

He tried basic curtains with different incantations with the same underlying meaning to test the effect.

"Arise from shadows, darker than night, A force of darkness, ready to ignite impure."

"With eyes that pierce, like a moonless sky, A presence so chilling, it makes demons cry."

"Cleanse the impure with even more impure might, A spirit of the underworld, shining so bright."

"In a world consumed by sin and despair, This avenger emerges, with a solemn stare."

"Unyielding and relentless, in pursuit of truth, Unleashing power, like a tempest uncouth."

"With every strike, evil trembles and quakes, As the impure are purged, their souls at stake."

...

After five months of training, Kazuhiko developed the ability to temporarily modify the barriers around his house.

He would weaken the barriers when his parents were not home, allowing him to use his divine dogs to hunt curses without breaking his promise to his parents.

He also created his first talisman after continuous practice.

The incantation he used to create the talisman was: "They emerged from the depths in search of their origin. I offer them the way back to their beginnings, allowing them to find solace in the darkness and set them free... RELEASE!"

This incantation allowed Kazuhiko to turn weaker curses into pure negative energy and seal them into the talisman.

The first time he created this talisman, he showed it off to his mother, hoping to impress her.

However, she responded by saying, "H-haha... I-it's nothing to be proud of, there are a lot of talisman experts in Jujutsu High... T-they can do even better work..."

Kazuhiko felt hurt upon discovering that his talisman was not as special as he had thought, but this motivated him to push himself further and prove his worth to his parents.

He quickly mastered the new incantation techniques he had created, and the fact that there were so many talented people in the field only fueled his excitement.

He felt a sense of exhilaration he hadn't experienced in a long time - the feeling of becoming stronger, of learning something new, of starting from scratch, and of wanting to showcase his abilities to others.

Most of the incantations he had known in his previous life were deemed useless, with only a few remaining that had entirely different applications than he had previously imagined.

For example, "Emerging from the depths of darkness, A powerful force, ready to harness. Eyes piercing through the blackest sky, A chilling presence that makes demons cry." - a devil summoning ritual he had occasionally used in his past life.

But when he applied it to his barrier, the third-grade curse that was trapped inside of it went insane and killed itself once a certain amount of time passed.

Even though it was hard to track the uses of every incantation, it was pretty interesting for him once he started to grasp their true essence. 

He recited an incantation: "No compassion bestowed, no leniency displayed, This solitary protector remains unswayed. Amidst the gloomiest trails, it ventures, A guiding light amidst the encroaching shadows."

With this, he successfully improved the use of the talisman he created that could seal pure negative energy.

His new talisman could perfectly seal pure negative emotions with traces of his own negative emotions.

This would emit the presence of high-level curses and keep lower-level curses at bay.

Additionally, by slightly releasing the sealing, it would attract all curses within a 300-meter radius, regardless of their grade. 

When his mother saw the new improvised talisman, she freaked out and snatched it from his hands.

"Kazuhiko! Why did you make something like this?! It's way too dangerous... How did you make it?"

Instead of receiving praise, he was severely scolded. He tried to explain the process of making it and its uses only to backfire.

"Huh?! Did you integrate traces of your own negative emotions into it?! What kind of negative emotion does a kid like you have to form such a dreadful talisman?"

Thankfully Kazuhiko fended it off with some random bullshit.

After that talisman was snatched away by his mother, he secretly made several talismans of the same type and hid them in his room but they were also snatched away once his mother found them.

After a month of persuasion, his mother finally gave in and decided to allow him and practice more about talismans seeing his passionate eyes. 

Once the six months passed since the start of his training, Kazuhiko's mother learned that she was pregnant.

Kazuhiko was going to have a little brother or sister.

Their family going to have another person.

"Oh, Kazuhiko, you lucky guy! You are going to have a sibling you always wanted...", his father said.

Only at that moment, he remembered the joke his father said six months ago.

'It wasn't a joke! Oyaji was serious at that moment!'

He and his father were abuzz at the announcement.

"What will we name the baby if it's a boy?"

"What will we name it if it's a girl?"

"We still have rooms, right? Oh, we can use Kazuhiko's old clothes and hand-me-downs."

There was no end to the topics to be discussed.

In the first month, there was a shift in his mother's food cravings, along with nausea, vomiting, and a general sense of fatigue- in other words, symptoms of classic morning sickness.

Kazuhiko temporarily put a hold on his practice and stuck to his mother, so he could take care of his mother's needs.

On one particular day, his mother revealed the answer to one of the biggest questions Kazuhiko had for a long time.

'Binding Vows'
