Soul Society, Seireitei.
The Miagawa family, a minor noble house, was located in the northernmost part of the Seireitei. Their residence was right next to the Ukitake family, who were also minor nobles.
For nearly a hundred years, their strength had been waning, and they relied on selling various novel items from the World of the Living as their primary means of livelihood.
At this moment, within the Miagawa family residence, a young man in a gray haori, his expression filled with excitement, dropped what he was doing and strode quickly toward the main gate.
"Three years! The time has finally come!"
The young man swiftly took a wooden plaque from behind the door and tucked it into his pocket.
"System, bring up the novice mission!"
"Ding! Novice Mission: Please proceed to Northern Rukongai, District 80 (Zaraki District) to check in on the day of the Soul Society's highest Reishi concentration!"
"Ding! The system has detected that at this moment, the Soul Society's Reishi concentration has reached the required threshold for check-in. The mission has been activated for you."
"Please proceed to Northern Rukongai, District 80, as soon as possible to check in. You will receive a system reward!"
Northern Rukongai, District 80, also known as Zaraki District, was the most dangerous area, farthest from the Seireitei and with the worst public order.
But at the same time, it would be the beginning of his rise!
Three years ago, Jin had transmigrated into the Soul Society and become the eldest son of the Miagawa family, Miagawa Jin.
Initially, when he learned he had crossed over into the world of Bleach, he was filled with excitement. After all, he found himself in the period before the main storyline began.
Kurosaki Ichigo had not yet appeared, and Aizen had not yet officially betrayed Soul Society.
He had enough time to prepare and get involved.
But soon after, his excitement faded.
Although he was a member of a minor noble family, he had almost no spiritual power in his body.
This meant he could never enter the Soul Reaper Academy, and thus could never become a Soul Reaper.
Although he had awakened a cheat called the "God-level Check-in System," it had remained silent for three years.
And today, he had finally reached this moment!
...
The Rukongai was the residential area for common souls, surrounding the Seireitei.
It was divided into four cardinal directions—East, South, West, and North—totaling 360 districts.
Within each direction of the Rukongai, District 1 had the best environment and excellent public order. District 80, on the other hand, was a barren wasteland where famine was rampant, and countless souls slaughtered each other for the right to survive.
The place Jin was heading to this time, Northern Rukongai's District 80, was an especially notorious place.
The current captain of the 11th Division, Kenpachi Zaraki, hailed from that very district.
Jin quickly made his way to the northern gate of the Seireitei. This gate was called the "Black Prism Gate" and was guarded by the hero "Danzōmaru."
Generally, souls were not allowed to enter or leave the Seireitei at will, but the Miagawa family was a noble house, after all, and naturally had certain privileges.
Relying on the wooden plaque that symbolized his noble status, Jin successfully passed through the gate and entered the Northern Rukongai.
Once inside, Jin didn't linger and pressed straight ahead.
Three years of noble life had made him very familiar with the geographical layout of the Soul Society.
The wilderness at the end of the Northern Rukongai was District 80.
As he advanced, the surrounding environment began to deteriorate.
After entering the area beyond District 65, there were even corpses scattered everywhere on the road.
Rōnin also began to rush out and attack Jin continuously.
However, since he had come here, he had of course prepared some life-saving measures in advance.
The gray garment he wore was called a "Spirit-severing Haori."
It was an item of clothing developed by the Research and Development Institute of the Thirteen Court Guard Squads, generally supplied to nobles with insufficient spiritual power.
Even someone with low spiritual power could gain a certain speed boost by wearing it.
All kinds of killing intent and sword pressure surged toward him. Although Jin was already panting heavily and had been slashed on his back, he did not stop. He gritted his teeth and continued to charge forward.
He knew that if he stopped here, what awaited him was certain death.
After an unknown amount of time, he finally burst into the territory of District 80.
"Ding! Congratulations, Host, for successfully arriving at the check-in location. Check-in officially beginning!"
"Check-in duration: 10 seconds. Exiting midway will be considered a failed check-in!"
Hearing the system's voice, Jin's heart leaped with joy.
But in an instant, he once again felt a terrifying killing intent rushing toward him.
The cold glint of a blade flashed.
The souls of Zaraki District were even more vicious.
To ensure he completed the check-in, Jin resolutely charged deeper.
The system's countdown began.
"Nine seconds."
"Eight seconds."
Jin's haori was already torn to shreds.
Several men holding broken blades rushed forward, their killing intent palpable.
One of them, his face contorted in a savage grin, shouted, "You filthy noble! Don't... look down on us!!"
Jin desperately dodged, but his body, devoid of spiritual power, was ultimately no match for these people with their stronger spiritual power. Multiple wounds had already appeared on his body.
"Three seconds."
"Two seconds."
"One second."
Jin was surrounded by several men, with no more room to dodge. Their eyes cold, they swung their blades without hesitation.
At this critical moment, the countdown ended.
"Zero."
"Ding! Congratulations, Host, check-in successful!"
"Mission Reward: Ultimate Spiritual Power and Devastating Spiritual Pressure!!"
