Marrying Unohana Retsu from Bleach

As Araki opened his system, a line of data immediately appeared in his mind.

[Daily Routine Task: Entertaining one customer is complete, earning 1,000 experience points.]

[Daily Training Task: Perform 1,000 slashes is complete, earning 2,000 experience points.]

[Main Quest: Head to the Seireitei to join the Gotei 13.]

[Note: The rewards for the main quest depend on the rank of the position the host attains within the Gotei 13.]

Araki calmly looked at the task panel displayed in his mind.

Other than the newly issued main quest...

The two daily tasks that refreshed regularly on his system had already been successfully completed.

Without a ripple of emotion in his eyes, Araki skillfully used his thoughts to claim the rewards for the completed daily tasks. In an instant, the blue-glowing daily task panel in his mind turned gray.

"Character attribute template, open."

After successfully claiming the experience points, Araki immediately switched from the daily task template to his personal attribute panel.

Opening his character data panel, Araki stared at the long string of digits in his experience bar, falling into thought.

A ten-digit figure—ten billion experience points. No one but Araki himself could comprehend how many years it had taken to accumulate that much experience.

Without hesitation, Araki focused on the "+" symbol next to the Reiatsu Level section of his panel.

"System, level up."

The moment he issued the command, his vast pool of ten billion experience points instantly dropped to a mere 1,890. But in exchange, his Reiatsu level rose to Second Class.

Yes, the system's power upgrades brought him immense strength, but the experience cost was downright absurd.

Each level required ten times the experience needed for the previous one.

Since spending 10 experience points to unlock his Reiatsu and start at an innate Tenth-Class Reiatsu, Araki had poured over a billion points into advancing his Reiatsu to Third Class—essentially the captain-level standard by modern metrics.

It had taken him years of grinding, earning 3,000 points daily, to accumulate ten billion points, just to finally step into the Second-Class Reiatsu realm and trigger the system's main quest.

According to the standards of the original Gotei 13, Araki's current Reiatsu only now barely qualifies as captain-level.

After all, the original Gotei 13 was notorious for its ruthlessness. Each captain had fought their way to the top through countless bloody battles. They were in no way comparable to the pampered "hothouse flowers" cultivated by the Shino Academy in later generations.

This was the era of the slaughter-hardened original Gotei 13, where every captain was a fearsome killer.

—

Finally achieving Second-Class Reiatsu after all these years, Araki couldn't help but feel a sense of accomplishment.

"How many years has it been? I've finally stepped into second-class reiatsu."

Araki couldn't even remember how long he'd been in this world.

He only remembered playing an open-world One Piece-themed RPG, grinding for two and a half days straight, when suddenly, in the blink of an eye, he found himself no longer in his cozy bedroom but in a remote district of the Rukongai.

At first, he didn't think much of it.

After all, he hadn't crossed over alone—his maxed-out RPG character stats from the game had come along for the ride.

Top-tier swordsmanship rivals that of a Grandmaster Swordsman. Perfect mastery of the marines Six Powers martial arts. Superhuman endurance capable of recovering from fatal injuries with rest. Endless stamina that allowed him to fight for three days straight without tiring. Fully awakened Haki in all three forms. And the overwhelmingly powerful, awakened Ope Ope no Mi.

With such a ridiculous suite of abilities, Araki was confident he could thrive in any world.

Even if he had crossed into the dangerous world of One Piece, he could have simply avoided the Admirals, Yonko, and Celestial Dragons to live out a peaceful life.

But his optimism crumbled when he saw a figure clad in black, wielding a katana-like Zanpakutō.

"A Shinigami."

It was at that moment that Araki's heart sank.

—

Araki quickly realized he hadn't crossed into One Piece. Instead, he had arrived in the Bleach universe.

This revelation snuffed out the spark of excitement he initially felt about being isekai'd.

Compared to One Piece, the world of Bleach was far more dangerous—especially in the Rukongai, where Araki found himself.

To survive, he had no choice but to become a Shinigami.

Yet, even as a Shinigami, the threats he might face were on another level entirely.

From Yhwach's reality-altering Almighty to the Sternritter's overpowered Schrift abilities like The Miracle and The Deathdealing, this world was filled with absurd powers beyond reason.

After years of wandering and struggling to survive, Araki stumbled upon the Genji Dojo and became an apprentice to its strict master.

Despite his teacher's harsh training methods, Araki's swordsmanship rapidly improved thanks to his existing foundation from One Piece. Within decades, he mastered every technique his teacher had to offer.

During his graduation duel, he even managed to leave a scar on his master's head—a feat that earned him the title of "Genryū" and the certification of a fully licensed swordsman.

This event marked a turning point for Araki. His system adapted, merging his One Piece attributes with the mechanics of Bleach.

—

Among the new features of his system was a dormant Fullbring: [Flower That Never Withers.]

Curious about its potential, Araki opened its description.

[Fullbring: Flower That Never Withers (Unawakened)]

[Ability: Binds the life forces of the user and a loved one. As long as one survives, the other cannot die. Any injuries sustained by either party can be healed using Reiatsu. Until both are out of Reiatsu, neither can be killed.]

Upon reading this, Araki's eyes lit up.

"This is a god-tier ability! It's purely defensive, but as a life-saving technique, it's unbeatable!"

"Let me check the awakening conditions."

Araki tapped on the awakening requirements.

[Awakening Condition: The target must have at least 80 favorability toward the user and be someone the user loves.]

—

A long pause followed as Araki processed the absurdity of this condition.

"Wait… Other people's Fullbrings powers require items, and mine needs a person?!"

Although the thought amused him, Araki decided to focus on the benefits.

What truly caught his attention was the system's note:

[Note: The initial bond determines a permanent power bonus. The stronger the target's Reiatsu, the higher the Fullbring's potential.]

Understanding this, Araki made up his mind.

"To maximize this ability, I need to bond with the strongest woman in the Soul Society."

"Got it. I'll start by marrying Retsu Unohana."

—

With newfound determination, Araki set his sights on the infamous First Kenpachi.
