After the lunch break, the class resumed.
Ren sat at his desk, staring boredly at the teacher as they droned on about a science lesson. He couldn't help but let out an involuntary sigh.
I already know all of this…
In his previous life, he had already graduated from high school. Listening to the same basic explanations again felt like torture.
Eventually, the class came to an end. Ren grabbed his bag, slung it over his shoulder, and said goodbye to Orihime before leaving.

Once he arrived home, frustration crept into his chest.
How am I supposed to level up like this?
His options were… limited.
He could hunt Hollows—sure—but that came with a major problem: the Shinigami. If Hollows began disappearing without a trace, suspicion would inevitably fall on Karakura Town. He couldn't hunt freely without drawing the attention of the Soul Society.
Ren let out a long sigh, running a hand through his hair.
"I'm really pretty limited right now."
The only thing he could do was wait until the system granted him another dungeon key. Only inside a dungeon could he fight without restraint, clearing everything and squeezing out every last bit of experience without raising alarms.
With a resigned motion, he flicked his hand, closing the system screen.
"Damn it… I need to level up as soon as possible."
...
The next day…
As usual, Ren woke up early—before the sun had fully stretched across the sky. He slipped into his training clothes, did a few light stretches, and stepped outside.
It was time to complete his daily system mission—or as he liked to call it:
The Saitama Workout.
Of course, there was one very important difference.
Ren hadn't gone bald.
In fact, it was quite the opposite. He had only grown more handsome. His body was lean, toned, and powerful, radiating strength without losing the attractive charm that was beginning to catch the attention of passersby.
Thanks to his constant training—and more importantly, his enhanced stats—he could now complete his daily routine with ease. A far cry from the early days, when he'd been so exhausted that his muscles screamed in pain.
"Looks like I got a little carried away this time…" Ren said with a faint smile. "I did more reps than the system asked for."
Opening the system interface, his smile slowly faded as his eyes narrowed in surprise.
...
[Push-ups: 120 / 100]
[Sit-ups: 120 / 100]
[Squats: 120 / 100]
[Running: 12 km / 10 km]
...
Wait a minute…
A flash of inspiration struck his mind, and curiosity ignited in his eyes.
Without a second thought, Ren dropped back down onto the grass and began doing more push-ups. If his theory was correct… then he might have just found a way to level up much faster.
And that thought thrilled him.
Birds chirped overhead. The morning sun warmed the air. But Ren had only one thing on his mind—
Breaking the system through sheer effort and determination.
After several minutes of relentless training, Ren finally stopped and reopened the system window.
What he saw made him frown—
…but in a good way.
...
[Push-ups: 200 / 100]
[Sit-ups: 200 / 100]
[Squats: 200 / 100]
[Running: 20 km / 10 km]
...
"It stopped at double…" he murmured, crossing his arms as he studied the interface.
"I hope this means what I think it does… because if it does, this could be very useful."
Just then, the text of the daily mission began to tremble and distort, as if the interface itself were glitching.
Ren's eyes sharpened with interest.

[Mission Information Updated]
[Hidden Mission Unlocked: "Seeker of Strength"]
...
A calm satisfaction washed over Ren as his theory was confirmed.
Alright… let's see how this goes, he thought, a cool smile forming on his lips.
Without hesitation, he accepted the hidden mission rewards.
...
[Mission Rewards:]
1. Full Recovery
2. +10 Attribute Points
3. Blessed Random Loot Box
4. Cursed Random Loot Box
[Accept Rewards?]
...
Of course I'll accept.
"First things first… let's check the Blessed Loot Box."
Before him, a golden box engraved with ruby-red patterns floated in midair. The lid opened on its own, releasing a soft, heavenly glow. From within, a small orb of light emerged, hovering for a few seconds—
Before transforming into a dark-red key, surrounded by a faintly sinister aura.
...
[Notification!]
[Item Acquired: Key to the Castle of Demons and Hollows]
[Acquisition Difficulty: Rank S]
[Category: Key]
[A key that grants access to the dungeon: Castle of Demons and Hollows]
[Location: Can be used at the Central Tower of Karakura City]
...
"A Rank S dungeon, huh…" Ren muttered.
"This key is a lot different from what I imagined. Does that mean this dungeon even includes Hollows?"
He paused, then smiled.
"Either way… this is exactly what I need."
His eyes burned with determination, confidence radiating from him as a sharp smile formed on his lips.
"I'll level up quickly. I'll grow stronger—strong enough to face the terror that's coming."
But before that… I need to prepare.
"This dungeon is unpredictable," Ren thought seriously.
With that, he turned and headed home, already planning his preparations for the dungeon ahead.
