There were quite a few test participants this time.
The entire Astraea Familia decided to join—especially after hearing Tsuna's brief explanation, they were all eager to participate.
The Loki Familia, of course, couldn't send everyone. Only a few familiar faces were selected for the trial.
But the moment they stepped through the gate of the Training Space, everyone's expressions changed drastically.
"The pressure here's insane."
Alise hadn't expected the place to feel so heavy.
"Just walking feels like there's a mountain strapped to my back," Kaguya muttered, her movements stiff and mechanical. She tried to stretch or shift, but every motion felt sluggish and clumsy.
The others didn't speak. They simply waited in silence.
Even breathing became a struggle. Their lungs fought to draw in enough oxygen, and soon everyone's breathing turned rough and uneven.
"Even... breathing is exhausting," someone gasped.
"The air's burning hot. It hurts."
Ais felt the discomfort immediately—each breath scorched her throat.
"The air feels like it's burning because this space's temperature is far higher than normal," Finn analyzed quickly. "There's not much oxygen stored here, but the heat makes even that hard to breathe. Under this kind of gravity, even simple movements drain you. The hotter air forces your lungs to work harder, which burns your body's oxygen faster, increasing fatigue and forcing your muscles to adapt. It's... a brutal cycle of physical compression."
As he spoke, everyone felt the oppressive weight pressing down harder and harder.
What a hellish place for training.
"Exactly," Tsuna confirmed. "You're spot on, Finn."
Finn's analysis was sharp, and Tsuna nodded in approval before adding precise data of his own.
"To be specific, mornings here stay around fifty degrees Celsius, while nights drop to minus fifty."
Gasps rippled through the group.
"With such extreme environmental pressure," Tsuna continued, "I'm confident everyone's physical conditioning can reach its absolute limit."
His gaze then shifted toward the Hiryute sisters.
"Last time outside, Tiona and Tione both trained under one times gravity," he said. "Even that simple training produced remarkable results."
"That's right!"
Tiona stepped forward eagerly, nodding as countless eyes turned toward her.
"My sister and I trained for just a few days under one times gravity, and we pushed both our Strength and Endurance stats all the way to the limit."
The word "limit" sent a ripple through everyone's hearts.
Every adventurer knew that the Falna's ability stats capped at 999.
If Tiona and Tione had actually reached that threshold through training, then the effectiveness of this method was beyond question.
The earlier complaints about the suffocating environment instantly vanished.
One by one, everyone's eyes sharpened, filled with determination.
For an adventurer hungry for power, this was irresistible.
Then Tsuna dropped an even heavier revelation.
"In the Falna system, ability improvement only occurs through targeted training. If you want to raise Endurance, you need to subject your body to pressure. To increase Strength, you have to resist greater force. Every stat only grows when your body is pushed to its very limit."
He paused, letting that sink in.
"The Falna's greatest advantage is how it quantifies growth. After training, you can see exactly how much stronger you've become. And once updated, your stats rarely decrease—not even with age."
"But," he added, "there's a catch. The higher your level, the harder it becomes to raise each stat. Progress slows to a crawl. Which means, to keep growing, you must endure even greater external strain. Only through extreme, overload-level training can your stats rise dramatically."
He smiled faintly. "That's what this test is all about."
Tsuna's gaze returned to the Hiryute sisters.
"Even stats that have hit the limit might still be breakable. Tiona, Tione—999 isn't the Falna's true ceiling. Surpassing 1000 is possible."
Everyone froze.
"999 marks the body's natural limit," Tsuna continued calmly. "But no one ever said that limit can't be broken."
"Seriously!?"
Tiona and Tione's eyes lit up like twin stars, excitement sparking through them. The idea of surpassing their own limits was thrilling beyond words.
And it wasn't just them. Every single adventurer in the room felt their pulse quicken.
"The topic of breaking limits, huh..." Finn murmured, his curiosity unmistakable.
If their stats could go beyond 999, that meant their growth had no ceiling.
Finn and Gareth exchanged a look—silent but blazing with shared excitement.
With a possibility like this, what kind of adventurer could say no?
"Can we start already?"
Bete's voice came rough and eager. His usual aggression was gone, replaced by pure, burning hunger for power. His gaze flicked toward the Hiryute sisters, his heart pounding wildly. He couldn't stand waiting any longer.
"Not quite yet."
Tsuna shook his head lightly and continued his explanation.
"This space consumes a lot of stamina and water. Overtraining can easily cause dehydration or dizziness. So I've stocked it with plenty of supplies."
"The food looks a bit like clay," he admitted, "but it's surprisingly easy to eat and digest—perfect for energy replenishment."
He then gestured toward a set of containers nearby.
"And since the training intensity will be high, everyone should change into the special exercise suits I've prepared. They're made to stretch automatically, so size won't be an issue. The material is breathable and sweat-resistant."
He added, "And don't worry—ladies, even if the outfit fits snugly, it won't expose anything it shouldn't."
A few of the women looked visibly relieved.
"That's all for the briefing. You can change in the separate rooms by gender. The next half-day is free training time."
"After that," Tsuna continued, "Miss Loki and Goddess Astraea will be ready to update everyone's Falna. You'll get to see exactly how much you've grown."
As he finished, the tension broke, and people began moving.
"Let's do this!"
Unable to hold back their excitement, Tiona and Tione shouted together and dashed straight into the women's changing room.
Their laughter echoed behind them—pure joy, uncontainable and bright.
