Especially those large mats piled up at the very back, unless there's some special large-scale event, no one ever uses them.

"..."

Yan Huan glanced around the room, then moved toward the depths where Sakuragi Hitomi had earlier retrieved the shovel.

Sure enough, the shovel was still standing behind the mat, completely unnoticed by others.

Yan Huan picked up the shovel single-handedly, but as he lifted it, something underneath caught his attention.

It was...

A name tag with the word "illness" on it.

Yan Huan had seen this name tag earlier when Sakuragi had fallen, but now it was covered in blood stains and dust.

Staring at the alarming blood stains on it, Yan Huan couldn't help but frown.

He reached out to pick up the name tag and brushed off the dust.

And as it happened, the action of dusting flipped the name tag over, revealing the text on the back.

"Birth Certificate"

"Pregnancy Date: Heisei Year 21, January 1, 2:48 PM"

"Pregnancy Record: Premature birth, underweight infant"

This seemed to be a birth certificate from Ying Country, but all the text below was too blurred to read.

Instead, there were several lines of scarlet text,

"Greetings, unknown Sakuragi. I am the sickly Sakuragi, and this is my barrier located in the school equipment room.

"When you see this text, I must already be dead. This line of text will only unlock 24 hours after my death.

"Whichever Sakuragi sees this line of text, please keep this birth certificate safe. It can unlock the 'birthing chamber' at the top level of all barriers.

"Through the birthing chamber, you can find the true location of 'her' barrier. Please be very careful not to lose this, or else...

"Now, run!"

Staring at the scarlet words "Run" at the bottom, Yan Huan's frown deepened.

Just then, not far behind him, a female voice suddenly and eerily rang out,

"President, what are you doing～"

"!!"

Yan Huan's eyes narrowed, and in a flash, he swiftly tossed the birth certificate to the ground and sat on it, preventing it from being seen.

He forcibly endured the discomfort of goosebumps all over, sweating as he turned to look back...

...Only to see Yuanlina standing a short distance away behind the mat, grinning at him with a naive smile, holding a bag of oranges she had just bought from the shopping street.

Behind her, there were a few girls in sports outfits.

They were here to retrieve equipment needed for the afternoon's physical education class.

Due to the angle, she could only see Yan Huan's head crouching down and had no idea what he was doing.

That's why she curiously asked.

But seeing Yan Huan's big reaction, she was instead startled and panicked,

"Pres...President, what's wrong? Don't scare me?!"

"..."

Yan Huan gasped, staring blankly at Yuanlina who was instead frightened by his own movements, feeling a great weight lift from his heart, his face turning extremely dark.

"Yuanlina!!"

"Hey hey hey?! Why is the President angry?!"

Yuanlina clutched her chest, blinked her big watery eyes, looking utterly innocent.

Yan Huan sullenly slipped the birth certificate under his seat into his pocket, picked up the shovel, and walked out, reaching into her plastic bag to grab the largest orange,

"This orange is mine now, as compensation for my mental distress."

Yan Huan declared domineeringly.

"Darn it! I picked that biggest one for so long! President, I'm not playing with you anymore!!"

"How many times have you eaten my fruit salads before? Hmm?"

Upon hearing this, Yuanlina's eyes immediately spun around, touching the back of her head as she quickly changed her expression,

"Teehee, I'm just joking, I'm the world's best with the President～

"Here, President, have more oranges, they're very nourishing!"

Yan Huan's mouth twitched awkwardly, unable to speak for a long time.

"..."

...

...

"Hmm..."

In the afternoon, at the Hentai Club.

Yan Huan frowned, looking at the birth certificate in his hand, contemplating its extremely rich information.

Sure enough, the Sakuragi he encountered the other day who fell flat was the sickly Sakuragi.

And the one later was an imposter in the daily interactions.

Sickly Sakuragi...

Dead...

The moment these two words appeared, Yan Huan instantly connected some dots...

Could it be because the sickly Sakuragi died, the current Sakuragi was able to escape the barrier and became so healthy?

If that's the case, then another problem arises:

With Sakuragi's personality dead, what happens to Sakuragi's true self?

"..."

At last, Yan Huan seemed to have figured out much of the current situation.

First, the current daily Sakuragi is indeed a personality fragment.

Combining the sickly Sakuragi's words "my barrier" and "her barrier," this point can be inferred.

Because according to Little Thumb's theory, the true self would have complete control over all barriers, it wouldn't speak this way.

Alright, with that established, the question arises:

Where did Sakuragi's true self go?

Secondly, this personality seems to be hunting other personalities representing negativity.

Even though Little Thumb said these personalities would certainly not harm Sakuragi.

Moreover, Sakuragi's improved health seems like a good thing...

But looking at the birth certificate stained with blood, Yan Huan still felt a deep unease.

Sakuragi, where on earth have you gone?

Yan Huan felt a bit troubled, yet cautiously kept the birth certificate as the sickly Sakuragi instructed.

Then, he lifted his gaze to look at Spencer, who was wrinkling her face while doing homework in front of him,
