Saimin Regulation - Extra-Arc 15: Houjou Kokoro Regression-Arc

This is a story about a legend, of one that can never be forgotten.
Summer, first time down the mountains in 16 years, after being raised by his 3 masters and Fairy sister.

‘Why won’t you follow the Rules of society?’ The rules are the tool made by the strong, so I follow my own rules.

‘Why won’t you just use your brain instead of your brawn?’ Idiot! Have you ever seen anyone use their brain, to get back at an ant that bites them!? No, they just casually step on it.

‘Oh, everyone says you’re a first-class beauty huh?’ well, I’m sorry but even you are not qualified to be my wife. Only a ‘Summer class beauty’ is worthy enough!

‘My enemy is sick?’ Oh, don’t worry, even if you’re on your last breath and I feel it’s beneath me to slap shot you dead. I’ll just fix you up and then beat you!

‘Who am I?’

“I am Summer in the spring, the autumn, and the winter, I’m the world’s first above the heavens!”

Follow me, Summer Day as I step by step become known as the world’s first master, the world’s first doctor, the world’s richest man…… a lot of other world’s number one, but most importantly, The worlds happiest man.

Everything has to be studied to understand its meaning.

The traveler Chiba Shiroishi picked up a book called “The Will of Fire”.

When I opened it, the things on it had no nourishment, and the history of Konoha Village had no age, but the words ‘Will of Fire’ were written on every slanted page.

Shiraishi couldn’t sleep, so he took out the book “The Will of Fire” and read it carefully in the middle of the night, only to see the words in the cracks. The whole book was written with two words – pyramid selling!

Shiraishi felt hesitant and fearful for a while, and he decided that sooner or later, he must escape from this MLM brainwashing organization called Konoha!

Japan – National News BroadcastThe polished news anchor sat upright, her gaze sharp as she adjusted the stack of papers before her. The newsroom behind her hummed with quiet urgency, the weight of the moment settling over the broadcast.“Authorities are baffled by a sudden and unexplained surge in sleep-related deaths across Japan,” she began, her voice steady yet tense. “More and more citizens are passing away in their sleep without any prior health concerns. Experts are working tirelessly to determine the cause, but no clear explanation has emerged. Authorities urge the public to remain vigilant and report any unusual symptoms before bedtime.”A graphic appeared, displaying the spike in fatalities over the past month. Behind her, unsettling photographs flickered across the screen—blurred images of individuals found in their beds, their faces frozen in expressions of terror.The anchor’s tone shifted. “Health officials recommend citizens avoid excessive fatigue and maintain healthy sleep habits. More updates will follow as investigations continue.”---United States – Paranormal PodcastIn a dimly lit podcast studio, the host leaned forward, his eyes wide with curiosity. Across from him, a rugged man in a worn flannel shirt, gripping a faded photograph in one hand and a beer can in the other, leaned back in his chair.“So, you're telling me you saw this creature firsthand?” the host asked, clearly intrigued.The man scoffed, shaking his head. “Damn right, I did. Ugly thing had wings bigger than my body—slow but sneaky. Thought it could steal my pigs again, but I was ready this time—camera in one hand, shotgun in the other.”He slammed the table for emphasis, then shoved the blurry image toward the host. The photograph depicted a small, red-skinned humanoid figure with large, bat-like wings, its eyes glowing faintly in the darkness.“Spit, the thing didn’t know what hit it when I fired!” the man chuckled, his voice full of excitement.The host held up the picture to the live chat. “Alright, what do you think? Mothman? Demon? Or is our friend here just seeing things?”The chat exploded with theories—some skeptical, others eager for the investigation to continue.---China – Liangyuan Street MarketSurveillance footage from a bustling night market in China captured a chilling scene. A woman in a red qipao walked gracefully through the crowd, her figure striking in the soft glow of lanterns.Suddenly, she paused. Her body flickered—like a glitch in a video—before vanishing completely, as though she had never existed.The footage zoomed in, replaying in slow motion. In the final frame before she disappeared, her face distorted unnaturally, her eyes hollow and empty.The screen cut abruptly to black.
