Shimaidon. A term Natsuo often blurted out with a triumphant tone, recounting his threesome experiences with two sisters.
Ren used to only be able to listen to Natsuo boast. But now, the situation was different. He himself had just experienced something similar with Masha and Alya.
11:15 PM.
In one of the bedrooms of the new house, Ren gulped down mineral water directly from the bottle, trying to moisten his parched throat.
On the rumpled bedsheets, Masha and Alya lay naked in a state of unconsciousness, their bodies go limp due to the overwhelming wave of euphoria after an intense fucking session.
"In my previous life, I've often fucked blood-related sisters, but nothing has ever been this much fun. What's the reason?"
Ren observed the two girls sprawled on the bed.
"Could it be Masha and Alya's status as heroines that makes them feel more special and provides a different sensation from other women?"
Not finding a satisfactory answer to his doubts, he decided to stop thinking about it.
"Itsuki will give birth soon, and Ai is menstruating. Of course, it is impossible for me to fuck them in such conditions. Oh well, I'd better practice Sun Breathing."
Taking a black bathrobe from inside the closet, Ren left the room of the two still-sleeping Kujou sisters.
He walked out of the room, down the silent hallway of the house, and headed towards the spacious rooftop.
He had deliberately chosen the open area because of its adequate size for various activities, including physical training. Under the star-studded Tokyo night sky, Ren prepared to begin his training.
◆━⊰✧⊱━◆
Tsugikuni Yoriichi was a legendary swordsman born in the turbulent Sengoku Era. He was the first individual to successfully master and even create a revolutionary breathing technique that later became known as Breathing Styles.
However, the Breathing Style created and used by Yoriichi was said to possess incredibly immense power, so much so that it demanded extremely strict physical requirements from the user's body. The difficulty level for learning it was almost impossible for ordinary humans.
As a result, various Breathing Styles that were easier to learn and master were later derived from the original Breathing Style used by Yoriichi.
Water Breathing, Thunder Breathing, Flame Breathing, Stone Breathing, Wind Breathing. These were the five basic Breathing Styles—these were the five basic Breathing Styles, all of which were branches originating from the foundation laid by Yoriichi's Breathing Style.
And at the pinnacle of the hierarchy of all Breathing Styles stood a technique that was the source of everything, the origin of all existing branches: Sun Breathing!
"Huuu... Haaa..."
Sitting cross-legged with his back straight like a meditating monk, Ren began a series of inhalations and exhalations that would seem to lack any clear pattern to the untrained eye. He inhaled deeply in tremendous amounts, maintained his still body position, and demonstrated a breathing rhythm that felt strange yet full of power.
His exhalations, slow yet steady, created a burning and destructive sensation for anyone nearby, as if the air he exhaled contained invisible embers. However, at the same time, Ren himself felt an endless flow of energy flooding every cell of his body, making him feel increasingly strong and invigorated.
"Huuu... Haaa..."
Along with each of his regular breaths, the mysterious aura emanating from Ren's body grew stronger and more intense. A faint golden light began to envelop his body, radiating from every pore.
At that moment, anyone who saw him might feel that he was no longer merely an ordinary human but had transformed into a manifestation of the sun itself, radiating boundless warmth and power.
'Now I understand why only a handful of individuals managed to cultivate Sun Breathing.'
'The physical fitness requirements are absolutely insane! Sun Breathing demands extraordinary lung capacity, muscle strength that transcends human limits, and seemingly endless endurance. No wonder it's almost impossible for ordinary humans to master.'
'I myself can do it relatively easily because of my body's physiology as a Campione. My physical strength, speed, and endurance far exceed the limits of normal human capabilities.'
Ren felt every fiber of his muscles and bones pulsating in harmony with his breathing rhythm.
Repeating this seemingly monotonous yet necessary process for approximately thirty minutes, Ren finally managed to fully master Total Concentration Breathing. He felt a stable and constant flow of energy running throughout his entire body.
Using Total Concentration Breathing essentially enhances the user's natural physical attributes and abilities while still remaining human. These attributes include superhuman strength, speed, stamina, resilience, durability, and the mental faculties needed to keep up with their superhuman bodies, such as faster thinking processes and reaction times.
"Huuu... Let's begin practicing swordsmanship with Sun Breathing."
Standing upright, Ren extended his hand and pulled out a katana from his magical storage dimension.
"Sun Breathing—First Form—Dance."
With a graceful yet deadly movement, Ren unleashed a horizontal slash forward.
*SWOOSH!*
A curved slash split the air with astonishing speed. His slash was so fast that it looked like a beam of sunlight streaking through.
As the sword blade cut through the air, flames suddenly ignited along its path, forming a trail of blazing sun, cleaving through the void and the surrounding atmosphere.
"Sun Breathing—Second Form—Clear Blue Sky."
Ren seamlessly transitioned to his next attack, his sword movements feeling natural and without pause.
*SHUA!*
Leaping high into the air with incredible force, he twisted his body mid-jump and brought down his flaming sword from above, carving another solar trajectory in the night air.
*SWOOSH!*
As the tip of the sword slashed the concrete surface of the roof, the flames enveloping it transformed into a spinning wheel of fire with terrifying intensity, spreading rapidly in all directions.
Wherever the wheel of fire passed, everything it touched was scorched by the devastating flames, leaving behind horrific burn marks and sword slash traces that seemed capable of splitting an entire mountain peak in two, displaying a power that truly transcended the limits of imagination.
"Okay. Enough. If I keep practicing here, I'm worried this newly bought house will collapse in my own hands before we even get to enjoy it."
Not wanting his new house to be torn to pieces by his excessively powerful swordsmanship practice, Ren decided to continue his training session at another, safer location.
After all, Sun Breathing consisted of thirteen different sword forms, and he had only just practiced two of them. There were still many other deadly techniques he wanted to fully master.
Without wasting any time, Ren chanted the activation incantation for his Divine Authorities Solar Flash.
"The sun's brilliance, radiate your light within me! Carry this body across space and time, leaving behind a shadow that even the world cannot catch!"
Instantly, Ren's body was enveloped in an intense light. In the blink of an eye, he entered Godspeed mode.
*WHOOSH!*
His figure transformed into a beam of pure light and shot off at a speed that defied reason, leaving ripples of energy in the air as the only trace of his existence.
He vanished from his rooftop as fast as lightning, heading towards a safer and more secluded training location.
