End of [Time Skip]

In his second year, his YouTube channel saw another remarkable surge in subscribers, with his fan base growing exponentially.

This surge in popularity not only brought him fame and recognition but also opened up new opportunities for him to collaborate with other content creators and brands that promote clothes and gym equipment that are useful for doing workouts in their homes.

As his subscriber count soared, so did his dedication to his fitness journey.

Alongside his YouTube success, he embarked on a rigorous workout routine that focused on building muscle mass and strength.

Despite his lean appearance, his body weight surpassed 75 kg, primarily due to his high muscle mass and bone density. His commitment to his fitness goals led him to follow a meticulously planned diet that was rich in calories, protein, and fiber.

He understood the importance of fueling his body adequately to support his intense workouts and muscle growth. His eating capacity even surpassed that of professional bodybuilders in the junior division, as he needed to consume a significant amount of food to meet his nutritional requirements.

His diet consisted of nutrient-dense foods, including lean meats, whole grains, fruits, and vegetables. He carefully calculated his micronutrient intake, ensuring he consumed enough protein to support muscle repair and growth. Additionally, he incorporated a variety of high-calorie foods to meet his energy needs, such as healthy fats and complex carbohydrates.

As a result of all of his efforts, he was able to lift even a person with 90 kg, who was more than 20% heavier than him. Still, he didn't start heavy lifting and bodybuilding waiting for his reach a certain age.

By the end of the second year, his YouTube channel had started to generate a reliable source of income.

With his growing influence, he aimed to educate and empower others to prioritize their health and fitness, emphasizing the importance of a balanced diet and consistent exercise.

Additionally, his popularity can also be attributed to the unexpected appeal of a young child engaging in calisthenics.

Many viewers find it fascinating and inspiring to see someone so young and dedicated to fitness, and they are drawn to his videos to witness his progress and learn from his techniques.

This unique aspect of his content sets him apart from other fitness channels and has helped him gain a significant number of subscribers.

However, despite his success, he occasionally finds himself vexed by a particular group of viewers who seem more interested in his lifestyle in Japan rather than his actual content.

These individuals often leave comments and ask questions about Nao's daily life, the places he visits, and the cultural aspects of living in Japan.

While he appreciates their curiosity, he sometimes feels frustrated that his hard work and dedication to creating quality content is overshadowed by their fascination with his surroundings.

Interestingly, despite the focus on fitness and calisthenics, his videos on diet-making and cooking have consistently garnered higher view counts compared to his workout videos.

This unexpected trend suggests that his audience is not only interested in physical exercise but also in maintaining a healthy lifestyle through proper nutrition.

His expertise in creating nutritious and delicious meals has resonated with viewers, who eagerly watch and try out his recipes, leading to increased engagement and popularity for these types of videos.

By the conclusion of the third year, his number of subscribers had reached 100k.

His popularity extended beyond YouTube, as he became well-known in his school and neighborhood.

Despite his busy schedule, he managed to maintain his exam scores in the top 3, which made his parents even prouder than his accomplishments on social media.

Interestingly, his sister Chiaki kept quiet about the events of the day he became Nao, reassuring him.

Furthermore, no one noticed anything suspicious about his physical strength displayed in his workout videos, and no one ever approached him regarding his extraordinary abilities throughout the years.

This led him to question the existence of monsters and dungeons in the world, feeling as though he had misunderstood his final condition.

'91... 92... 93...'

Nao was doing a 100 vertical push-up challenge in front of the camera.

His determination was unwavering, and his mind focused solely on conquering this grueling vertical push-up challenge.

With each attempt, he pushed himself to the limit, refusing to let exhaustion or pain deter him. Beads of sweat dripped down his forehead, stinging his eyes and clouding his vision, but he blinked away the discomfort and soldiered on.

His muscles screamed in protest, aching and trembling under the immense strain. The weight of his body threatened to overpower him, his arms quivering as they struggled to support his weight.

Every fiber of his being yearned to give up, to collapse onto the floor in defeat, but Nao's determination burned brighter than ever.

The camera, positioned strategically in front of him, captured every moment of his struggle.

It zoomed in on his abdominal muscles, taut and defined, as they strained to maintain stability.

Nao's breath came in ragged gasps, his heart pounding in his chest. The room around him faded into a blur as he focused solely on the task at hand.

He blocked out the noise of his heavy breathing, the pounding of his heart, and the doubts that threatened to creep into his mind.

Time seemed to stretch on endlessly, each second feeling like an eternity.

But Nao refused to give in. He pushed through the pain, the burning sensation in his muscles, and the overwhelming fatigue. Failure was not an option for him.

'...100.'

Finally, after what felt like an eternity, Nao completed the final vertical push-up.

"*PANT* I DID IT!!!... *PANT*... HAHA... I FINISHED IT..."

He collapsed onto the floor as he exclaimed, his body trembling with exhaustion, but a triumphant smile spread across his face.

He had conquered the challenge, defying his limits and pushing himself to new heights once again.

The camera captures every moment of it.

His maroon hair looked glossier, and his body was still lean but packed with muscles.
