### Chapter 1: The Devil in Disguise

In the bustling heart of Tokyo, where the skyscrapers kissed the sky and neon lights painted the night, lived Tony Nakashima. Born into the affluent Nakashima family, Tony was the epitome of perfection: hot, handsome, and highly intelligent. His father, a powerful business tycoon, ensured Tony received the best of everything—education, lifestyle, and privileges.

Tony had just been accepted into the prestigious Shujin High School, known for nurturing Japan's future leaders. His father gifted him a luxurious apartment near the school, complete with every amenity a teenager could dream of. Life seemed perfect on the surface, but Tony harbored a secret talent that set him apart. He could manipulate anyone and everyone without them realizing it. His charm and charisma were unmatched, making him the true definition of a devil in disguise.

Tony strutted through the school gates on his first day, his confident aura drawing everyone's attention. Girls giggled and whispered as he passed, captivated by his good looks and effortless charm. He flirted with ease, leaving a trail of infatuated admirers behind him. It was a game to him, a test of his abilities.

That evening, in the solitude of his apartment, something extraordinary happened. As Tony lay on his plush bed, a sudden flash of light illuminated the room. A beautiful, ethereal figure appeared before him—a girl with cascading silver hair and striking violet eyes.

"Greetings, Tony," she said, her voice melodious and captivating. "I am the Infinite Money System."

Tony blinked in disbelief. "A system? You mean like in those fantasy stories?"

"Precisely. I am here to aid you in your endeavors. You may call me Luna," she replied with a playful wink. "However, there's a twist. You can only use this system on girls who rate 9.2 or higher in beauty, according to my judgment."

Tony's eyes gleamed with interest. "What exactly can you do?"

Luna smiled, a mischievous glint in her eyes. "I can show you your stats and the stats of others, including their affection levels towards you. Additionally, I provide infinite money, but it can only be spent on these high-rated girls. As their affection for you increases, you gain points which can be used to enhance your intelligence, strength, agility, and luck. Once you reach 95% affection from a girl, you get 35% of the money spent back and can copy and upgrade her abilities."

Tony's mind raced with possibilities. "And you think I lack the skills to flirt and charm girls?"

Luna raised an eyebrow, curious. "Let's see your stats before I make any judgments."

With a wave of her hand, a translucent screen appeared in front of Tony, displaying his stats:

- **Name:* Tony Nakashima**

- **Age:** 17

- **Charm:** 100 (MAX)

- **Intelligence:** 90

- **Strength:** 85

- **Agility:** 88

- **Luck:** 75

- **Affection Points:** 0***

Tony grinned at the screen, particularly proud of his maxed-out charm.

"Impressive," Luna admitted. "But can you handle the challenge?"

Tony smirked. "Watch me."

The next day at school, Tony decided to test Luna's abilities. He scanned the cafeteria, his eyes settling on Aiko, the most popular girl in school, known for her beauty and elegance. Luna's voice echoed in his mind, "Target acquired. Beauty rating: 9.4. Affection level: 50%."

Tony approached Aiko with his trademark confidence. "Hey, Aiko. Mind if I join you?"

She looked up, surprised but intrigued. "Sure, Tony."

They chatted effortlessly, Tony's charm weaving a spell over her. By the end of the conversation, Luna informed him that Aiko's affection level had risen to 65%.

Tony spent the next few days subtly showering Aiko with attention and gifts, using the infinite money from Luna. He noticed that as her affection grew, he felt stronger and more agile. Finally, after a week, Luna's voice announced, "Aiko's affection level: 95%. Points gained: 10. Ability: Enhanced Reflexes."

Tony felt a surge of energy as he absorbed Aiko's ability. He also saw a 35% return on the money he had spent. He marveled at the possibilities—this system was more powerful than he had imagined.

Later, in his apartment, Tony reviewed his own stats again, now with added abilities and points to spend:

- **Name:* Tony Nakashima**

- **Age:** 17

- **Charm:** 100 (MAX)

- **Intelligence:** 95

- **Strength:** 90

- **Agility:** 95

- **Luck:** 80

- **Affection Points:** 10***

Luna appeared beside him, impressed. "You exceeded my expectations, Tony."

Tony smiled, his eyes gleaming with ambition. "This is just the beginning. With you by my side, there's no limit to what I can achieve."

Tony's eyes now turned to the broader horizons. One evening, as he was watching a popular variety show on TV, Luna highlighted a new target: a famous idol named Mizuki Tachibana. Her beauty rating was off the charts, a perfect 10 according to Luna.

Luna's holographic image appeared beside the screen, showcasing Mizuki's detailed bio and stats. "Mizuki Tachibana. Beauty rating: 10. Affection level: 20%. Ability: Perfect Pitch and Dancing Skills."

Tony's interest was piqued. This was a challenge he couldn't resist. "Alright, Luna. Let's see what Mizuki has to offer."

---

Tony's plan to meet Mizuki was set into motion. Using the infinite money system, he managed to secure VIP tickets to one of her concerts. With Luna's guidance, he devised a plan to get close to her. At the concert, Tony's charisma and luck played a crucial role. He was selected for a special fan interaction segment, and his charm did the rest.

Backstage, Tony's confidence shone brightly as he interacted with Mizuki. Luna's voice guided him subtly, enhancing his moves and words. Mizuki was captivated, her initial affection level rising rapidly. Over the next few weeks, Tony continued to shower her with thoughtful gifts and attention, always using the infinite money system to its fullest potential.

Luna kept track of Mizuki's affection levels, and Tony felt his own abilities growing stronger. Eventually, Mizuki's affection for Tony reached 95%, and Luna announced the successful acquisition of her abilities. Tony felt a new surge of power as he absorbed Mizuki's perfect pitch and dancing skills.

Back in his apartment, Tony reviewed his enhanced stats:

- **Name:* Tony Nakashima**

- **Age:** 17

- **Charm:** 100 (MAX)

- **Intelligence:** 98

- **Strength:** 95

- **Agility:** 97

- **Luck:** 85

- **Affection Points:** 20***

Luna appeared beside him, her expression one of awe and admiration. "You've surpassed every challenge, Tony. You're truly a devil in disguise."

Tony grinned, his eyes filled with determination. "This is only the beginning. With infinite money and your guidance, there's no limit to what I can achieve. Together, we'll conquer everything."

As Tony's journey continued, he faced new challenges and targets, each more difficult than the last. But with Luna by his side and his devilish charm, there was nothing he couldn't achieve. The world was his playground, and he was ready to manipulate it to his advantage, one girl at a time.

Thus began the legend of Tony Nakashima, the devil who could charm anyone and get anything he wanted, with an infinite money system and a beautiful guide by his side.
