In his room, Light pondered which Advanced Training Card would be the best option to use.

He was leaning towards level 3, now that he had enough Fate Points to 'play around' a bit. Without hesitation, he directly spent 365 Fate Points and a golden card materialized in his hand.

Upon activating the Advanced Training Card, Light was enveloped by momentary darkness before finding himself in an entirely new environment. He was in a spacious room, which at first glance seemed empty, but was equipped with cutting-edge technology capable of simulating various environments and scenarios.

Determined to make the most of the available time, Light dove into an intensive training regimen. For the first 100 days, he dedicated himself to improving his control over his magical powers, diabolic, Sacred Gear, etc., developing new attack techniques, and becoming more deeply familiar with his abilities. Then, for 50 days, he intensified his training by increasing gravity tenfold and simulating various weather conditions such as rain, snow, and extreme heat.

After 200 days of rigorous training, Light, realizing that the room's energy was almost depleted, decided to use the remaining days to practice combat techniques against holograms of adversaries. This final stage of training helped hone his combat skills, preparing him to face real adversaries.

Finally, after 233 days of uninterrupted training, the room's energy ran out. With a sense of accomplishment and exhaustion, Light opened his eyes and found himself back in his room.

"I feel accomplished, but for now..." Light's stomach growled loudly, interrupting his thoughts. He rubbed his protruding belly and murmured, "I'm starving."

Picking up his blinking cell phone, he saw it was a message from Rias Gremory. It was no surprise to him, as he figured she must have gotten his number through the Occult Research Club registration. He read and replied to the message, then left his room and went downstairs to the kitchen.

Upon opening the refrigerator, he saw there were still leftovers from lunch. He took a plate, put the food on it, and warmed it up in the microwave.

"Light?" His mother's voice sounded as she entered the kitchen.

"Yes, mom?" Light turned to her, already anticipating the question that would follow.

"Don't you have a prep course today?" she asked, confirming his suspicions.

"Yes, I will go after eating." Light lied without changing his expression. "It's still early, I have time."

"It's already 6:20, it's not early," she retorted, looking at the clock on the wall.

"It is early," Light insisted, with the same calmness as always.

Light's mother scratched her head and sighed. She knew it was useless to argue with him when he was determined. Anyway, he always got good grades, so she didn't need to worry too much.

Taking a glass of milk, she drank and, before leaving the kitchen, advised, "So, eat quickly and then go to the prep course."

"I know, mom," Light agreed, although he had no intention of going to the prep course. For him, it was completely unnecessary now to go to the prep course and lead a normal life.

Besides, Rias Gremory had sent a message asking to meet him at the Occult Research Club.

The hunger he felt was greater than he expected; only after having three servings did he feel satisfied. Although in the training room he ate cereal bars that used up a bit of energy, he avoided eating too much, as he didn't want to spend too much energy on it.

After taking a shower and changing clothes, he combed his hair and was ready to leave.

To disguise, of course, he took his backpack. Another reason was that he did not feel comfortable leaving the Death Note alone at home.

"I'm leaving." Saying this, he left without waiting for a response.

On the way, he thought about grabbing the Death Note. Using a concealment spell, he opened a pair of wings and started to fly with the Death Note in his hand.

How to use: The human whose name is written in this notebook will die. The notebook only works if the writer has the person's face in mind when writing the name. Thus, people with the same name will not be affected. If the cause of death is written within 40 seconds after the person's name, it will happen. If the cause of death is not specified, the person will die of a heart attack. After the cause of death, the details of it must be written within 6 minutes and 40 seconds.

He closed the book and stored it again. Before, he couldn't accurately feel the demonic energy in the book, since he had just become a Devil, but now that he spent 233 days training, he had very good control in various senses and even well-developed his current abilities.

Suddenly, while he was flying, he felt that the purple lightning he placed in Ai Hoshino was found by someone and removed from Ai Hoshino.

"..."

Light shot at full speed from the location that was sent to him the moment the purple lightning self-destructed to send him the exact location.

━━━━ ≪?￢ﾉﾫ ━━━━

Ai Hoshino was discovered by the group of Sona Sitri. They quickly arranged a meeting with her, resorting to the use of considerable financial resources, as soon as a high amount was offered, the businessman managing Ai's career did not hesitate to accept.

Certainly, there were other ways to arrange this meeting, but Sona and her group opted for a more civilized and practical method.

Sona Sitri and her group were gathered in a separate room of a café, anxiously awaiting Ai's arrival. The room was cozy and well decorated, with comfortable armchairs and a coffee table. It was evident that Sona and her group were trying to create a comfortable and inviting environment for the meeting. They were all sitting, talking in low voices while checking the clock from time to time.

Ai Hoshino was nervous as she opened the door to the meeting place.

"I apologize for being late..."

Upon entering, she was taken by surprise to find several beautiful women and no men in the room. A nearly tangible relief enveloped her, as she feared getting involved in something sinister and even mentally prepared for it.

Ai's surprise quickly turned into curiosity as she wondered about the purpose of the meeting and what that group of women wanted from her.

Sona looked up at Ai and said, "No, you arrived right on time. Come in and sit down."

Before Ai could sit down, Tsubaki Shinra noticed something strange in Ai's body, and in the next instant, she was already in front of her, grabbing something in her hand with a quick movement.

"That..." Tsubaki felt confused. She did not recognize that power. It was a kind of lightning thread that did not dissipate, seeming to serve as a locator or something similar.

"It seems that someone is watching her," said Sona, who approached Tsubaki slowly: "I just don't know if this is good or bad."

It was hard to predict whether this represented any danger because, so far, it seemed harmless. However, without knowing the intention of the one who conjured this ability and fixed it on Ai's body, it was impossible to determine if there was any malicious intent directed at her.

Suddenly, the lightning flashed and was destroyed in Tsubaki's hand.

"We have been discovered," said Sona calmly, realizing that their location had been compromised the moment the lightning thread left Ai Hoshino's body.

Meanwhile, Ai was completely confused and oblivious to the whole situation. She did not understand anything they were saying. The only thing she comprehended was that there was something magical attached to her body and that these girls did not seem to be normal humans...

"Are you magical girls?" she asked, blinking her eyes innocently.

After all, Ai was only 15 years old. Although she had already come into contact with something magical, like the voice that used to echo in her mind, she was completely unaware of the supernatural world. Everything she knew about magic came from animes, movies, and series she watched on television in her spare time.

"... No," Sona answered, trying to keep her calm. Being called a magical girl was almost her Achilles' heel. However, she knew that the girl in front of her was unaware of her situation, so she was patient: "We came here today because I wanted to meet you personally and determine if it would be appropriate to invite you to be part of my... group."

"Group? Are you some kind of magical idol girls?" Ai imagined something like singing and dancing using magic... how magical and cool would that be?

A vein seemed about to burst on Sona's forehead. The other girls in the room had to struggle not to laugh, suffocating their laughter with their hands and causing tears to form in their eyes.

Seeing this, Ai became even more confused.

[Why did they suddenly start crying? Did something tragic happen and my question triggered some painful memory? Was I right and they lost a member of the magical idol girls group? Mm... If that's the case, I'm really sorry...]

Ai looked sad now. She began to imagine some sad events that could have made them cry and why the one who seemed to be the leader had such an ugly expression now...

Sona struggled to keep calm, ignoring the voice of Ai Hoshino's heart in her head, and said: "We need to get out of here quickly. This place is unfavorable for us if we have to fight."

"Sona-sama, something is rapidly approaching our direction," Tsubaki informed. She was the only one who managed not to laugh too much, although she found it funny internally, she did not forget that the situation could be serious.

"I know, that's why we need to get Ai Hoshino out of here," Sona affirmed.
