A Horimiya Fanfic I guess? (with some chat group/multiverse)

Oh hey guys, does actually someone remember this? It would be fun if someone actually does.

So actually sorry for not continuing the other fic, it was too cringe to my own test even if some people loved it (especially after chapter's five twist), I had too many ideas too, but that period was difficult to me so I didn't have the motivation to actually write another chapter.

So here's another fic, hope you would like it.

As Ryuu sat in front of his computer, playing his video game, he couldn't help but feel a sense of boredom and emptiness. 'It's been 17 years since I reincarnated into this world, and nothing particularly exciting has happened,' he thought to himself.

He stood up from his chair and walked over to the window, opening it to let in some fresh air. The morning sun was shining brightly, and he realized that he had spent the entire night playing Minecraft, a game he had developed a particular fondness for. As he looked out, he couldn't help but notice his own reflection in the window. He was handsome, with dark black hair and piercing black eyes. He was tall, at least 6 feet tall, and had a well-built physique.

He took a cigarette from a pack and lit it, taking a drag as he remembered his past life. He remembered the first time he found himself in this world, abandoned by his parents on the streets in the middle of winter. He had to steal and do whatever it took to survive, including eating out of trash cans. He remembered the cursed night when he tried to steal from someone and failed, only to find out it was the leader of a powerful gang. This event changed his life forever, leading him to become the strong and capable person he is today.

The leader saw potential in the young Ryuu and offered him a deal: he would provide him with food and clothing, and in return, Ryuu would work for him. Ryuu accepted and spent years doing missions for the gang, becoming stronger and more skilled with each passing day. It was during this time that he picked up the habit of smoking.

When Ryuu was 15, the gang was dissolved due to the betrayal of one of its members, who gave important information to the government. Ryuu, grateful for the gang taking him in, but not willing to sacrifice his life for it, decided to flee and create a new identity for himself in the suburbs of Kanto, using the connections and money he had accumulated over the years.

Now, as Ryuu stood in front of the window, he remembered his past life and decided to take a shower. He had a near-perfect physique, with a six-pack and scars all over his body, mostly on his back and hands. He had a tattoo of a dragon in yakuza style on his muscular back, as well as some piercings that were not visible. He also wore a gold chain and a silver bracelet.

 After his shower and breakfast, he dressed in his school uniform for Katagiri high school and put on his gloves. He couldn't help but think that he was bored and that he never wanted to study in the first place. It was just a backup plan to have a diploma and work as an employee if his plans of freelance do not succeed.

As Ryuu walked to school that morning, he couldn't shake the feeling of emptiness in his heart. He loved walking in the mornings, as Japan was particularly beautiful during that time of day. Arriving at his high school, Ryuu immediately went to his class. He had no friends and wasn't particularly well-liked by his classmates, due to his reputation as a delinquent after an incident early in the school year.

'Another boring day,' he sighed to himself as he put his head down on his desk and pulled out his phone. Suddenly, he received a strange notification that read 'Welcome to the Chat Group, Admin.' Ryuu's eyes widened for a moment before he quickly composed himself. He couldn't shake the feeling that something big was about to happen. 

He decided to check this later as this was not the time or the appropriate place to it.
