Tatsuya sat in his classroom, trying to pay attention to the lecture but finding his mind wandering. He couldn't shake the feeling that something was different. That was when he suddenly felt a surge of energy coursing through his body. He stumbled and nearly fell out of his seat, eliciting gasps from his classmates.

He quickly regained his composure and made his way to the bathroom, trying to figure out what was happening. That was when he saw it - his hand was surrounded by a bright, pulsing aura. He tried to make it stop, but the more he focused on it, the stronger it became.

Tatsuya was scared. He had never experienced anything like this before and had no idea what it meant. He spent the rest of the day in a daze, his mind racing with questions and fears. He went home early, not wanting to draw any more attention to himself.

Once he was alone in his room, Tatsuya closed his eyes and focused on his powers. He could feel them coursing through his body, begging to be released. He finally let go, allowing the energy to flow freely. The room filled with a bright light, and when it faded, Tatsuya was left standing in a room filled with scattered books and furniture.

He had done it. He had unleashed his powers. Tatsuya was no longer a normal high school student. He was something more, something greater. And with this newfound power came a responsibility - to protect himself and those around him from the dangers that would inevitably come.
