what if Shigaraki was Infinite the Jackals reincarnation

A New Threshold of Speed

As the weeks went by, Izuku adjusted to training with the turtle shell, and he was surprised at how quickly his body adapted to the weight. The first few days were grueling, filled with aching muscles and fatigue, but he persevered, driven by his goal of becoming a well-rounded hero. Now, as he strapped on the shell for another training session, he felt a familiar surge of energy. He had gradually regained some of his speed, his legs becoming accustomed to the extra weight. It was still challenging, but now, instead of feeling sluggish, he felt a newfound sense of control.With a determined expression, he took off down the track, each step pushing against the turtle shell's weight. He could feel the ground beneath him and the wind rushing past his face as he ran faster than he had in weeks. He wasn't just moving; he was gliding, albeit at a controlled pace."Let's see what I can do now!" Izuku shouted to himself, a grin spreading across his face as he pumped his legs harder. He reached a speed that felt reminiscent of a character from a video game he loved—Mario at full speed. It wasn't the dizzying heights of his previous velocities, but it was fast nonetheless, around **25 miles per hour**. This was slightly less than what he believed Tenya Iida could achieve, but it felt like a major milestone for him.As he zipped around the track, he could hear his instructor's voice calling out encouragement from the sidelines. "Good job, Izuku! Keep it up! The weight is still there, but you're getting faster!"Izuku concentrated, pushing himself even harder, determined to break through the barrier. With every step, he could feel his muscles working in harmony, every fiber of his being aligning with his training. He could already envision himself in the tournament, showcasing not just his speed but also the strength he had developed.As he rounded the final bend, he focused on the finish line, and with a final burst of energy, he propelled himself forward, crossing the imaginary line with a triumphant shout. Panting heavily, he slowed to a stop and turned to his instructor, who nodded with a proud smile. "You're doing great, Izuku! Keep training, and by the time of the tournament, you'll be even faster!"Izuku's heart swelled with pride. He still had work to do, but for the first time, he could see the light at the end of the tunnel. He was on the path to becoming the hero he'd always dreamed of being, and every step—whether fast or slow—was bringing him closer to that goal.
