Ereyan finished reading the rule book in his home, before grabbing his satchel and heading out the door. He had an interesting ability to manipulate kinetic and thermal energy. At a glance, most would simply assume that this meant he could create shock waves, or heat things up... but no, with a little imagination and an education in the sciences, you could do so much more with it. That was why he was attending the school. His power required two things to be used effectively. Imagination, and a fundamental understanding of the physics of the world. He certainly had the first bit, but needed to know everything he could about the second. Also, he did not want to use his power solely for himself. The utility of it would make him a fine assistant to a master. Sprinting down the road to get to the school on time, he increased his kinetic energy to accelerate to a fairly good speed, allowing him to get there in a timely fashion. On the way, he nearly knocked over Tsuna as he rounded a corner.
He quickly checked to make sure they were both fine, before speeding off again.
