“Then can you handle something unrelated to our fight?”
“………………………………………………………………………………………………………………………………………”
After turning and looking at the approaching mass of steel, Thor froze in place.
An instant later, the 12-car freight train plowed through.
It passed by with tremendous speed while just barely grazing Kamijou’s clothes.

Suddenly, a male voice spoke from the slight space between the bottom of the train and the ground.
“Hey.”
“Thor!!!???”
All of Kamijou’s hair stood on end. He had not been trying to kill Thor, but there was nothing else he could do if the boy could get up after that. That surprise attack would not work a second time.
Thor was covered in blood, but he appeared to be in one piece.
[…]
He may have switched out his “target” at the last second, avoided a direct hit, and “fled” under the train.
