The next moment, Shinichi raised his hand.
"Whoosh!"
The crimson flame in his palm shot forward at his command. The instant it left his hand, it didn't swell or disperse. Instead, freed from the constraints of rotation, it took on a smoother shape, like a crimson arrow of fire tearing through the cold air with a sharp whistle!
Halfway to its destination, the highly condensed Chakra structure within the fiery arrow seemed to reach some kind of critical point and suddenly released.
