Naori looked at the ball of lightning, and beyond surprise, something else flickered in her eyes.
She blinked her eyes, which had returned to black, as though she were considering something.
"But this technique still has a problem," Mirai said candidly as he dispersed the lightning in his palm.
"Chidori requires an extremely fast charging speed when it's unleashed, but an ordinary ninja's dynamic vision can't keep up.
"If the distance is too great or the opponent moves fast enough, it's easy to miss."
