The surging strength that arose within Seiya's body helped him ignore the worn down state his body was in.
The Aspect of the Moon had affected his very state and it gave him the push needed to continue this battle which his sister couldn't decide whether or not it was going to change much or if it'll end the same.
His speed spiked, appearing as an afterimage on the very spot he stood.
Kami noticed his speed and wondered where he may be but her educated guess was that he'd try once more to strike her on her face and so her next action was decided.
She'd swat at the area in front of her face and without seeing Seiya, she could feel a small weight in the air as he materialized.
Seiya's glowing form appeared in the air in front of Kami's face, his speed stopped by Kami's palm but unlike before his strength was potent enough to resist the palm's strength which forced Kami to use his other hand as well.
