For there to be an absence of shadows of ANY sort. There must either be absolute darkness. OR there must be an equal amount of light be shone from every single angle.
For the intents and purposes of this match:
They are in a field covered by clouds. They are now in a large shadow. Kage Mane can be used to trap an opponent instantly since the shadows are inter-connected. To prove that Hasashi's shadow is separate from the cloud's shadow, I say this:
the entire country is not the entire country is covered by an equal amount of clouds. Light flows through at different intensities as to create patches on the earth. These patches pass over the ninja on the ground with the natural movement and flow of the clouds in the air. There will be a slight shadow because light passes through clouds but cannot pass through a human. Therefore a faint outline of Hasashi CAN be found on the earth. everything is in shadow, Hasahi has a shadow that is distinct from that of the clouds and SN use Kage Mane. The Kage Mane had trapped hasashi as soon as SN cast the jutsu.
It is over.
he thought by blocking the sun that it was preventing me from using shadows, but it actually helped me out more
