Yea, a standard terrain. Well, I would RP, but the scenario you put is..xD
Hashirama took an offensive stance as dark clouds gathered in the sky and it started raining soon. Rain would hinder his movements. Kneading a large amount of chakra, he weaved a single handseal and exhaled the gathered chakra in the form of a super powerful blast of wind at the clouds, thus pushing them away and dispersing them eventually, stopping the rain. Wiping off some water off his armor and legs, he focused his attention back on the girl. Purplish hair and dark skin. She looked charming. However, Hashirama was totally unfazed by this. Weaving a string of quick handseals, he placed his hands forward, with fingers curled. Utilizing a large amount of Lightning chakra, he manipulated it so as a blinding bright light appeared from his body and blinded her. As she was suddenly taken aback by the sudden blinding light, he weaved a single handseal, creating a world of infinite darkness, trapping her within the illusion. He then threw an explosive kunai aimed at her head.

Description: After performing the following handseals Ram → Horse → Snake → Tiger the user will release a massive amount of lighting chakra which he uses to create a blinding light that appears to emanate from all over the users body.
