Mizukage: So that's Susanoo. I'll be sure to watch you closely.
As some of my water begins to fall on your Susanoo, I feel the ground cracking and rumble slightly around me while kunai are headed towards me. Since my water tech can stop in a instant I do so while preforming the snake seal and making my skin like steel. By doing this the two spikes rise up and break against my skin while the kunai hit me as well and bounce off.

Immediately following that I see my lava drying around you so I release my chakra into the ground and cause vapor to rise up around you from the ground and cause corrosive explosions hitting all three of you, to destroy your clones and make you handicap.

Then as Mei's vapor is exploding around you and burning you severely and more than likely causing you to be thrown you off, Mei by sticking with her Boil chakra preforms the tiger seal and spews out a large amount of vapor to cover the whole area to begin and melt everything, this is done as a precaution because she's seen your Susanoo and hoping to melt it with you along with it, done with the fullest PH level possible since no allies are around and I'm immune to the effects as stated in the description.

Mizukage: Sometimes it's fun to melt those who cause me distress.
