Leatherback could feel the rise of the ocean floor. They would be there soon. Otachi looked down at him and smiled. They both had a new trick up their sleeve to deal with this city. Leatherback slammed his fists into the ground in excitement. Otachi began to wonder if they still had those giant metal things that warded them off last time. Both her and Leatherback had to lay dormant for a while after that.
The thought only angered her more. She wanted to rip that metal thing apart! Her thoughts subsided when she looked up to see the surface of the water. Otachi looked down at leather back and nodded.
"You know what to do."
Leatherback nodded in return as they both transformed into their more humanoid form. Otachi stopped swimming to think about where they should enter the city. She hated these weak, squishy forms. Leatherback just sat there and stared at Otachi, admiring her new form. Otachi looked back at, catching him in the act. She laughed, "Come on."
They both swam closer to a dock structure Otachi spotted. They poked their heads out of the water only to see a human standing in front of them. Luckily his back was turned. Otachi smiled as she lifted her tail out of the water. With one swift action, she grabbed the human's head with her tail and dragged him in the water. She squeezed the pincers until she felt the bone collapse. 
The female kaiju disposed of the body and they both climbed up onto the dock. Leatherback noticed that he looked more human than Otachi did, and that bothered him. She could be spotted more easily. He looked around and noticed a cloth covering some crates. Grabbing the cloth, he wrapped it around Otachi. Taking the hint, Otachi curled her tail around herself to hide it. She leaned over and pecked the kaiju on the cheek and began to walk towards the city. Leatherback blushed and quickly followed.
