"hi .I'm Nana Nishigaki from Yuru Yuri. it's a pleasure to meet you! I'm fan of Nickola Tesla from record of ragnarok. I'm assistant of yoshino FEYNMAN." *She lives a mile from school and commutes by bicycle, but for some reason she wears a full-face helmet. She also experiments at home, such as failing to fly in the air with a cannon and blowing off the roof of the house due to the impact of the launch.

Nana first displayed her prankster powers when she made up a story about how she became interested in science, involving a toy robotic puppy which stopped working. It is later revealed that the real reason is when she accidentally plugged a miniature light bulb into a main wall socket, causing it to explode as a student.*
