Nishiura's Cheer Girls act as support for Nishiura baseball team during their games. Ayano Tomoi and Mia Ogawa are the founding members who asked Shino'oka for Hamada's permission to be part of the cheering team.
They were supposed to debut on Nishiura's game against Sakitama but instead, debuted on Nishiura's game against Kounan High School.
They wear no-sleeve white uniform with red stripes and red short skirts. The logo Nishiura (red-colored) is at the center of the uniform. Initially, they wear below-the-knee socks as well but they do not wear socks during their support on Nishiura's game against Bijōdaisayama.
