Mariko Nakamura

Mariko Nakamura is a friend of Suzy Mizuno as they both attend the same clubs together at Mochinoki Middle School and Suzy in the Japanese version calls her "Mari-chan".

Mariko, however, is seen to be more conceded and obsessed with her appearance than Suzume tends to be, her importance, along with Kiyo's other friends' importance's develops as the story progresses. She also has great cooking skills and is skilled in ping pong, even though Gash and Kiyomaro managed to beat her.
