Yazawa, Niko

矢澤にこ

Niko typically displays a rather aggressive personality, yet when she adopts her alternate persona, she transforms into a cheerful, upbeat character who is constantly smiling. Her signature catchphrase is "Nico Nico Nii!", which she delivers alongside a specific pose. She tends to think somewhat highly of herself, but even so, she remains caring.
A recurring joke in the series is that the other members of μs frequently ignore her attempts to prove she is the best idol among them. Niko often becomes annoyed with the former student council president, Ayase Eli, because Eli steals the spotlight from her with her beauty and maturity.
Niko served as the president of the Idol Research Club until her graduation. In Episode 10, she is revealed to be a very skilled cook, despite having claimed she had never cooked before. However, she accidentally forgot about her lie when dinner time arrived, and ended up cooking for everyone, thereby revealing the truth. Niko is also interested in fashion.
