Voice: Medium-High
In Episode 5, it is discovered that during her first year in high school she started an idol group. However, one by one the members gave up because Nico's goal to become an idol was too much for them and they couldn't keep up.
Normally, Nico has quite an aggressive personality, but when she takes on her alternate personality she becomes a happy, upbeat character who is always smiling. Her catchphrase is "Nico Nico Nii!" accompanied with a pose. She often thinks a bit highly of herself but despite that, she is also caring.
