Nico Yazawa

Yazawa Niko is one of the nine main characters in Love Live! She is 17 and third year in high school despite how she looks. Her main color is pink. Niko was born on July 22nd and is a Cancer. Niko is 154 centimeters tall, and her blood type is A. Niko is voiced by Sora Tokui.

Background
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 Niko's goal to become an idol was too much for them and they couldn't keep up.

Personality
Normally Niko has quite an aggressive personality, but when she takes on her alternate personality she becomes a happy, upbeat character who is always smiling.

A common joke in the series is that she's often ignored by the members μ's at her attempts at being the better idol. An example at an attempt is in [http://love-live.wikia.com/wiki/No_Upperclassmen_Allowed! episode 10] when Niko claims that she has a personal chef like Maki, and Kotori falls for the lie unknowingly.

Clubs and Hobbies
Yazawa Niko is the Idol Research club president and is interested in fashion, therefore she designs the group's outfits with Kotori.

Chronology
Yazawa Niko first appears in episode 1 in her noticeable disguise that consisted of a scarf and glasses. Niko was at UTX when Kousaka Honoka appears, watching A-Rise perform on a screen. Because of NIko's first attempt at becoming an idol failed, Niko showed resentment at A-Rise. Not knowing who they were, Honoka asked Niko who the group on the screen were. Shocked, Niko explains to her that it's A-Rise, a school idol group, and that UTX was getting a lot of students because of their fame. At that moment, Honoka got the idea to form a school idol group to save the school.

Niko doesn't appear until episode 5 when she confronts Honoka and Kotori and tells them to break up μ's. Later on, Niko meets the rest of μ's who ask her to end her Idol Research Club so they can create a School Idol Club. Niko flat out refuses and tries to run away but fails because of her lack of stamina and Hoshizora Rin catching her. Still remaining stubborn and jealous (and because of the group's lack of personas), Niko says no again and locks them out.

Vice-president Toujou Nozomi explains to μ's that Niko once attempted to become a school idol, but failed because one by one her idol group's members quit because Niko set the bar too high for them. After some thinking, Honoka came up with the idea to join Niko's Idol Research Club to ask Niko to teach them how to improve μ's. Happily, Niko accepts.

In the next episode Nozomi was recording interviews with  μ's until she asked Honoka why she is the leader when she does nothing. Niko then suggests to have a karaoke and dance contest to determine the leader. Secretly, her plan was to outshine everyone else, which would then make her the leader. But backfires when everyone gets similar scores. Honoka then brought up the idea that μ's doesn't need a leader and everyone agrees (although everyone except Niko believe that Honoka should've been the leader).

In episode 7 Minami Kotori's mother, the chairwoman, tells the group that if they don't pass the exams, they won't get to perform in the Love Live! tournament. Needing the school's permission to go, this puts pressure on Honoka, Rin, and Niko. Luckily, all the members pass the exams. However, when they were about to tell the chairwoman, they overhear her telling Ayase Eri that the school will stop accepting students and shut down next year.
