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. However, Niko accidentally forgot about her lie, and ends up cooking for everyone, where the truth is revealed.

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.

In episode 10, Niko is shown to be a very skilled cook despite saying she never cook before.

Chronology
Yazawa Niko first appears in [http://love-live.wikia.com/wiki/Come_True!_Our_Dreams! episode 1] in a 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 towards 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 her school.

Niko doesn't appear until episode 5 when she confronts Honoka and Kotori to tell 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, since they have enough members to form a 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 her belief in μ's being inexperienced idols because of their lack of personas, Niko says no again and locks them out.

The school's vice-president Toujou Nozomi explains to μ's that Niko once attempted to become a school idol, but failed because one by one her group's members quit because Niko set the bar too high for them. After some thinking, Honoka comes 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 of μ's. However, it 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 still believed 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.
