Chronology
Rin is first seen in [http://love-live.wikia.com/wiki/Come_True!_Our_Dreams! episode 1] when following Hanayo to see A-Rise perform on a screen at UTX. Later, Hanayo wanted to go to see μ's concert, but Rin grabs Hanayo and tells her she wants to join the track club. However, being too shy to say no, Hanayo is forced to go with Rin. Luckily, Hanayo manages to get away from Rin and manages to watch μ's perform. Rin finds Hanayo but is quickly distracted by μ's performing Start:Dash!

In Episode 4, Hanayo wants to join μ's but also want Rin to join with her. Rin, however, says that she doesn't want to join the group, because she isn't confident in her femininity. Later on, Rin and Nishikino Maki fight over who can help Hanayo, and Hanayo is caught between them. Near the end of the episode, with a push from Rin and Maki, Hanayo manages to confess that she wants to join μ's. μ's accept the offer, and Rin and Maki decide to join as well, thus making μ's has six members.

In Episode 5, a girl name Niko tells μ's to break up and runs away. While on the rooftop, the girls know that it's the rainy season, but Rin and Honoka go outside anyway, and end up getting soaked by the rain. While at a fast-food restaurant, Honoka realizes that there are enough members to form a club. Just then, they catch Niko trying to steal their food and insult their lack of professionalism. The girls learn from Ayase Eri, the student body president, that they can't form their idol club as their is already an Idol Research Club, whose sole member turns out to be Niko. After Niko rejects their offer of merging the groups, presumably based on their lack of personas, student body vice-president Toujou Nozomi explains how Niko had previously attempted to become a school idol but set the bar too high, leading it to fall apart. After some thinking, Honoka comes up with the idea that they should all join the Idol Research Club to learn how to improve μ's, inviting Niko to join the group as their coach. Happily, Niko accepts the offer.

In Episode 6, Nozomi was recording interviews of each member of μ's, until she came to Honoka and asked her why she was the leader when she did nothing. Niko then comes up with the idea to have a karaoke and dance contest, and the one with the highest score would be the leader (although, secretly, Niko was planning on getting the highest score). Unfortunately, all the girls get similar scores. Honoka then suggests that maybe μ's doesn't need a leader. Everyone agrees with her, although they believed that she was the most worthy (except Niko, of course).

In Episode 7, Hanayo tells μ's about the Love Live, a concert where the top 20 school idol groups compete in. The girls then go over to the chairwoman to ask permission to be able to enter the Love Live. Despite Eri's objection, the chairwoman allows them to enter, but only if they all pass the upcoming exams. The members that need to study the most is Honoka, Rin, and Niko, who presumably have bad grades. Sonoda Umi and Minami Kotori helps Honoka study, while Hanayo and Maki help Rin, and Nozomi with Niko. Once the exams finished and everyone passed the exams, μ's excitingly go to Chairwoman Minami's office, but overhear her telling Eri that the school would be shutting down next year.

In Episode 8, μ's barge into her office, demanding an explanation. She clarifies to them that if the school's upcoming open day doesn't go well, the school will be closed. While Eri tries to think of a way to attract students, Umi suggests to μ's that Eri should be their choreographer. Eri soon agrees and puts the group through intense training. Later on, Nozomi informs μ's that Eri wants to join, but believes she can't because of the way she used to treat them. The group then asks her to join μ's. Eri becomes honest with herself and feelings, and joins μ's with Nozomi. Nozomi then reveals to the group that she came up with the name; μ's meaning the nine goddesses of music. The now nine members of μ's performs at the open day and successfully pleases them.

In Episode 9, Eri assigned Kotori to write lyrics for a new song based on Akiba culture, because she works at a maid café there. Kotori, unfortunately, struggles to create the lyrics, which soon has an impact on her studies because of her stress. However, thanks to Honoka and Umi, she is able to create the song Wonder Zone by recalling her feelings when she works in Akihabara.

In Episode 10, μ's get permission to go to Maki's beach house to supposedly train. Eri, wanting to break the barrier between under and upperclassmen, makes a rule that no one is to call their upperclassmen with the honorifics 'senpai'. For most of the time there, the girls spend time on the beach, playing (although Umi was planning on making the beach trip a training session), and Eri and Nozomi are the only ones that notice Maki isn't participating. When the girls were going to sleep, Honoka says that she couldn't sleep and began eating food. Nozomi soon starts a pillow fight and the rest of μ's (excluding Umi) have a pillow fight with each other. Accidentally, a pillow hits Umi and, crankily, Umi began throwing "supersonic pillows". Umi hits Niko, Eri, and Honoka, and was about to attack Rin and Hanayo, when Maki knocks her out with a pillow, saving everyone from Umi's rage. The next morning, when the sun was rising, all the members of μ's go outside to the beach and hold hands with each other.

In Episode 11, μ's manages to make it to rank #19, making them eligible to apply for the Love Live! This puts pressure on μ's to work extra hard to keep their rank. However, things don't go their way when they are unable to secure a spot on the auditorium for the upcoming school festival, thanks to Niko failing a lottery spin.

Honoka suggests to the group that they could instead hold their performance on the school rooftop where they train. The other members are slightly hesitant to this idea, but agree. While warming up on the rooftop, Umi told Honoka that she shouldn't be working herself too hard, but Honoka said that it's all right. When Umi asked Kotori to tell Honoka to stop, Kotori didn't respond because she was thinking about the letter she received in episode 9. After Umi snapped Kotori out of her daze, Kotori said that Honoka should do whatever she want, disappointing Umi and making Honoka happy.

Later on, during a phone call, Umi asks Honoka if she ever noticed Kotori acting weird. When Honoka said that she didn't, Umi told her to go straight to bed instead of exercising, then called Kotori. Regardless of her order, Honoka goes out to jog in the rain. Because of this decision, Honoka awakens feeling dizzy, but goes to school, anyway. After performing No Brand Girls, Honoka faints from overworking herself, and all of μ's are shown worried.

In Episode 12, μ's go to Honoka's house to check on her. They discover that she's still recovering and has a sprained leg. They sadly tell Honoka that they dropped out of the Love Live! tournament, meaning their ranking was removed. Honoka blames herself for the incident, but μ's tell her that it's everyone's fault, instead. Everyone gets depressed from this event, but Honoka the most. At the rooftop, Maki, Hanayo, and Rin all announce that the school has been saved, thus the group decides to have a celebration. At the party, however, Umi and Kotori are noticed to not be in jolly spirits. Umi then reveals to μ's that Kotori is moving to a fashion boarding school for the rest of her high school career. Everyone is surprised by the announcement, but Honoka gets angry at Kotori for not telling her earlier. Kotori explains to her that she wanted to tell them but couldn't, and runs away.

The next day, on the rooftop, μ's reveals that they're planning to do a final live with everybody before Kotori leaves. But Honoka tells them that it was her fault and that none of this would've happened if it wasn't for the accident. The members tell her to stop saying that, but Honoka then says that the school is saved, therefore there's no reason to keep on performing and that's it's impossible to go against a group like A-Rise. Honoka tells them that she quits, but before she leaves, Umi slaps her cheek, saying that she didn't think that she's that kind of person and that she's the worst there is.
