YouRiko

Youriko is the femslash ship between You Watanabe and Riko Sakurauchi from the Love Live! fandom.

Canon
At the beginning of the show, You Watanabe and Chika Takami decide to become school idols together, and soon after meet Riko Sakurauchi and convince her to join them. From then on, they spend time together, oftentimes alongside Chika. They are also occasionally seen hanging out or sitting alone.

As the two girls are both first years, they naturally become closer to each other than with most other girls in Aquors. Riko occasionally teases You and compliments her. While Riko is away at her piano performance, she calls You on the phone. You confides in her that she feels Chika is happier spending time with Riko than with herself and cries. Riko assures her that this is not the case.

In Love Live! Sunshine!! The School Idol Movie: Over the Rainbow, You's cousin visits. Upon meeting all of Aquors, she immediately recognizes Riko and tells her that You talks about her constantly and looks up to her. She blushes at this. Later, when Mari tells You's cousin that she is beatiful, Riko teases You, saying that of course she was pretty, as she's related to You.

Fanon
These girls are often shipped due to their conflicting yet complimenting personalities- Riko is very shy, artistic, and traditionally feminine, while You is more outgoing, sporty, and tomboyish. They are also shipped because of their friendship. Youriko is often rivalled by YouChika and Chikariko, as both of the girls are slightly closer to their mutual friend.

This ship originally started before the show was finished as a crack ship, yet has gained popularity in recent years.
