Anharu

Anharu is the femslash ship between An Shiraishi and Haruka Kiritani from the Project SEKAI fandom

Canon
An and Haruka had been childhood friends ever since elementary school. Although An goes to Kamiyama High and Haruka goes to Miyamasuzaka, they still hang out with each other outside of school. Both were experienced in the idol career before joining their respective units, An was a popular performer at her father's cafe, WEEKEND GARAGE, and Haruka formerly a member of the idol group ASRUN, being the member with the highest popularity. An appears in both side stories of one of Haruka's three-star card and Haruka appears to be talking with An in the Vivid BAD SQUAD event, Singing in Sync. They also have one area conversation together.

In the first side story of Haruka's 3* card "The Non-Idol Me", Haruka ends up going to visit An at the WEEKEND GARAGE. They go sit down to talk to each other after not seeing each other since middle school.

Fanon
Anharu isn't a very popular ship within the fandom due to An having way more popular ships with others. They mostly are rivaled by Anhane and Minoharu. People mainly prefer them as a platonic relationship and have one be a wingwoman for the other. They are mainly shipped beside Kohamino.
