LoveLive! Series 9th Anniversary Love Live! Fest
Love Live! Fest was an event of many firsts – it was the first Love Live! concert to feature multiple groups across different projects, it was the first time Love Live! announced a cast audition open to the general public (in which several members of Liella! and Hasunosora would eventually participate), and, of course, it was the first time μ’s performed on stage in nearly four years.
