Every year, lotteries are organized for the Hello! Project's Hina Fest concerts, in order to create special units and above all, to determine which members will be assigned a solo performance in the great hall of the Makuhari Messe. Reina having become a member of Morning Musume. at the end of 2016, Hello! Project Hina Fes 2017 is the first Hina Fest concert in which she participated. Nevertheless she will have the chance to pull one of the four papers allowing her to perform a solo performance, which took place on March 26, 2017 ! A few songs were advised to staff members. It was then Kudo Haruka who pressed "Haru Beautiful Everyday", since spring was coming. Reina agreed to perform this song, which as she said, suits her perfectly. This performance can be found on the "°C-ute Premium" CD of the DVD concert.
Reina en a parlé sur son blog le soir-même : "A few months ago, I never thought I could perform on such a big stage. There were so many people in the audience ! Reina has her heart completely filled. About my solo performance, I sang 'Haru Beautiful Everyday". I was so nervous before the performance that I cried. Lol. First, it was the first time on such a huge stage, then, I sang alone ... But all of my senpai reassured me a lot, by saying "smile and have fun!". This is what I do and it went well. But ... sing alone ... It's so fun ! I want to do it again as soon as possible !! There were a lot of yellow penlight ! I'm so happy ~"
