I saw her at Zepp Tokyo the other night as part of her fanclub tour, loved her! The set was very cute, there was a staircase leading up to three different rooms.
The only a-sides she sang were Darling, Torisetsu, and maybe Suki (I forget
). She ended with "Together" which was a nice ending. During the encore, the audience sang the chorus of Rainbow, singing "Kana" instead of "Kimi"
She did a medley of her more dance/upbeat album tracks/b-sides, YES for Shut Up
Personal highlights were missing you, One Way Love, No.1, Unzari, A-Gata no Uta. It was one of the better setlists of the concerts I've been to in Japan! She forgot the lyrics at one point near the beginning of missing you, so started the song again, haha. Cute!
Hopefully I can go to her arena tour later this year too
