I think I have grown out of their first three A-side singles. Nowadays I prefer Kimi ga Inai, Kataru nara mirai wo and Otona wa Shinjite kurenai. They are early era songs but not the songs they pushed over Saimajo, Sekai and Futari Saison. When I got into Keyaki I thought nothing beats Saimajo, Sekai and Futari Saison but I was wrong as soon as the first album came out I preferred their dramatic side like Getsuyoubi no Asa skirt and Kimi wo mou sagasanai. Techi's solo song, Jibun no Hitsugi, was even better than PARCO, and performed live it was a shock. Go back to 2017 it's a big contrast between 1st Birthday Live, Keyaki Republic and Zenkoku arena tour final. You can see they still have a traditional idol group style from 2016 at Republic. However, the album made things changed for their album tour. Fukyouwaon was a game changer for Keyaki, that single alone put more bold songs on the A-side for future singles. You could dare to say it helped Keyaki to find their image to step away from safe cards in 2016. I'm one of those who prefer Hiraishin over Kaze ni fukarete mo and Moumori e kaerou ka? over Garasu wo Ware!. Ambivalent was the first single to go full dark with senbatsu songs from Kanji. I'm glad they performed all senbatsu songs from Ambivalent single at Budokan. I'm out and Student Dance are very underrated gems. Fukyouwaon is not the best as studio version but performed live is indescribable.
