>>2800204As a personal opinion i could consider that ON STAGE (2020) is her best album since despite being the last, some songs have become emblematic and others are simply good:
guruguru love story- currently her signature dance song, she has danced it to most major concerts (parallel time/beyond fest/v-carnival)
Step and Go - maybe Sora's favorite, appears frequently in utawakus, should be mentioned that she chose it for karaoke in her debut of the new 3D outfit and also chose it for the radio show recently
Chu-Chu-Lu- quite a romantic song, she has mentioned that is very popular among the kaigai niki
REA / REMO sympathizer- highly underrated song
make mention of "Sora matsuri (festival)" and "Maiodore Time" which are not bad songs but in the case of the latter i am not much of a fan of Miko...
