While the anime’s ED movie features its main heroine Ristarte’s CG dance, Riko Azuna, the singer of the ED theme song “be perfect,plz!” for the fall 2019 TV anime Cautious Hero: The Hero Is Overpowered but Overly Cautious, has posted a 100-second clip to introduce her own dance performance with the song.
The 25-year-old singer-songwriter started her singer activities when she was in university, then made her major debut from KADOKAWA with “Kimi ni Furete” (TV anime Bloom Into You OP) in November 2018.
She has provided the theme/insert songs for Re:Zero − Starting Life in Another World Memory Snow, Boogiepop and Others, and Astra Lost in Space.
