I can't tell if this a prime example of good Tuning or they just layered the original singers during the slow parts.
But seriously go watch "My next life as a Villainess". I don't really enjoy isekai shows with the exeption for .hack//root, and that came out years ago, much less romance otome and harem . But I recently binge watched this gem until the recent episode last week. It's really fun, especially the chaotic Antagonist-turned-Protagonist aka the Black Hole "Bakarina".
Still waiting for IA to cover the Kaguya-sama op. I find it fitting since the mangaka, Akasaka Aka, designed her. IA was even referenced in the manga.
