Her signature ability is releasing pent-up frustration through aggressive death metal karaoke sessions, which serves as both an emotional outlet and a plot device throughout the series.

Notable catchphrases include her passionate exclamations during karaoke, symbolizing her inner rebellion against societal expectations.

Retsuko’s standout skill is her vocal talent, particularly when it comes to death metal—a genre she uses as a way to vent her emotions.
