Perisai Jitu is known as the third original song by Moona Hoshinova, a virtual idol with Hololive Indonesia under Cover Corporation. The title is Indonesian, reflecting Moona's identity as an Indonesian VTuber and her connection with her audience, who often share her music in fan edits and short clips. Because the track is tied directly to her idol persona rather than a game or anime series, it circulates mainly within the Hololive community. Fans keep returning to it as a recognisable piece of her discography and a shorthand for her cheerful, supportive stage presence.
