Who knew that heavy metal influences would go so well with a magical girl anime?
And lo, I looked upon episode 25 of Heartcatch Pretty Cure, and in the second ED, they didst make a gospel song! And lo, it was called Song of Tomorrow, and it was awesome! Hallelujah!
On the non-Leitmotif end of things, there's also Pretty Cure no Shimei wo Mune ni, which pulls double duty as Cure Beat's unofficial theme song during her first few appearances.
Beat of Fierce Fight. Seriously! All of these Heavy Metal songs truly blur the line between Shoujo and Shōnen soundtracks. This one is no exception, and it really drives the point home.
Yayoi Kise's character song, 100% Hero shows off what an Ascended Fangirl she is; if it had deeper, male lyrics, you'd swear it was the opening to a Tokusatsu show!
