Plenty of Grit

Slayers Revolution marked the return of the Slayers franchise to television anime after an 11-year hiatus since the conclusion of Try in 1997.^[5] Hayashibara, the voice actress for the protagonist Lina Inverse since the original series, reprised her role and was also deeply involved in the production and direction of the theme songs for the new series, drawing on her extensive knowledge of the franchise.^[6] For the opening theme "Plenty of grit", Hayashibara aimed to recreate the atmosphere of the earlier television series entries, and there aimed to regroup the original contributors of theme songs from the original 1990s series, which she aimed would serve as a nostalgic "tease" for longtime fans familiar with the old staff.^[6] She selected a composition by Hidetoshi Sato from nearly ten demo tapes, specifically choosing one where the intro prominently featured the word "Slayers" in a recognizable manner. The arrangement was handled by Tsutomu Ohira, who had previously worked on Slayers Next, while Masami Okui contributed with backing vocals.^[6] The anime began airing July 2, 2008, on TV Tokyo.^[7]

The lyrics of "Plenty of Grit" reflect themes of perseverance, the inherent value of life despite setbacks, and inner strength.^[6] Hayashibara explained that both "Plenty of Grit" and "Revolution" address universal human experiences—doubt, discouragement, the desire to give up or curse one's circumstances—while affirming that life begins as a "win" simply by being born against incredible odds.^[6] Additionally, she expressed a desire to return the resilience and "grit" she had learned from the early years of Slayers, channeling it back into the franchise through the songs.^[6]

The CD single was released on July 23, 2008, following the June 2008 release of Slayers Megumix, a 29-track compilation album of Slayers-related songs curated by Hayashibara herself.^[7] Both "Plenty of Grit" and "Revolution" were later included on Hayashibara's fifteenth studio album Choice, released on July 21, 2010.^[8] "Plenty of grit" was also featured on Hayashibara's best-of album Vintage White, released on June 11, 2011.^[9]

Although it is treated as a double A-side ("Plenty of Grit/Revolution") in Oricon listings, on the Hayashibara's official site, as well as in promotional materials, advertisements, and other related sources, the single is actually listed a single A-side featuring "Plenty of grit" alone.^[10]

"Plenty of Grit" debuted and peaked at number 6 on the Oricon charts,^[11] selling 14,940 copies on its first week.^[12] The single charted for nine weeks in total, with reported sales amounting to 25,931 copies.^[12]
