Valentine Kiss is a solo debut album by Sayuri Kokusho first released in 1986. In 2004, 18 years later, a popular character named Keigo Atobe from the anime Prince of Tennis sang Valentine Kiss as his character song single.
Soon after, the character posed and wore clothing just like the CD cover on Sayuri Kokusho's Valentine Kiss and numerous parodies were inspired by it. Since then, every Valentine's Day have had new additions to the Valentine Kiss parody meme.
Even on pixiv, many of these new additions were uploaded! Today's Spotlight is about characters from Prince of Tennis and characters who aren't from the series parodying Valentine Kiss!
