A graduation commemorative work for Kanae Ruka!! Ru-tan, who ran through our youth of creampies together with us, is graduating!! Before we knew it, the angel Ru-chan, who always gave us smiles and creampies, ended up with a big gathering of her friends!! If she gets caught while chasing someone on the crawl, she'll be creampied! If she gets creampied 20 times, she can't retire!? The impregnation team, who want to stop her retirement, and the protection team, who want to let her retire, clash over Ru-tan's retirement!! In the moving finale, a tearful final message. Everyone loves Ru-tan!!
