The Melancholy of Marisa Kirisame (霧雨魔理沙の憂鬱, Kirisame Marisa no Yūutsu) is the 8th track of Silver Forest's¹⁾ doujin album, Touhou Sougentou (東方蒼幻燈), which was distributed at Comiket 71 on December 31, 2006.

It starts with Marisa needing to pee and stopping in the middle of the forest, but she is stopped by Alice who had been looking for Reimu. While she gets flusters and tries to run, Alice holds her hostage and theorizes that she was going to masturbate or have sex with Reimu, so Alice submissively offers herself to Marisa. After a certain amount of time, it's implied that Marisa couldn't hold it in any longer and urinates.

For the Cookie☆ community, this voice drama is known as the “The Grandfather of Cookie☆” (クッキー☆の祖父, Kukkī☆ no Sofu) as it's commonly believed that the unofficial Niconico Douga upload²⁾ would later inspire Hazuna Rio to create the Author is Healthy Series videos, which eventually led to the infamous Marisa and Alice's Cookie Kiss☆ video and the subsequent scandal.³⁾

• It should not be confused with Kurage no Bone's karaoke assortment CD, The Melancholy of Marisa Kirisame, that was distributed at Comiket 76 around August 14, 2009.
