Touhou Christmas 2015! (東方クリスマス２０１５！, Tōhō Kurisumasu 2015!) is the fourth Cookie☆ voice drama by “Ako Atouda” that was uploaded on December 10, 2015.¹⁾ The video's short name is KusoKuri☆ (クソクリ☆), but was previously Kusso☆FINAL (クッソー☆FINAL).²⁾

It starts off with Marisa (Ruka) telling Reimu telling that she plans to returning junk that she stole in the spirit of Christmas. Reimu finds Marisa (Kohaku) who breaks the fourth wall and explains why Marisa (Ruka) left. First, they break into Alice's house to return a doll while Alice moans about mushrooms. Reimu brings up the newer Touhou Project characters, but Marisa stops her as the intended audience won't recognize them

They meet Eirin next to return the medicine that was stolen in Cookie☆☆ S1. Marisa (Kohaku) is called to a party, so Marisa (Akane) meets Reimu and they return a cookbook to Rurima who audibly regrets being in Kusso☆☆☆. The video cuts to a very brief hot spring scene, then they move on and return the Dark Inferno to the original character from Memo☆, Miramikaru Riran.

Marisa (Akane) had to leave as her mother told her to sleep, so Marisa (Yuuhi) and Marisa (Meguru) get to tag along with Reimu next. They run into a peculiar cat, then move onto Rinnosuke's house who was given the aforementioned medicine. He was being creepy to Reimu's voice actress, so the Marisas deliver a Master Spark. The Marisas leave for Karaoke as they finished returning everything, leaving Reimu by herself.

As she returns home, Marisa (Kohaku) comes back since the party wasn't worth it and talks about how she'd rather spend Christmas drinking sake with Reimu. The video ends panning towards the moon, showing what other Marisas are doing, and the credits roll. After the credits, there's a bonus scene that has Reimu singing “Jingle Bells” with the five Marisas.

• Reddit uses “Kusso☆☆☆☆” (クッソー☆☆☆☆), but Kusso☆ S4 (クッソー☆4期) works better.
  • There is no sokuon in “KusoKuri☆” (クソクリ☆), so it cannot be read as “KussoKuri☆”.
• The entire video is a Cookie☆☆ S1 parody that has many references to Cookie☆ in general and it even satirizes the meta. Some may love it for this, others may not. Compare with Kuso★.
• If it isn't obvious, most of the character designs are recycled from previous voice drama projects:
  1. SRMY姉貴 borrows design elements from BNKRG姉貴 (Cookie☆☆ S2).
  2. RK姉貴 borrows design elements from RI姉貴 (Cookie☆☆ S3) and KG姉貴 (Kasu☆).
  3. KHK兄貴 borrows design elements from MZ姉貴 (Cookie☆☆ S2).
  4. AKN姉貴 borrows design elements from RI姉貴 (Cookie☆☆ S3).
  5. YUH姉貴 borrows design elements from UDK姉貴 (Cookie☆).
  6. MGR姉貴 borrows design elements from ASZ姉貴 (Cookie☆☆ S1).
• “Tamago Sushi-kun” (玉子寿司くん, lit. “Egg Sushi”) from Memo☆ also makes a cameo with Riran.
