《Touhou Tag Dream(夢の東方タッグ)》 is a 4koma series on Danbooru and Pixiv based heavily on Kinnikuman(キン肉マン), and thus is centered around a tag wrestling tournament. It is one of the longest running Touhou 4komas ever, with currently just over a thousand strips.
@wolffenrirhelix Well, in 輝夜(Kaguya)'s self introduction, she said: "I'm a Touhou-holic. Flandre-chan is my sister, Mokou-tan is my lover, and Reisen is shimapan(striped underwear)."
