sorry pestering you and purvis, kilga, OTLOne interesting thing that I primarily thought of thanks to other TL people on Warosu and the Touhou Wiki (GenoCraft, Nazohato, etc.) is just what sort of focus the story might have thanks to the characters used in the title.
Suika is the most obviously-teased character for this manga; that is very clearly her wristband and gourd in the right panel looking all ominous, and 酔華 (sui ka) is right there in the title, and all the uses of terms relating to drunkeness also being a lead factor helps.
It should be noted that "
Lotus-Eaters" (hyphen included) were actual people in Greek mythology that, given the description of living in a sort of narcotic tranquility thanks to the literal influence of lotus plants, may be a parallel to Touhou's Heaven, given the constantly-indulgent "song-and-dance" lifestyle that is lead by the Celestials, as described by Suika in SWR, especially when one considers the meaning/uses of lotus flowers in Buddhism.
Maybe I may just be pulling at straws for now and Gilde or Clarste or Nietz or whomever can explain in more concise ways what we are looking at, but it seems like this story could go anywhere from what I can see.
