My take on Touhou story "arcs"

[Failure McFailFace]

Mostly just grouping the games together into semi-coherent overarching story lines:

Gensyoko gets invaded by other dimensions (PC-98)

• HRtP: Either Makai or Hell
• SoEW: Reimaden
• PoDD: The Outside World (but only 2 people)
• LLS: Dream World
• MS: Makai

Era of 1 game = 1 unrelated story

• EoSD: Red mist caused by vampire
• PCB: Winter extended by ghost, powerful being too lazy to fix border
• IaMP: Oni mist
• IN: Lengthened night by moon people to keep moon people out??? (Complicated plot? Lunarians)
• PoFV: Deaths in outside

It was a Moriya Shrine Conspiracy

• MoF: Introduction
• SA: Kanako gives raven a god to eat, makes geyser
• UFO: SA Geyser releases boat

It was a Moriya Shrine Conspiracy 2: Religious War

• TD: UFO ship resurrects Taoist person
• HM: Popularity Contest

Amanojaku Shenanigans

• DDC: Amanojaku gives midget mallet
• ISC: Amanojaku runs away

Some complicated plot because Lunarians

• ULiL: Outsider breaks barrier, invades
• LoLK: TL;DR Hell invades Moon invades Earth because grudge between moon person and earth person that flew to moon. Also American clown fairy

[PK]

• IN: Lengthened night by moon people to keep moon people out??? (Complicated plot? Lunarians)

The night was frozen by the youkai, not the lunarians (Either Yukari or Sakuya).

Yeah, the Lunarian trick was putting the Earth in a pot and painting a fake Moon on the lid.
So to speak.

Also pretty sure you can put everything from MoF to HM as one big "It's a Moriya Shrine epic screw up" arc, since they're all related to each other.

Really strange that you separate the "It's a Moriya Shrine conspiracy" arc in half, yet put UFO in the non-religious half.

religion war didn't start until buddhists built on top of a grave
