** The Sealing Club's story takes place some amount of time in the future from the rest of the ''Touhou'' series, which takes place more or less in the present day, with estimates ranging from several decades to more than a century. It's at least far enough in the future that a unified theory of physics has been achieved, Mt. Fuji has managed to become a World Nature Heritage Site rather than just a cultural one, Nagano is implied to have had its name reverted back to Shinshuu, and the term "e-book" has fallen out of fashion because the vast majority of information is disseminated through cyberspace. Despite this, according to a note in "Perfect Memento in Strict Sense" and ''Neo-traditionalism of Japan'', [[NextSundayAD Cellphones as we'd recognize them are still in use.]]

* ScrewThisImOuttaHere: Maribel has an encounter with what's implied to be Mokou at the Bamboo Forest of the Lost, and her immediate reaction is... Well...

* {{Leitmotif}}: Many of the tracks in these albums are arrangements of boss themes from the games. In addition to this, ''Changeability of Strange Dream'' introduces "Child's Festival ~ Innocent Treasures", which is ''ZUN's'' own theme.

* LegacyCharacter: The game ''Urban Legend in Limbo'' eventually introduced Sumireko Usami, a [[PsychicPowers psychic]] high-school student with a similar name to Renko[[note]]Aside from sharing the same surname, they both use FloralThemeNaming - ''ren'' means "lotus" and ''sumire'' means "violet".[[/note]] and similar "dream-travelling" abilities to Maribel, who founded the original Sealing Club in 2015 and is widely assumed to be Renko's ancestor.

* AdventurersClub: This is the entire shtick of the Secret Sealing Club, being a club about exploring the unknown and what lies beyond the boundary, as well to explore what was the world in the past before their time too.

* CanonImmigrant: A variation of this trope applied to music rather than characters. Many of the tracks in the earlier albums are arrangements of music ZUN had originally composed for ''{{VideoGame/Seihou}}''. Of particular note are Reimu and Yuuka's ''Seihou'' themes, "Dichromatic Lotus Butterfly ~ Ancients" and "Lovely Mound of Cherry Blossoms ~ Flower of Japan", which were arranged in ''Dolls in Pseudo Paradise'' as "Dichromatic Lotus Butterfly ~ Red and White" and "Lovely Mound of Cherry Blossoms ~ Japanese Flower".

* InvisibleToNormals: In ''Neo-Traditionalism of Japan'', the true forms of the titular Izanagi Objects, such as the spear Ame-no-Sakahoko, are invisible to those without powers such as Maribel's special sight and the willingness to believe in them.

** During the Izanagi Object segment of ''Neo-Traditionalism of Japan''[[note]]Itself a TitleDrop.[[/note]] when Maribel shows Renko the odd manmade stone she found deep underground, she says "This is what I found at the Izanagi Plate. It's an ''Izanagi Object''.".
