Future episodes ideas or guesses.
(From the opening of the series:)- An episode about the backstory of Byakuren and Murasa (mainly Murasa) during her years as a human before her death. (bonus if the Sealing Club explores Okinoshima in their side of their story).
- An episode about the backstory of saigyouji yuyuko and the saigyou ayakashi (can bordered with a retelling of Ghostly Field Club too)
- A "retelling" of Changeability of Strange Dream, which can also border with the backstory of Fujiwara no Mokou.
(Miscellaneous:)
- An episode about the backstory of the Four Devas of the Mountains, albeit slighty reworked since Suika Kasen is a thing.
- An episode that explores more of Youkai Mountain and the youkai that lurk on it, mainly the Tengu Hiarechy.
- An episode that explores the past of Renko's ancestor: Usami Sumireko, from her past towards her times in gensokyo from the normal series, and maybe even her adulthood too.
- An episode that explores both Maribel and Renko's past before forming the Secret Sealing Club.
- An episode that centers on Rumia.
- An episode that centers on the Beast Martriach Families and the lives in the Animal Realm
- An episode that centers on Marisa Kirisame and her backstory. Can also pulls things from the Pc-98 stuff too. (Bonus points if Reimu gets envidious of Marisa now that she had her own episode too.)
- An episode that centers on Reimu's backstory, or more importantly, on the Hakurei Shrine's backstory and all the Mikos that served it.
- An "retelling" of Trojan Green Asteroid, that could be a "midquel" from episodes "Moon" and "Wish". Can or cannot have also a backstory of Nue Houjou too.
