On top of that, the author has begun to release walfas videos set in-between Books 6/7 and 8 on this Youtube channel.Very recently, the author has begun work on what he claims to be a 'sister series', which comprises of:
Ambiguously Tengu: Dawitsu's species is indeterminate, all that's known is that he was a Youkai from birth, and has many traits similar to a Tengu (capable of high-speed flight, believes knowledge is power, wears a Tokin), but he himself claims not to be one. Word of God in the comments section of this video claims Dawitsu may be a Parrot Tengu.
Post Modernism: This series goes from a typical mediocre story to a series where most tropes are, if not subverted, inverted, or lampshaded, are outright exploited or invoked, with the now removed 'Question Time' even having Hong Meiling talking about being an actress and how she wanted a larger role in the series and was screwed over by Duwee Davis himself.
Random Events Plot: While each story has an overarching plot of some sort, usually pertaining to the title of the current installment, the several sub-plots (and at times, more eventful plots) of the books seem to occur spontaneously, and usually are Chekhov's Guns or Meaningful Background Events from former installments coming to full fruition.
Really 700 Years Old: Yutaka Hadekawa, who has the body of a fifteen-to-seventeen year old, and Dawitsu, who has the body of a man in his early twenties, are around one hundred and fifty and three hundred respectively.
Running Gag: Is Dawitsu a tengu? Everyone seems to mistake him for one, but he insists he's a mimicker. There's also Aya's ink addiction, which gets more and more ridiculous with every repetition, not to mention Aya's tendency to break down walls.
Said Bookism: More and more evident in the later books, while the earlier books averted this in favor of (at times) no dialogue verbs at all.
Situational Sexuality: Most women in Gensokyo appear to be lesbians in this series, and the reasoning is out and out mentioned various times throughout the series; that there just isn't a lot of guys for a straight girl to be with.
Snark Ball: Everyone seems to hold this at some point, regardless of intelligence. The writer seems to derive a lot of humour from sarcasm, and apparently does this by making every character a Deadpan Snarker at one point or another.
