Trivia / Koishi Komeiji's Heart-Throbbing Adventure

• Ascended Extra: This fan video series helped raising Koishi Komeiji's popularity up to eleven. The fact that Koishi being the first Touhou character other than Reimu, Marisa, or Sakuya who managed to win character poll in 2015 is very well known within the fandom. ^note Several years later, Youmu Konpaku won two character polls in 2020 and 2021
• Distanced from Current Events: Word of God at the beginning of Part 19 [6/9] said that due to several Islamic terror attacks (especially those in France), various scenes were reworked to remove civilians and/or undergo other changes, because the scenes were unintentionally way too similar to said Real Life atrocities.
• Genre Popularizer: KKHTA is not the first Touhou Dark Fic published, but it surely helped encouraging many fans to write their own "dark interpretations" of Gensokyo. After KKHTA's first video was published in 2009, Touhou DarkFics started appearing one by one. Imperfect Metamorphosis by Takerfoxx and Osana Reimu by Joyful are two of the most well-known Touhou DarkFics other than KKHTA.
• Sequel Gap: After part 8/9 of the Grand Finale was released in December 2016, it would take nearly six years for there to be any indication that the final part was on its way. Eventually, in March of 2024, Sentaku-bune would release a short trailer for part 9 on his YouTube channel.
