Touhou Project

The Touhou Project (or simply Touhou) is a series of Japanese shoot-'em-up bullet hell games designed by ZUN.

History
Following the release of the series' sixth game The Embodiment of Scarlet Devil, which is the first installment for Windows PC, the series garnered a massive fanbase.

Touhou's popularity in Japan led to many fan works and doujins, with some of them being videos shared through the website Nico Nico.

SiIvaGunner
SiIvaGunner has featured Touhou in over four hundred rips (including rips of the Touhou discography).

The creator of Touhou and its music, ZUN, appears as a character in the King for a Day Tournament and its sequel.

In 2016, Lenox (who was not yet a team member at the time) began a trend of asking "Touhou album when?" in the comments of almost every rip related to Touhou, since SiIvaGunner had yet to publish an album dedicated to Touhou. The album SiIvaGunner Presents: Somewhat Responsive to Requests ~ Touhou Album Now! was eventually released in December 2020, after having been in development since 2017.
