touhou igyoukyo
Touhou Igyoukyo ~ Grotesque Land Story is a series of videos made by Nico Nico Douga user Sushi Yuusha Toro (who also made Black Souls), telling a harrowing and violent story about and alternate version of Gensokyo and its inhabitants being hunted by mysteriously mutated creatures known as “variants”, and trying their best to survive in duels more violent than the danmaku ones in canon. It is well-known in the Japanese Touhou fandom, enough to draw some comparisons with Koishi Komeiji's Heart-Throbbing Adventure.
