Reimu Hakurei is the shrine maiden protagonist of Touhou Project, the long running Japanese bullet hell game series created by ZUN. The character has inspired a huge volume of fan games, fan anime, music and voiced edits online, which is where short clips like this angry take circulate. Fans cut single irritated lines for soundboards and meme edits because the mood reads instantly, even out of context. That portability has kept Reimu reaction sounds popular across anime and gaming communities long after the original games.
