The "Half-Human Half-Phantom". Stage 5 boss of Touhou's Perfect Cherry Blossom and later a recurring playable character.
Gardener of Hakugyokurou, the netherworld pagoda, and bodyguard of its "princess", Saigyouji Yuyuko. She wields a katana, Roukanken, and a wakizashi, Hakurouken. Youmu specializes in rapid swordplay taught by her predecessor Youki, whose surname she took as a sign of succession. She is always followed by her phantom half, which floats beside her. She is nicknamed "Myon" in many fanworks, based on a nonsensical word she muttered back in PCB. Ironically, although she is half-phantom, she is terrified of ghosts.
