metaphorical boundaries, which also distinguish her spell cards. Often, though, she just summons her shikigami and various others to create her danmaku for her. She is tall. Immaterial and Missing Power Species: Oni Ability: Manipulation of density and sparseness Residence: Gensokyo, often seen at Yokai Mountain and the Hakurei Shrine, exact location unknown Main antagonist of Immaterial and Missing Power, a playable character in Scarlet Weather Rhapsody, and a support character to Reimu in Subterranean Animism, her only appearance in a mainline Touhou game. Suika is an oni, and once part of the Four Devas of the Mountains, alongside Yuugi Hoshiguma and Kasen Ibaraki (the fourth one has not been revealed), but has since then retreated underground with the rest of the oni. As an oni, she loves drinks, feasts, and competition. Despite her small size, she is physically strong, and has, speed and mystic powers to match. Using her ability to control density, she can gather people to form a banquet, or she can scatter herself to become mist. In Immaterial and Missing Power, she made the residents of Gensokyo have feasts for several consecutive days, intending to draw the joyous oni from hiding. Suika (萃香) is the Japanese word for watermelon, and so this became an unofficial nickname for her. Her name is likely a reference to Mount Ibuki, where the oni Shuten-dōji was born. Imperishable Night Species: Yōkai firefly Ability: Manipulation of insects Residence: Bushes, grass Stage 1 boss. Insects collect around her, and so she often can be seen in the middle of a swarm of them. With her powers, she can manipulate the flickerings of fireflies with timed synchronicity, or summon swarms of poisonous insects to kill an enemy. Like insects, she is afraid of pesticides and the cold. She is seen wearing a cape and pant-like bloomers, which led fans to believe she was a male. She is often seen alongside Yuuka and other insect/bug characters. Species: Night sparrow Ability: Making humans insane by singing Residence: Youkai Trail Stage 2 boss and playable character in Phantasmagoria of Flower View. Mystia is a night sparrow that dwells on a road near a human village. She conceals herself by blinding travelers who walk along the road at night, then lures them astray, after which point they disappear without a trace. She is carefree, loves to sing, and considers her nightly activities nothing more than a game.
