Eleven characters are available in
Immaterial and Missing Power, including Suika Ibuki, who had her debut in this game. The characters Remilia, Yuyuko, Yukari, and Suika must be unlocked by defeating them in story mode, and Meiling is unlocked by downloading a
patch, and completing the story mode, though she does not appear in it. • ''''
(博麗 霊夢): The miko of the Hakurei Shrine and perennial protagonist of the Touhou Project''. She is troubled by the constant feasts in the shrine that she has to host, and goes to attack whoever she thinks is responsible. Like in the
bullet hell games, she has access to homing projectiles. • ''''
(霧雨 魔理沙): An ordinary human magician, and playable character in each main Touhou
game since Phantasmagoria of Dim. Dream''. She acts as the secretary in charge of the feasts, though she is unsure of their cause. • ''''
(十六夜 咲夜): The maid of the Scarlet Devil Mansion introduced in The Embodiment of Scarlet Devil''. Sensing a mysterious
qi in the feasts, she sets out to investigate. Her main ability consists of being able to throw large amounts of knives. • '''''' (アリス・マーガトロイド): A human magician, who lives in the Forest of Magic, alongside Marisa. Alice attempts to
exorcise the aura, believing it to be a ghost. She attacks using
puppets that she creates. • '''''' (パチュリー・ノーレッジ): A
witch from the Scarlet Devil Mansion who does not usually go out of her library. This time, however, she took responsibility in investigating the mist that has been blanketing Gensokyo. Patchouli is
asthmatic, and has poor mobility, but compensates with magical barrages that cover a large area. • '''''' (魂魄 妖夢): A half-human half-
ghost, and Yuyuko's gardener and servant. Youmu starts fights with various innocents, assuming them to be the culprits. Her attacks are centred around the usage of her two swords. • ''''
(レミリア・スカーレット): A vampire, and mistress of the Scarlet Devil Mansion, who is thought to be one of the prime suspects in creating the strange mist, because she did it once before in The Embodiment of Scarlet Devil. Because of her childlike physique, she is able to move quickly, and release danmaku'' that cover a wide area. • ''''
(西行寺 幽々子): The ghost princess of the netherworld. She is also believed to be a suspect, as she orchestrated the incident in Perfect Cherry Blossom''. Reflecting her lazy personality, Yuyuko lacks mobility, but her Spell Cards have an unmatched range. • '''''' (八雲 紫): A wandering
yōkai, who controls the Hakurei Border. • ''''
(伊吹 萃香): Introduced in Immaterial and Missing Power
, she is an oni who loves drinks, feasts, and competition, like the rest of her race. Despite her small size, she is strong in strength, speed, and mystic powers; she is also several hundred years old. 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 continuous feasts, intending to draw the joyous oni'' from hiding. • '''''' (紅 美鈴): A Chinese-like yōkai and martial artist that was included in a later patch of the game. She has no story mode. == Development ==
