Scarlet Weather Rhapsody retained all characters from
Immaterial and Missing Power (except
Hong Meirin) while adding three pre-existing characters of the
Touhou Project into the game and introducing two new characters— bringing the total roster to 15 characters. • '''''' (博麗霊夢) - The
miko of the Hakurei Shrine, which was newly reduced to rubble. She sets out to find the one responsible for this and make her compensate for the shrine. • '''''' (霧雨魔理沙) - A magician living in the Forest of Magic. Troubled by the rain around her, Marisa tries to go to a place where the rain won't reach her. • '''''' (十六夜咲夜) - The head maid of the Scarlet Devil Mansion, noticing the energy flowing out of her body, she decides to find the cause. • '''''' (魂魄妖夢) - The gardener of Hakugyokurou. Noticing that ghosts were decreasing in number, she goes to investigate without telling her mistress Yuyuko. • '''''' (アリス・マーガトロイド) - A puppeteer magician who also lives in the Forest of Magic. Convinced that the strange occurrences are signs of an impending earthquake, she delves further in the matter. • '''''' (パチュリー・ノーレッジ) - The resident bookworm of the Scarlet Devil Mansion, she feels the change in the temperaments and puts the investigation upon herself since no one else seemed to realize what was happening. • '''''' (レミリア・スカーレット) - The vampire lady of the Scarlet Devil Mansion. Remilia has to stay indoors because rain, one of vampires' weaknesses, kept falling outside the mansion. Being bored, she had her servant maid Sakuya bring in suspects of the incident one by one. • '''''' (西行寺幽々子) - The mistress of Hakugyokurou. Although she was one of the earliest to realize the change in temperaments, she did not seek to put an end to the incident but used it to further her own ends - to enjoy a cool summer. • '''''' (八雲紫) - A
youkai who looks over borders, including the one at the Hakurei Shrine. Infuriated by Tenshi's plan to make the shrine celestial property, she seeks Tenshi out and destroys the newly rebuilt Hakurei Shrine. • '''''' (伊吹萃香) - A party-loving
oni who felt the temperaments were being gathered. Thinking the whole venture fun, she went up to Heaven to help turn Tenshi's prank into something more serious and to stay for the food and drink. • '''''' (射命丸文) - A newspaper journalist for the
tengu society of the mountain. While not searching for potential scoops, she guards the mountain from trespassers. • '''''' (鈴仙・優曇華院・イナバ) - A
moon rabbit who now resides in Eientei. By the orders of her master Eirin Yagokoro, she goes around warning people for earthquakes and investigates the aftermath. • '''''' (小野塚小町) - The
shinigami in charge of bringing souls to the other side. Now just wandering around and slacking off. • '''''' (永江衣玖) - An
oarfish (known as "messenger of the
Dragon Palace" literally in Japanese) whose task is to take notice of earthquake signs and warn the people of the inevitable disaster. Nominally under the command of the celestials. • '''''' (比那名居天子) - A
celestial who ascended to Heaven through no virtue of her own. The tempering of the temperaments and instigating earthquakes were all her doing, due to her being bored and wanting people to "defeat" her. ==Development==
