A witch who has settled down in the Scarlet Devil Mansion. Unlike the mistress of the house, she is not weak against sunlight; however, she does not go out much. She spends her days in a library where the sunlight cannot reach. This is so that the books won't be damaged, but the unhealthy atmosphere is bad for her health. She doesn't have a very proactive personality, but rather always walks her own path. However, she is always interested where knowledge is concerned and will proactively go and try to acquire it. She completely depends on her books, but still makes a lot of mistakes. Although she is quite skillful, her complete lack of physical fighting ability can't be helped. She pretty much never attempts to directly punch or kick her opponent. She makes up for this with her knowledge of a great variety of powerful magic. She's more at ease using magic than trying to attack physically. Dividing the magic she uses according to the days of the week is a secret hobby of hers, but no one has realized this.

Issa is a creature that looks like a stuffed panda. He refers to himself as "the empathic one" of the trio, puts the most effort into trying to be nice to Ami, and makes many unsuccessful efforts to make peace between Iyo and Kenta. His date of birth is the 23rd of November.
Ami, the protagonist of the Anime, is a five-year-old preschool student who has just moved into a new home and neighborhood with her family. She is intelligent and imaginative, but grounded and a bit easily flustered. The revelation that a gate to Ani-Yoko is in her room, and the increasingly bizarre actions of her three visitors, frequently drive her to the brink of total distraction, yet she seems to have gotten used to their presence, with Ami sharing some of her regular life with them. Her date of birth is 15th December. (Source: Wikipedia)
Sakuya is the only human living in the Scarlet Devil Mansion, yet she is also the head maid. The official fanbook suggests she had been a vampire hunter before she began working in the mansion, but she was defeated by Remilia Scarlet who pitied her and gave Sakuya her current name. Though she looks about sixteen like the other girls, Sakuya has the ability to slow, stop and possibly reverse time. She seems to have been serving Remilia for a long time and may be far older then she looks. Socially, she interacts mainly with the others in the Scarlet Devil Mansion. Her talents are cooking, knife throwing and time manipulation. The latter two abilities characterize her appearances in-game, and led to frequent parodies in reference to Dio Brando of JoJo's Bizarre Adventure, who also controls time and throws knives. This reference goes so far as Sakuya using some of his poses in a game. She is often associated with dogs by other characters because she is serving as a demon's "faithful guard dog" even though she is a full blood human. Due to the inconsistent artwork depicting her bust between games, d�jinshi often make fun of her by indicating that she pads her breasts. (Source: Wikipedia)
Emily is Break's little doll who usually sits on him. She sounds like "click click click", which with addition to her freaky smile makes her really scary for Oz.
A tengu who has been in Gensokyo for over 1000 years, when oni were still around. Her origin is a crow. She has the ability to manipulate wind. Her character is honest but not rigid. She is polite to strong people, and deals more firmly with weak people. However, she is always polite when conducting an interview. Although her powers are among the top class in Gensokyo, she never uses them just to show off. This isn't only a characteristic of hers, but of tengu in general. She usually lives on a mountain where the wind always moves at the same speed and the same direction. She loves gossip and is always gathering information exchanged with her fellow tengu. During any exchange, information is warped, and almost all of their stories end up exaggerated. She is the biggest connoisseur of rumors about the girls of Gensokyo among the tengu. Through observing for herself and collecting information from colleagues, barely a moment passes when she isn't obtaining material. However, much of her material is mingled with rumor. She writes up her non-periodical newspaper, Bunbunmaru News, and distributes it among the tengu. It's a newspaper chock-full of rumors. As the current disaster started up, the tengu were overjoyed. There was much new material to be obtained, based on which they can write up their newspapers. (Source: TouhouWiki)
