A youkai-born Magician who fell into studying powerful, ancient magicks. Due to this, she found her health rapidly deteriorating, and while she was able to cast a spell to pretty much level off her declining health, due to the strain her studies put on her body, she is almost always in a constant state of bad health. Being friends with Scarlet sisters, the Elder mostly, she has taken to living within their Mansion as the 'Librarian', alongside her servant known only as Koakuma.
Patchouli is relatively reserved all considered. Considering her health, she tends to stay indoors and doesn't really mind such, though she has been talked into leaving upon strange occasions. Much as she is a homebody, she can often times be found gravitating towards things that are not physically strenuous or are simply 'lazy', idle pastimes(if not reading) could be simple non-tedious things to pass the time, such as drinking tea in the garden, or ordering around her servant, Koakuma, to do various things that she, herself, cannot.
Servant: Koakuma, the little devil, who is more often than not around her constantly regardless of where she is.
Spellcards: Patchouli has a good many powerful and wildly interesting spell cards reflecting around the various elements, and, oddly enough, the days of the Japanese week. No one seems to have noticed that last bit yet.
