Pachauri is the librarian who manages the Red Devils Hall. After the change of red mist, the Red Devils' hometown, Mochisha frequented the library, nominally borrowing books but never returning them, which directly led Pachauri to take severe measures against Mochisha later. The countermeasure is to break into and steal books by force ... During the demon dream, Pachuli helped Mochisha find information about the changes in Chun Xue and the subsequent games. Marisa is a rare troublesome friend to Pachauri who lives in the library all day. As the only three magicians in the dreamland, Pachuli, Marisa and Alice have a good relationship. Generally speaking, they will set up a witch tea party, the main activity is to drink tea and chat. Marisa likes new things, and Pachuli likes some strange theories. Lily Xiang's colleagues think that Alice is crazy about Melissa, and Pachuli admires Melissa. As for Morisa, he is an ignorant fool and likes to be with the witch Boli.
