アニメ第124話で初登場。妖怪ダリスはとりついた人間のやる気をなくしてしまい、横になってダラダラさせてしまう。「だるい」と「りす」から名前が付いたそうです。
Darisu is a member of the Shady Clan and makes its first appearance in episode 124 of the anime. In the form of a yellow squirrel with the card suits on its tail, Darisu is always lounging around. Anyone possessed by this yokai loses the will to do anything. The name [ダリス] comes from the joining of [だるい] ‘darui‘ which means ‘lethargic’ and [リス] ‘risu’ which is a squirrel.
