The House of Spiders, led by one powerful member from each of the Five Fingers, was formed to raise an individual to be the perfect wielder of the Relic Arayashiki and turn them into a tool akin to a Concept Incinerator upon which they would be used as a "landfill" to dispose of anything the Fingers wanted forgotten.[5][6] To this end, someone with an aptitude to the Relic was required:[5] Shiomi Yoru, the Dihui Star of the Pinky, was chosen to bear a child and pass down the unique perception of time tied to her blood.[7] With her aptitude for Arayashiki and the skills she learned under the Nursefathers, Yoshihide was to eventually become a wielder of "Muga", achieving a state of non-self that would give her the ability to erase concepts and everything tied to them.[8] These concepts are not permanently deleted, but instead severed from reality in a way which makes them impossible to reach.[8] As the Muga, Yoshihide would have to forfeit her memories and reach a state of complete emptiness.[9] It is heavily implied that the Five Fingers intended for Yoshihide to erase the disgraced Nursefathers as her first act upon becoming the Muga.[10]

The members of the House were five high-ranking, yet largely disgraced members of the Five Fingers: a Sottocapo of the Thumb, an Oracle's Proxy of the Index, a Great Brother of the Middle, a Maestro of the Ring, and a Star of the Pinky. These five were the House's Nursefathers, responsible for Yoshihide's upbringing and training. Their base was the House of Spiders, a massive, secluded set of Corridors connected to the outside world in a number of random ways.[11] While most of the Nursefathers and Apprentices could leave as they liked,[12] and a number of other members of the Fingers knew where the House was and would visit it for tutor sessions,[13] the Pinky Nursefather was uniquely closed off from the world and forbidden from leaving its premises.[14]
