Sukuna Ryomen Yuji Itadori and Megumi Fushiguro are a Duoplex Spirigenic Traumagenic Programmed System!
A Duoplex or Duplex describes two or more systems who are linked in a way that they may share an inner world. It may be fully combined, or linked in another way (gates, portals, doorways, etc.)
Spirigenic refers to systems that were created for or through spiritual means, with an emphasis on religious spirituality
Traumagenic refers to a system whose creation / origin is the result of one or more traumatic events. Often, these systems have lingering trauma, and may fall under a diagnosis like DID or OSDD-1
Programming is the process of using trauma-induced dissociation to implant commands and structure in a system by an external group
Sukuna Ryomen is a Isoldawn ASPDbased Malicitor Sub-System!
Isolgenic or socinagenic is an origin in which a system, headmate, subsystem, or other structure formed due to isolation and/or social neglect
An ASPDbased system is heavily influenced by having ASPD (Antisocial Personality Disorder), with it possibly affecting the innerworld, headmate roles, or the headmates themselves, but isn't a system origin
A Malicitor is a system member who seeks to harm others for their own personal gain, rather than than to the benefit of their system
A Subsystem is a system within a system; oftentimes, when an individual member has a system of their own, such as a contained subsystem
Yuji Itadori is a Outernaut and Vernalian!
An Outernaut is an alternative to the term host. It's a headmate who is primarily in charge of fronting, external life, and daily matters. A system may have one, multiple, fluid, or no outernauts
Vernalian is a polyrole umbrella term that refers to a headmate who has multiple roles that relate to promoting positive emotions, and helping process and dispel negative emotions. They may have other roles that fall outside of these concepts that can be listed separately
Megumi Fushiguro is a Grief Holder Trauma Holder and Janusian!
A Grief Holder is a headmate who holds grief relating to death and loss. They can front to take grief from another member who has dissociated to the point of being unable to feel grief, or process it healthily. They may also come co-con with another member to allow them to grieve. This is considered a role
A Trauma Holder is simply any headmate that holds significant trauma, often to keep others within the system safe from that knowledge. They are more common in traumagenic systems, but can be found in systems of any specific origin since trauma may also be experienced at any time after a system has already formed. These headmates can also be referred to as "holding trauma"
A Janusian is a headmate who can function as both a protector and/or a persecutor depending on the situation
