Family Tree:
Gojo clan
Branches--> Kiyooka, Maeda, Hisamatsu, and Higashibōjō. There used to be a fifth family.
Each one has married into the Gojo clan at one point or another. Every clan mentioned here is a descendant of Sugawara no Michizane or claims to be.
Satoru is close to her Kiyooka family; the relation and much of the family dynamics will be explained in munificence.
Satoru has a big ass family and has to manage them all.
Gojo Satoru--> Unlike canon, she is very intentional. This might be due to gender changes, but she's still canon Gojo: arrogant, goofy, complex, lonely, and carrying the weight of the world. She wanted an equal, so she looked for an acolyte and found one.
Fushiguro Megumi-->similar to canon but has thrived in an environment carefully orchestrated by Satoru. Megumi is complex. She exists in a patriarchal macrocosm, but she has many role models in her life, but her favorite is a woman with the duality that grants her a seat at the table. Megumi contradicts the omega and female stereotypes. She is a powerful shaman with the education of an heir. Where does she fit? At Satoru's side? Is that all she will amount to?
Fushiguro Tsimiki-->raised to be an ally for Megumi, conditioned to be a place of strength for Megumi, given every opportunity to make sure she doesn't feel inferior to Megumi, brought up around Satoru's family to show that normal people exist in shaman families.
Megumi is one year younger than Tsumiki, she has a late birthday so she's two years below her in school. A second year junior to her high school freshman.
