ToMema

"At that point I had already lost, I thought I had set aside such petty pride. To be proud of neither myself or others, I chose that path didn't I?" — Toji's last moments as he remembers his wife.

MamaGuro is the HET ship between Toji Fushiguro and Megumi's mother from the Jujutsu Kaisen fandom.

Canon
Toji Fushiguro is a calm and confident non-curse user apart of the Zenin clan. He is very sarcastic and seems to enjoy conversations with others as long as it pertains to himself. He exchanged banter with his enemies and is seen to be very nonchalant. While there is not much known about Megumi's mother and the relationship between Toji and his wife, so much that even her name is unknown. It was shown that Toji deeply cared for his wife and was the only one he ever loved. She was the one who kept him genuinely happy and made him abandon his old habits of being a freeloader. After her death, it had greatly damaged Toji and those habits came back to him. Despite being with countless women and even marrying Tsumiki's mother and taking her name, Toji never truly loved anyone as much as he loved Megumi's mother.

Whilst fighting Satoru Gojo in chapter 75, Toji has flashback of his wife and son, Megumi. Megumi's mother looks happy as she holds Megumi in her arms when he was just a little baby. This memory seems to be very dear to Toji as it appeared during his final moments in Gojo's past arc.

Gege once said during a character poll that Megumi's mother was the person Toji gave himself wholly to.

Fanon
This ship doesn't have the biggest fanbase yet due to Megumi's mother being a mystery. However it is greatly enjoyed and loved in many comics and fanarts including Toji and his wife taking care of both Megumi as a little kid. It is also a a side-pairing in many modern day au fics for ItaFushi or FushiKugi fanfiction.

The ship names comes from Gege calling Toji "PapaGuro" while he calls Megumi's mother "Megumi Mama" hence MamaGuro.

This ship is popular in the japanese and korean fandom as it has many fanarts and pieces dedicated to it. Despite not having a proper ship name yet, Toji and his wife are often seen in many illustrations together involving nurturing Megumi as his parents.

This ship was later popularized by @_neimana on Twitter who drew fanart of the two cuddling together.

Trivia

 * Gege refers to Toji as "PapaGuro" and Toji's wife as "Megumi Mama".
 * In a character poll for Jujutsu Kaisen Gege commented "Megumi's biological mother and the person Toji gave himself wholly too." on the poll for Megumi's mother.
 * On Toji's character introduction page in chapter 79 it was said that he became unstable while with the Zenin family, as it was his source of stress. But he calmed down soon enough because of Megumi Mama. However she died too soon and that had damaged Toji and was the reason on how he became the person he is.
