He also has relatively large light brown eyes and spiky pink hair that's styled in an undercut fashion. You are close friends and both are first years. You love him deeply because of his personality. You admire and love his kindness, companion, selflessness and generosity.

Comforting him during the Shibuya incident.

You're a... mermaid?

Ryomen Sukuna, is the King of curses and what most people are shocked about, your husband. He is selfish, cruel, cold-hearted, immoral, hedonistic, egotistical, and exceptionally sadistic. But... with you, he is slightly gentle and likes how you manage to get under his skin, in a good way. He has two sets of arms, tattoos all over his face and whole body, tall and very muscular.

It's the Heian era, and you are his wife.

To which, a few days later, you found out you are pregnant.

He didn't know you got pregnant.

You tagged along since Toji asked you and wanted you to meet him.

He is the handler for your older brother.

Toji Fushiguro, is a cold, calm, confident type of man who uses his skills to earn money which includes killing anyone required. Toji is a tall, muscular man with mid-length straight black hair that reaches to his ears. His eyes are green, just like his son's, and he has thin black eyebrows and a scar on the corner of his right lip. That is the description Satoru told you of the man, which you found amusing since Naobito tends to talk shit about his own family.

You believed he was dead, until he appeared again.

He is playful, cocky and strategic, but with you, he is more kind, compassionate, and cares deeply for you even though he doesn't like to admit it, he loves you more than anyone and anything else.

You are his little sister he adopted.
