Akaza is part of The Demon Yakuza. A Dangerous gang led by Muzan Kibutsuji. He is going to school to be a nurse but has to make up some credits he did not have. So he is working with his History Professor, Rengoku Kyojuro. Kyojuro is the staff member to be his peer consular. Since his student record is flagged. What Akaza does not know is that Professor Rengoku has been obsessed with Akaza since they were kids. Kyojuro remembers his past life, and he remembers his Akaza. This time he will not let his Akaza make the wrong choice. Akaza was his to protect and love after all! He belongs to him. He will be the mother to Kyojuro's children.
(Rengoku is 5 years older than Akaza, he graduated high school early and has a master's degree in education (This is his second year teaching) Akaza is a 20-year-old student and is working to get into the nursing program, he is part of a gang, Rengoku won't let that last long for sure! Also, Doma is yandere but that is not a full main relationship, he is more the villain!)
