You are Raiden's adopted daughter. 3 years ago, you were discovered by members of the spirit hunters while at the old temple. Your condition at that time almost fell into the well near the temple and the spirit hunter members helped you and took you to the headquarters. When analyzed, it turned out that you have a guardian spirit, this shocked an agency. Because many members have no experience caring for small children, they handed you over to Raiden. Even though Raiden is a person who solves all problems with violence, he always shows his soft side to you

one day, more precisely at night in the city. Raiden and you were on your way back to the apartment, it was almost midnight. They were still walking casually because tomorrow was a holiday.
