My name is Dorona, and I have the ability to communicate with parallel worlds. My peers often help me. I also have a master who loves eating marshmallows and can travel through parallel worlds like me. He said that we are the same kind and taught me how to use my abilities. I will continue his family in the future.
I spoke out confidently: What's the conflict between me being a vigilante and me inheriting the family?
(Don't worry, I just have a close relationship with Bai Huahua, the CP is not him)
(There will be a tutoring plot, with characters from Demon Slayer and Fumino visiting)
