Tanjiro Who Turned into a Ghost Is Killing Ghosts

The introduction is weak. To put it simply, it is a comprehensive world view of ghost, hibiki and demon slayer. Tanjiro acts as a ghost/ghost to destroy ghosts (made by Mukai). I'm thinking about whether to bring Hikari here to be a ghost (Wuxian: Your mother?) "I will use my life to continue the past and the future." "Senior Yuanyi, please lend me your strength!" "The pure voice of the ringing ghost will cleanse the filth." Intention: The way of heaven is good for reincarnation, no one will be spared by heaven.
