Chainsaw Man, the Fire Demon of the Contract Holy Lord

(People who have never seen Chainsaw can also enter the pit, and it is a barrier-free reading)
Standing in front of you now is one of the eight demons, the one who controls the power of fire, the absolute owner of the twelve talismans, the only remaining true dragon in the world, and the contractor of the famous demon wizard from ancient times to the present - the Holy Lord!
Su Tang!
-------------------------------------
Of course, Su Tang now has another identity.
A private psychiatrist working in Tokyo.
"But! Why are there so many mental illnesses in Tokyo!"
-------------------------------------
(Note: Because the original male protagonist of Chainsaw Man plays an irreplaceable role in promoting the plot, this book will transform the original male protagonist into a girl to avoid problems such as giving away a girl. If you don’t mind, don’t read it)
