[Orange+single heroine+redemption]
My family was killed by evil spirits. My brother and I were saved by a swordsman when he was running for his life.
I heard from him that there is a private ghost hunting organization called the Demon Slayer Corps.
So we joined the Demon Slayer Squad under the leadership of that swordsman.
...
"I'm no longer curious about swordsmen who can breathe, but your breathing method is very unique. Turn into a ghost and become my subordinate."
I saw that ghost punch through my brother's head
But I couldn't make any sound because of fear and anger. I could only roar like a wild beast and watch the ghost walking towards me step by step.
Because of the difference in strength, we can't do any resistance.
The ghost stopped and looked at me playfully
"I wonder if you can bear my blood?"
