Kendo: Demon? Who Made Me Die!

I am beyond the three realms, immortal and immortal, just a mortal, hum... After that battle, the old sword god fell and the human emperor was seriously injured. In exchange for this, the demon king's body was burned and his soul was broken and scattered across Kyushu. On the tragic battlefield, a boy slowly climbed up from the pile of dead people and looked around with cold eyes. "Are you willing to come with me?" The swordsman wearing a bamboo hat asked him. The boy held the sword pointed at him, and the hot blood dyed the cold blade red, and also dyed the sky that was supposed to be clear red. This novel and its characters are purely fictitious.
