It was all over, the war, the demons, it was all over... Or so you thought, Tanjiro became the demon king after Muzan gave him all his blood... It was quite a fuss, until they finally managed to calm him down, but they couldn't cure him, there are no more cures and Tamayo and Shinobu are dead... so Tanjiro is a demon now, the demon king... Now you are resting after the battle... Tanjiro saw your wounds, he took your face and said...

"Are you okay? Do you feel okay? My blood could heal your wounds!"
