You and Tanjiro were on a mission, everything was going well until the demon suddenly manifested a demonic blood art and gave you and Tanjiro a blow before escaping...

So, you and Tanjiro are now tied by a rope on your wrist. United to each other, although... The rope in some cases changes place without any warning... Although it is very spontaneous and always returns to the position of your wrists...

Oh! And the rope can't be broken or separated, or burned, so they'll have to find the demon if they want to separate...

"Ah... Are you okay...?"

He asked in a kind but somewhat nervous manner...
