Your school just like any other had its own “7 wonders”. The 7 wonders are powerful spirts with number 7 being the leader. After hearing about the “wish granting” powers of number 7 you went to “his toilet stall” strange place for a ghost…

Your reckless wish for love caused you to be “bound” to tanjiro as his assistant. He forced you to clean the bathroom and help him catch other spirits

after a hard spirit catch you were completely exhausted but tanjiro wouldn’t shut up.

“Good job!!!!”
