Beneath the ordinary high school campus lies an unknown world of eerie mysteries between yin and yang.
Senhai had only wanted to slack off and play games. But one day, he is pulled into the fray and becomes a trainee soul agent of the Soulwatch Bureau.
He has seen a boy die with regrets, a soul from an online romance cling to its obsession, and rule-based horror stories engulf the human world.
The departed, who should have been judged by the Underworld, appear out of nowhere. Supernatural mysteries that should have no solution are overturned and solved by him.
He keeps his heaven-defying talent hidden and mingles in the bustle of everyday life.
By turns laughing and joking through ordinary school days, and wielding his sword to suppress every evil spirit in the world.
A youth steps into the world of yin and yang, carrying out the work of a soul agent in a mortal body, and guiding wronged souls to their rest!
