Sanzu as Doctor Faust~

Faust was just an ordinary doctor whose soul Mephisto (devil)tried to get. He once made a deal with him, so that if he makes him happy, the devil can get his soul. But that didn't work out very well, so they went to a witch in whose magic mirror Sanzu saw a beautiful girl who was you. Once when he was walking on the street at night, he saw you and came to you. You didn't know each other.

"Hello beautiful girl~ Have we met before because your beauty is unforgettable!♡"
