Comprehensive Comic: the Beginning Is a Marriage Certificate, the Fiancée Cang Na

Bai Yu traveled to the world of Demon High School and became the Astaros family, one of the Seventy-two Pillars of the Underworld, a family with the blood of the Time Demon God, and the sign-in system was enabled! When you sign in for the first time, you will receive a Gorgon Stone! At the beginning, his parents dropped a marriage certificate and asked him to take his partner, Sona, home! Bai Yu had no choice but to go to the human world to complete his parents' mission. I thought it was just a simple matter of flirting with the arrogant fiancée, taking Cang Na's daily life, and occasionally beating up Cao Cao and other villains. But it turns out... The development seems a little wrong. The vice president of Kuao School is called Shinomiya Kaguya! The Loli mascot is not only the Tacheng kitten, but also a two-dimensional amnesia girl who calls herself Athena! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
