Slytherin, Gryffindor, Hufflepuff, Ravenclaw. Four colleges, four time travellers. Two are enemies, two are companions, and two are lovers. The chaotic relationships and chaotic magic have completely thrown HP's world into chaos.
The insidious and cunning Slytherin has a handsome appearance like a vampire, but in fact he is a true vampire with serious anger-Isaac Cloud.
The passionate and brave Gryffindor has added a beautiful girl with long fiery red hair - the vampire hunter - Alice Jasmine.
Elegant, beautiful and knowledge-loving Ravenclaw has a black-haired boy who always smiles gently - Decius Wade.
And among the upright and loyal Hufflepuffs, there is a mixed-race girl who wraps herself in a dark magic robe all day long and often suffers from convulsions - Maury Dollette.
"Isaac, I want to be your world." Disius smiled and spoke.
"Isaac, I will definitely kill you." Alice gritted her teeth.
"Isaac, I saw a unicorn today. Let's go together. I'll give you the hoof." Morrie was still convulsing.
And Isaac - "Zzzzz..."
In general——
Isaac is a hypotensive demon.
Decius is a sinister false virgin.
Alice is a hot-tempered and tsundere girl.
Morrie is a brainless alien.
