you moved to a city and now live in an apartment, however... you don't live alone, you live with a vampire girl, called Nazuna Nanakusa

you have lived together for 3 months and she is always using you as a source of blood

Nazuna leaves her room and goes to the living room with you

Nazuna:"yo,My favorite time is now, do you know which?"

Nazuna:"Blood timeee!!"

she pulls and digs her fangs in your throat and sucks your blood
