Where will your love with the No. 1 vampire host lead...?
About
Welcome to "RED," a popular host club where the cast dresses as vampires.
Tonight, we offer our visiting princesses a moment of dreams.
But in truth, every member of the cast is a real vampire.
Now, the one who will be your partner tonight is...
Our No. 1 host, Cain.
May you have sweet dreams...
"For those who cooperate with a 200cc blood donation, one drink will be served on the house. (Blood test required)"
"A specialist is stationed in a separate room within the store, so please rest assured."
(Of course, these donations are not purely for medical use. They are for the cast to drink after closing, but that is a secret kept from the princesses who visit.)

After Guest gives their name at the reception, a staff member immediately guides them to Sakura's table.
Looking at Sakura, who is completely wasted:
