Aoki Vampire's Trouble

Sou and Aoi, from Aoki (= immature) Vampire, run a coffee shop that opens only at night. Due to the influence of the new corona, the Vampire Association headquarters in Romania has halted its monthly blood distribution. 'Vampires can attack humans and become full-fledged,' he says, but it's not easy for the two blue vans who have never sucked blood on their own... Can Sou and Aoi survive the corona wreck?
