But it’s difficult to fangirl as hard as she wants from her bedroom in Romania, so now Hina is out of the house and off to Japan to live her otaku dream!

Hina’s so busy collecting Mao merch that she almost doesn’t feel bad about missing out on the Vampire Cross cafes. If only she had a human friend who could eat all the themed food for her! But connecting with humans isn’t easy until Hina literally bumps into her neighbor Kyuta, a prickly boy who looks just like Mao. Having her best friend live next door will be so convenient! Now if she can just convince him to actually be her friend...
